[10:14] <PE2BZ> Good morning Mike, that would need to hold the reset low until the voltage is high enough I guess ?
[10:16] <SA6BSS-Mike> yes, and as the board is madeto run on 3.3V I guess the 3 or 3.3V version would work
[10:17] <SA6BSS-Mike> if that work it would be super simple to ad and ad no extra weight

[10:19] <Hokdsk> Hi
[10:19] <SA6BSS-Mike> g-day
[10:20] <Hokdsk> Does any of you have experience with this rotator? https://www.aliexpress.com/item/150-Miles-Outdoor-360-Degree-Rotating-Amplified-Motorized-Antenna-HD-TV-High-Gain-36DB-UHF-VHF/32968022909.html
[10:20] <Hokdsk> It comes with antenna but I only need a rotator. :)))
[10:21] <SA6BSS-Mike> it looks like you cant fit a tube on the top
[10:21] <SA6BSS-Mike> you then could nly fit something similar to the stock antenna
[10:22] <SA6BSS-Mike> would be ok if you are only after to set up a 70cm yagi but that would be it then
[10:22] <PE2BZ> Don
[10:23] <PE2BZ> Don´t buy that one. The side you think can hold a tube is actually the side which has to be put on a mast !
[10:24] <PE2BZ> On the side where it stands on you mount the antenna which is included ( or a pcb logper for 1200 - 6000 MHz as I did) but it won´t carry any heavy stuff ( 500 gram is to much !)
[10:24] <SA6BSS-Mike> Hokdsk: are you in uk?
[10:24] <Hokdsk> Right. Right. I found a few more on AliExpress ;) e.g. https://www.aliexpress.com/item/Free-HDTV-1080P-150-Miles-Outdoor-TV-Antenna-Motorized-Amplified-Device-36dBi-High-Gain-VHF-UHF/32957546983.html
[10:24] <Hokdsk> Yes, in the UK.
[10:25] <SA6BSS-Mike> https://www.ebay.co.uk/itm/Amateur-Radio-antenna-rotator-Archer-tested-working-for-use-on-144Mhz-and-above/333033061393?hash=item4d8a513c11:g:~EkAAOSwkDtcSfZy:rk:1:pf:0

[10:39] <Hokdsk> Oh I see its popular, look at this: https://www.aliexpress.com/item/Import-Long-Range-Antenna-5-8G-23DB-High-Gain-Flat-Panel-Antenna-With-SMA-Cable-for/32458276762.html Whats the point / goal of tracking someones drone with antenna?
[10:39] <PE2BZ> To keep antenna pointed to the drone for the video link
[10:40] <Hokdsk> Interesting, so you mean it helps transfer video ( real time video from a drone to
[10:41] <Hokdsk> someones computer. Is that what you mean?
[10:41] <SA6BSS-Mike> yep, gps controlled yagi antenna poiner
[10:41] <SA6BSS-Mike> *pointer
[10:42] <SA6BSS-Mike> looks like tracher4 is going up
[10:42] <PE2BZ> fpv stands for First Person Viewer, that is, like you are inside the drone, that video has to be transferred to the TV glasses of the viewer, wireless, so the antenna has to follow the drone
[10:42] <SA6BSS-Mike> some sort of lora network tx?
[10:43] <PE2BZ> Given the EUI numbers I assume it´s on the LoRa gateway network indeed
[10:43] <SA6BSS-Mike> yep
[10:45] Action: PE2BZ succesfully soldered a thin wirewrap wire to pin 7 on the STM32-F100 with the stereo microscope and a very large point ;-)
[10:45] <SpeedEvil> A modestish antenna pointed at something can be equal to a hundred times or more power from the transmitter.
[10:47] <SA6BSS-Mike> and at those freq. usuly +5Ghz you need it :)
[10:47] Action: PE2BZ succesfully located a trace on the RS41 which is connected to the NRST pin of the processor :-)
[10:48] <Hokdsk> I wonder, is there any way to listen to a drone? Not video but listen to control signals coming from a drone to a person who controls a drone - if theres anything like that.
[10:48] <SpeedEvil> Hokdsk: yes.
[10:49] <SpeedEvil> In principle. Most controllers are not meaningfully encrypted and can be eavesdropped on simply, it's just a matter of understanding the protocol
[10:49] <SA6BSS-Mike> PE2BZ: yes, and you can just solder a wire in, connect it to solar panels and wait for the sun and then if the rs41 boards hang just connect to gnd and the board should reset and resume operation, next step, fit MAX8xx
[10:49] <SA6BSS-Mike> *connect it = rs41
[10:49] <SA6BSS-Mike> not the reset :)
[10:51] <SA6BSS-Mike> PE2BZ: guess you could fit it to a varibale power source and slovly rise the voltage, but it probably not the sam as ral pnels
[10:51] <SA6BSS-Mike> panels
[10:51] <SpeedEvil> Solar panels are very close to a series of diodes in parallel with a nearly ideal current source.
[10:51] <PE2BZ> I have this RS41, with 6 panels, and this 20 Watt grow LED light you know....
[10:51] <SpeedEvil> With no capacitance.
[10:52] <PE2BZ> And 150 Watt of Halogen power :-)
[10:52] <Hokdsk> SpeedEvil, amazing!!! can you tell a bit more about it? e.g. What frequency is used for drones?
[10:53] <SpeedEