[07:15] <nosebleedkt_> Good morning all !
[07:16] <UpuWork> moring
[07:16] <junderwood> Still looking good for a launch tomorrow
[07:16] <UpuWork> hey number10 your full exam did you do the tests at hamtests.co.uk ?
[07:16] <UpuWork> which launch is that junderwood ?
[07:17] <number10> yes
[07:17] <junderwood> Vortex & HelioSS from Chalgrove.
[07:17] <junderwood> I put a message on the list a few days ago
[07:17] <UpuWork> missed it so many atm :)
[07:17] <UpuWork> when is howest going up ?
[07:17] <junderwood> Maybe someone could add it to the tracker?
[07:17] <UpuWork> did you find the questions on there relevant to the exam number10 ?
[07:18] <UpuWork> hang on those launchest are next weekend junderwood ?
[07:18] <UpuWork> oh wait no thats SOTON
[07:18] <UpuWork> too many launches
[07:18] <UpuWork> gotcha
[07:18] <UpuWork> tommorrow
[07:18] <junderwood> :)
[07:19] <junderwood> One payload up, two down
[07:19] <number10> some of them were not not as useful as in the intermediate UpuWork
[07:19] <UpuWork> ok
[07:19] <number10> HOWEST is saturday initially 1130UTC - they were going to delay to 12:30 UTC
[07:19] <junderwood> If we launch at 9:00 am, it may even land at the launch site
[07:20] <number10> as we were initially going saturday
[07:24] <nosebleedkt_> Hello everybody. Today I was at civil air traffic control offices. We had a positive discussion although they have never met a situation like making a NOTAM for a HAB. So they asked me if anyone has a sample NOTAM from past missions.. They want to see how and what your foreign officers wrote on the NOTAM.
[07:27] <UpuWork> right
[07:27] <UpuWork> spacenear.us should be correct now
[07:29] <junderwood> Upu, thanks

[11:31] <cuddykid> :O wicked!
[11:32] <cuddykid> Randomskk: what alt are you expecting?
[11:32] <Randomskk> can't remember - it was to be 15km for three stages but had to reduce it to 2 sadly
[11:32] <Randomskk> (because we didn't have time to fit fins and other gubbins to the third stage)
[11:32] <cuddykid> wow
[11:32] <Randomskk> haven't seen sim results for two stages
[11:32] <Randomskk> fairly high though i imagine :P
[11:32] <cuddykid> :D
[11:32] <Randomskk> it's an N motor and an M motor, and the third stage was to be another M.
[11:33] <cuddykid> is it actively guided? So do the fins or whatever move around do keep it firing up vertically?
[11:33] <Laurenceb> is the idea to launch the same thing off a balloon?
[11:34] <Randomskk> cuddykid: no - static fins
[11:34] <Randomskk> the whole thing was built in a few weeks
[11:34] <Randomskk> no time for anything overly complicated
[11:34] <Randomskk> (the internals are complicated enough for parachute and staging electronics)
[11:34] <Randomskk> Laurenceb: no, too heavy
[11:34] <cuddykid> ahh ok, yeah - I'm amazed how quick this went together
[11:34] <Randomskk> though we plan to launch it three-stages some time
[11:34] <Randomskk> Laurenceb: 40kg fully fuelled 3 stages
[11:34] <Randomskk> and very very tall
[11:34] <Laurenceb> insane
[11:35] <Randomskk> wrong motor design for 100km from a balloon
[11:35] <cuddykid> get some mahhooooosive balloons
[11:35] <Randomskk> you want different burn parameters
[11:35] <Randomskk> for high altitude ignite
[11:35] <Laurenceb> yeah
[11:35] <cuddykid> ah
[11:35] <Randomskk> might have to get some motors custom made
[11:35] <Randomskk> anyway back to revision
[11:35] <WillDuckworth> how so?
[11:35] <Laurenceb> you want long burn time?
[11:35] <WillDuckworth> nozzle expansion i suppose
[11:35] <Randomskk> don't need to go slowly at the start because thin atmosphere iirc
[11:36] <Randomskk> so can just have insane speed from the start
[11:36] <Laurenceb> yeah, pretty much
[11:36] <Randomskk> also we want it very fast out the launch rail so it's broken mach before it punctures the balloon
[11:36] <Laurenceb> nice
[11:36] <cuddykid> awesome
[11:36] <Randomskk> practically before it leaves the launch rail last I saw
[11:36] <Randomskk> which is insane
[11:36] <Laurenceb> or you could spin it...
[11:36] <Randomskk> still want to go fast
[11:36] <Laurenceb> true
[11:36] <Randomskk> spinning just helps reduce requried fin size
[11:37] <Randomskk> at the cost of a lot of faff
[11:37] <Laurenceb> not id its _fast_
[11:37] <Laurenceb> as in 50hz or so
[11:37] <Randomskk> fast is less faff or?
[11:37] <Laurenceb> well
[11:37] <Randomskk> at 50hz you don't need much fins
[11:37] <Randomskk> wonder if we could use small active fins
[11:37] <Laurenceb> yeah
[11:37] <Randomskk> anyway i really must go back to revising
[11:37] <Laurenceb> at 50hz you point and shoot
[11:37] <Randomskk> also then we would literally be building a guided missile
[11:38] <Randomskk> with ballistic range
[11:38] <Laurenceb> yeah
[11:38] <Laurenceb> itd be suborbital
[11:38] <Randomskk> well yea
[11:38] <Laurenceb> 100km even with off the shelf
[11:38] <Randomskk> downrange distances get silly once you can break 100km altitude
[11:38] <Laurenceb> motor
[11:38] <Randomskk> get on some watchlists for sure
[11:38] <Laurenceb> lol
[11:38] <Randomskk> maybe launch during olympics
[11:38] <cuddykid> Randomskk has Iran in his sights
[11:39] <Randomskk> see if the high velocity missiles stand a chance
[11:39] <Laurenceb> this is how i did my N-prize design
[11:39] <Randomskk> can't believe they are manually laser sighted
[11:39] <Randomskk> human operator doesn't have a chance to keep a laser trained on an incoming supersonic with any kind of useful angular velocity
[11:39] <Laurenceb> ~50hz spun off the shelf reload with CF tube body
[11:39] <Laurenceb> lol good point
[11:39] <Randomskk> the hvms are mostly for jet fighters not missiles though I guess
[11:39] <cuddykid> one of the ones they're using accelerates to mach 3.5 (I think) in no time
[11:39] <Laurenceb> then you can do 200km orbit with two stages
[11:39] <Randomskk> anyway not going to have it ready in time nor do we particularly want to all get shot so
[11:40] <Randomskk> cuddykid: yea.
[11:40] <Randomskk> the hvms
[11:40] <Randomskk> no prox fuse on the munitions though
[11:40] <Randomskk> gotta impact
[11:40] <Randomskk> and it's laser guided by a human operator
[11:40] <cuddykid> ah
[11:40] <cuddykid> lol
[11:40] <Randomskk> Laurenceb: orbit?
[11:40] <Randomskk> that's insane
[11:40] <cuddykid> crazy
[11:40] <Laurenceb> say goodbye to houses opposite
[11:40] <Randomskk> Laurenceb: total cost?
[11:40] <Randomskk> Laurenceb: yea....
[11:40] <Laurenceb> Randomskk: cost is....
[11:40] <Randomskk> hypervelocity white hot shrapnel
[11:40] <Laurenceb> kind of hard to calculate
[11:41] <Randomskk> sad times for anyone on the other side
[11:41] <Laurenceb> how much is your time worth
[11:41] <Randomskk> mm indeed
[11:41] <Randomskk> rough material expenses?
[11:41] <Laurenceb> £1K
[11:41] <Laurenceb> N-prize
[11:41] <Randomskk> it doesn't sound like two stages of cots motor plus spin off a balloon would cost much
[11:41] <Randomskk> we've spent like £11k on marlet-1
[11:41] <Laurenceb> yeah, but to be fair thats hard
[11:41] <Randomskk> I guess it is the 'it's hard'
[11:41] <Laurenceb> three stage would be easier
[11:41] <Laurenceb> in many ways
[11:41] <Randomskk> still I'm surprised no one's done it already if it's doable
[11:41] <Laurenceb> as for two stage youd need a custom stage 2 with high mass fraction
[11:41] <Laurenceb> above 80%
[11:42] <Randomskk> hm
[11:42] <Laurenceb> which is hard to diy in CF
[11:42] <Randomskk> maybe we should be thinking about orbit after we have the rockoon to 100km working :P
[11:42] <cuddykid> then moon and beyond
[11:42] <Laurenceb> imo balloons is the wayt o do it
[11:42] <Randomskk> for useful sized payloads?
[11:42] <Laurenceb> but it _has_ to be spun fast
[11:42] <Laurenceb> imho
[11:42] <Laurenceb> 20grams
[11:42] <Randomskk> then again even a radio transmitter in orbit would be a lot of fun
[11:42] <Randomskk> cuddykid: moon base is on our long term plans list ;P
[11:43] <Randomskk> right, revision.
[11:43] <cuddykid> haha :P
[11:43] <Laurenceb> cya
[11:43] <cuddykid> same :(
[11:43] <Laurenceb> you know whats funny
[11:43] <Laurenceb> i have to mark exam papers right now
[11:44] <cuddykid> if only I did EE
[11:44] <Laurenceb> then your marking would be piss poor
[11:44] <cuddykid> haa

[18:50] <fsphil-laptop> a radar reflector may be required where you are
[18:50] <fsphil-laptop> in the uk they're not necessary
[18:51] Boggle (~Jon@cpc1-cmbg10-0-0-cust144.5-4.cable.virginmedia.com) left irc: Ping timeout: 276 seconds
[18:51] <smrtz> how so?
[18:52] <fsphil-laptop> radar can probably pick up the payload anyway even without it
[18:53] <smrtz> if it's not necessary in the UK, is that just because your planes/other things with radar have "good" radar?
[18:54] <fsphil-laptop> that I couldn't say
[18:54] <smrtz> ahh, ok, well, I'll assume that I dont need one then.
[18:54] <fsphil-laptop> check with your local aviation authority. best not to assume
[18:55] <fsphil-laptop> just in case something goes badly :)
[18:55] <smrtz> fair point. will do
[18:55] <smrtz> as for the antenna, I'm building a bazooka, via an online guide, but is there a base length that you would recomend?
[18:56] <fsphil-laptop> I used one of those on my first flights, worked well
[18:56] <fsphil-laptop> your length will depend entirely on the frequency you use
[18:56] <fsphil-laptop> each half of the bazooka will be a quarter of the wave length
[18:56] <fsphil-laptop> roughly
[18:57] <smrtz> oh, so for436.650Mhz...
[18:57] <fsphil-laptop> http://www.csgnetwork.com/freqwavelengthcalc.html
[18:58] <fsphil-laptop> 171mm
[18:58] <smrtz> heh, just found that
[18:58] Laurenceb_ (~Laurence@host86-177-58-185.range86-177.btcentralplus.com) joined #highaltitude.
[18:58] <fsphil-laptop> it won't be exactly that, but it'll be very close
[18:59] <smrtz> yea, so go half a foot over, and then tune it down a few milimeters at a time
[19:00] <fsphil-laptop> I made it about 5cm longer but yea
[19:00] <fsphil-laptop> it tunes fairly well
[19:00] <smrtz> oh, ok, haha
[19:00] <smrtz> what do you use now?
[19:00] <fsphil-laptop> quarter wave vertical
[19:00] <fsphil-laptop> it's a bit shorter
[19:01] <fsphil-laptop> well, half :)
[19:01] <smrtz> how is that diffrent? mine is just upsidedown, right?
[19:01] <fsphil-laptop> http://www.flickr.com/photos/fsphil/5642986472/in/set-72157626013096240
[19:02] <smrtz> oh...
[19:03] <smrtz> advantages?
[19:07] <fsphil-laptop> easy(ish) to build
[19:07] <fsphil-laptop> and robust. there's no joins to break or snap
[19:07] <fsphil-laptop> it's just coax
[19:08] <smrtz> ahh, would you recomend it over a standard one?
[19:08] <smrtz> wait, vertical, as in vertical bazooka, right?
[19:09] <Hiena> fsphil-laptop: nice. Now build another 15 and connect it to an array.
[19:09] <fsphil-laptop> that's just a 1/4 wave vertical
[19:09] <fsphil-laptop> a vertical bazooka is a dipole made of coax
[19:09] <fsphil-laptop> it's twice as long
[19:10] <fsphil-laptop> although can be made quicker
[19:10] number10 (568422a2@gateway/web/freenode/ip.86.132.34.162) joined #highaltitude.
[19:10] <smrtz> ok, because the bazooka is 1/2 wavelengh
[19:10] <fsphil-laptop> yea
[19:10] <smrtz> I should probobly go with that then, and do a more advanced antenna later
[19:10] <Hiena> Yup. And yet possible to build an array from it.
[19:11] <smrtz> would you recomend a second one, on the radio on earth, thats hooked in to my computer?
[19:11] <fsphil-laptop> use the best antenna you can get on the ground
[19:11] <fsphil-laptop> what radio are you using in the payload btw?
[19:12] <smrtz> ok, I'll probobly still be makeing it... and an NTX2 434.650
[19:12] <smrtz> I read it wrong its not 436, my bad.
[19:15] <smrtz> 173 mm. I wonder how much of that is the top, and how much is the braid portion...
[19:17] <Randomskk> oh my god php
[19:17] <Randomskk> http://eindbazen.net/2012/05/php-cgi-advisory-cve-2012-1823/
[19:17] <fsphil-laptop> smrtz, both
[19:17] <fsphil-laptop> they should be equal
[19:17] <Randomskk> using PHP-CGI on apache? woo! all your pages are open to remote code execution
[19:18] <Randomskk> also all your source code -- all of it, including that settings.php file with your passwords -- trivially remotely viewable
[19:18] <Randomskk> by trivially I mean put "?-s" on the URL
[19:18] <Randomskk> and all this because they wanted to get a unit test passing /so disabled a cgi security check/
[19:18] <Randomskk> *in 2004*
[19:18] <smrtz> uhh, oh. http://www.iw5edi.com/ham-radio/?the-vertical-bazooka-antenna,18 is confusing..

[19:20] <Randomskk> well obviously that is one way to mitigate the issue
[19:20] <Randomskk> better, just don't use PHP
[19:20] <smrtz> you could just not use PHP.
[19:20] <jonsowman> i wish i could ban topics
[19:21] <smrtz> lol Randomskk.
[19:21] <Randomskk> jonsowman: irssi plugin probably
[19:21] <Randomskk> regex -> ban
[19:21] <nigelvh> Better is to use a language that works despite your predjudices, and work with the evolving issues and fix them as they come.
[19:21] <jonsowman> lol, would lead to confusing discussions
[19:21] <Randomskk> if by confusing you mean amusing

[19:22] <Randomskk> but also I won't say php for the rest of the evening to avoid antagonising :P
[19:22] <Laurenceb_> exam go well?
[19:22] <nigelvh> To summarize: I don't agree. People have choices. Don't use it if you don't like it.
[19:22] <smrtz> meh, this just when over my head. I know vary little about programming.
[19:22] <Broliv> Hello
[19:23] <smrtz> Hey, Broliv
[19:23] <Randomskk> Laurenceb_: better than expected
[19:23] <Laurenceb_> great stuff
[19:23] <Randomskk> yea
[19:23] <nigelvh> That's good news.
[19:23] <Randomskk> now have three days to revise hard for the next four ;D

[19:23] <Laurenceb_> and spend less time on irc :P
[19:23] <Randomskk> I don't see why I'd do that :P

[19:25] <Randomskk> I just pop in and out of irc occasionally
[19:25] <Laurenceb_> what i was saying about spin stabilised rockets
[19:26] <Laurenceb_> there are a _few_ issues
[19:26] <Randomskk> "few" or _few_?
[19:26] <nigelvh> or 'few'
[19:26] <Laurenceb_> e.g. its never going to be properly balanced, so it must not shake itself to bits
[19:26] <nigelvh> for *few*
[19:26] <Broliv> I'm pretty new to all this but I'm interested in launching my own hab. I need some help and advice for a noob.

[19:32] <smrtz> any recomendations on a cheap radio reciver?
[19:32] <Randomskk> haha that sounds good
[19:32] Action: Randomskk fires up the predictor
[19:32] <edmoore> 10km alt start for 4pm today above Ben Armine lodge sea level descent 7ms
[19:32] <edmoore> It fired beautifully
[19:32] <daveake> smrtz AOR AR8000, Yupiteru MVT7100, Yaesu FT790R
[19:33] <edmoore> Got first stage back, main didn't deploy
[19:33] <edmoore> But it's not too bad
[19:33] <edmoore> Can't find upper stage tho in the short time we had
[19:33] <Broliv> Thanks for the info randomskk and smrtz!
[19:33] <edmoore> Hence predictions request
[19:33] <Randomskk> edmoore: can't run prediction for the past. can do it for now...
[19:34] <edmoore> Caches anywhere?
[19:34] <Randomskk> 20:00 UTC anyway
[19:34] <edmoore> Do what you cam
[19:34] <Randomskk> they kind of partially exist but no real way to use them
[19:34] <edmoore> Will be better than my 2 bars of signal here
[19:34] <edmoore> That's all we have
[19:34] <smrtz> daveake: daveake the only one I'll be able to afford is the yaesu FT790R, have you worked with it?
[19:35] <Randomskk> 20:00 UTC hsa landing 58.1365 -4.017
[19:35] <daveake> Yes, excellent receiver. Except it died and is being repaired :p
[19:35] <daveake> All 3 are in the £75-£115 range
[19:35] <daveake> Yupi should be the cheapest
[19:36] <smrtz> nice, actually, I copyed it over wrong. I can't find it on google.
[19:36] <daveake> But prices on ebay are a bit variable depending on how many keen bidders there are
[19:36] <smrtz> ahh, you're going off ebay
[19:36] <Elmar_PD3EM> I found the problem I had with the libs and interrupts.......

[19:37] <Randomskk> ok
[19:37] <Randomskk> running for 1500UTC = 1600BST
[19:37] <Elmar_PD3EM> it had nothing to do with the libs and interrupts... ;-)
[19:37] <Randomskk> eroomde: 58.167 -4.085
[19:37] <jonsowman> * edmoore ^
[19:37] <smrtz> yeah, thats out of my budget.
[19:37] <Randomskk> jonsowman: the predict code php, I can just comment out "waah no running in the past" and it still works so long as current gfs data set covers that time
[19:38] <jonsowman> i know
[19:38] <Randomskk> perhaps make the 'in the past' check the same as the range of the current data set so you can run a bit into the past
[19:38] <jonsowman> but it often doesn;t
[19:38] <Randomskk> mm
[19:38] <jonsowman> so until the predictor can actually check for available data, i disallowed it
[19:38] <Randomskk> fair enough
[19:38] <jonsowman> right now, luckily, there is data
[19:38] <edmoore> Randomskk: Thanks
[19:38] <Randomskk> edmoore: so did the top stage not fire?
[19:38] <edmoore> Yea itdid
[19:38] <edmoore> Was amazing
[19:38] <Randomskk> oh cool
[19:39] <Randomskk> sweet
[19:39] <edmoore> Longest 9secs of my life
[19:39] <Randomskk> can't wait for the photos/videos :D
[19:39] <Randomskk> haha I bet
[19:39] <Randomskk> any idea of final altitude?
[19:39] <edmoore> So we expected 9 secs between stage burnout and second stage light
[19:39] <edmoore> But it was about 19s
[19:40] <edmoore> And I as expecting massive recriminations about my electronics and software
[19:40] <Randomskk> hehe
[19:41] <edmoore> Then we remembered that it was 4km up so it was an extra 10s of sound travel
[19:41] <edmoore> The bid is cool
[19:41] <Randomskk> aaah nice
[19:41] <daveake> ah
[19:41] <SpeedEvil> :)
[19:41] <SpeedEvil> Did you realise it was 4km up in that 10s?
[19:42] <edmoore> Total deathly silence then massive willing when we hear the bang and whoosh of the 2nd stage

[19:49] <smrtz> could i just get a 70cm ssb antenna, and connect that to a normal radio?
[19:50] <daveake> ssb is a radio function; nothing to do with the antenna
[19:50] <smrtz> ahh
[19:51] <daveake> If this is for just 1 or 2 launches, remember that receivers hold their value very well, and you can sell on for more or less what you paid
[19:51] <smrtz> well, it's for a school physics project
[19:52] <smrtz> and I don't think that my high school would be able to pay for it if it's so expencive
[19:53] <jonsowman> you're receiving data from a 10mW transmitter hundreds of km away, you need sensitivity, and that's not very cheap
[19:53] <jonsowman> there's an inherent cost to the receiver that you can't really get around
[19:53] <daveake> Well, a balloon is £50+, helium is about the same, parachute half that, tracker will cost £60 to make, so £70 or so for a receiver is in the same area as other major parts
[19:54] <daveake> And the receiver is the main thing you can sell after
[19:54] <jonsowman> and you're guaranteed not to lose it :D
[19:54] <daveake> true :D
[19:54] <jonsowman> well, unless you're doing it /really/ wrong
[19:55] <r2x0t> ^ put receiver on the balloon, transmitter on the ground.... OOPS
[19:55] <jonsowman> hehe
[19:55] <daveake> "Well the receiver is up in the payload, what do I do with this transmitter?" :p
[19:55] <daveake> oh, too slow :D
[19:56] <jonsowman> smrtz: i realise it's hard to convince the school to give you money for stuff like this, i had to get around that for 2 years and 2 HAB projects
[19:56] <jonsowman> they eventually realise it's worth it
[19:56] <jonsowman> when they get loads of publicity and parents at open evenings going "wow this is cool"
[19:57] <smrtz> yeah, I know. sad right? they aggreed to pay for it, the number I gave them was under $200.
[19:57] <smrtz> well, US dollers.
[19:58] <smrtz> (123.5788 British pounds sterling)
[19:58] <jonsowman> yeah, you won't do it for that realistically
[19:59] <smrtz> yeah, I've got everything going up planned out, just wasn't expecting another $100 for a reciver
[19:59] <jonsowman> do a bit more fundraising :)
[19:59] <jonsowman> you could try and borrow one if there is a radio club locally
[19:59] <jonsowman> but you'll need it for testing and launch
[20:00] <smrtz> hmm, maybe, and testing is basicly going to be the set up, in my hands with a reciver pointed at me, right
[20:00] <jonsowman> yes, but lots of it!
[20:00] <jonsowman> if you can find someone who'll loan you one for a couple of months then you're sorted
[20:01] <jonsowman> but otherwise i'd look into buying one
[20:01] <jonsowman> the FT790 is a good radio
[20:02] <smrtz> hmm, I can't find a working one on google. how much do they normally go for?
[20:02] <jonsowman> £100 ish

[20:27] <smrtz> would this work? http://www.radioshack.com/product/index.jsp?productId=2501194&retainProdsInSession=1&ab=CMSPhoneAndRadioCommThumb
[20:28] <Randomskk> unlikely - probably FM only
[20:28] <daveake> Unless is has SSB, no, and AFAIK none of the Bearcats do
[20:28] <smrtz> Randomskk: check the tech specks
[20:29] <smrtz> daveake: right, forgot about that
[20:29] <Randomskk> smrtz: what about them?
[20:29] <daveake> Very very few scanners have it
[20:29] <Randomskk> the tech specs don't specify receive mode
[20:29] <Randomskk> so it's almost certainly FM
[20:29] <Randomskk> (also it says includes noaa weather which is fm, so...)
[20:30] <daveake> I checked some Bearcats before, and none of the ones I looked at had SSB
[20:30] <smrtz> Randomskk: rigt, I had forgoten about the ssb requirement
[20:30] <Randomskk> in theory you can actually transmit FM
[20:31] <Randomskk> but you lose a good deal of range
[20:31] <SpeedEvil> And are _much_ more vulnerable to interference
[20:31] <smrtz> over an NTX2? and how much range?
[20:31] <Randomskk> I really wouldn't do it :P
[20:31] <smrtz> aww, you got my hopes up
[20:31] <Randomskk> can't really put a number on how much range
[20:32] <Randomskk> honestly ssb and a capable receiver is the way to go :P
[20:32] <SpeedEvil> with rtty - you are vulnerable - badly - in a 600hz or so band, quite badly in a 4khz band
[20:32] <SpeedEvil> With FM, that spreads to over 50KHz
[20:32] <daveake> Another receive option is the Funcube Dongle, but it's the same price area as the other options
[20:33] <smrtz> Randomskk: you're saying rtty wont work over ssb? or rttb over fm is vulnerable?
[20:33] <Randomskk> rtty over fm is bad
[20:33] <Randomskk> rtty over ssb is what we all do
[20:33] <daveake> We do use rtty over ssb
[20:33] <smrtz> ok, good, thats what I'm doing aswell
[20:36] <smrtz> but I could get anything with ssb, and build a 70cm antenna, right
[20:36] <Randomskk> no
[20:36] <Randomskk> the receiver must be 70cm ssb
[20:36] <Randomskk> the antenna /also/ has to be 70cm resonant
[20:36] <smrtz> frick, ok thanks
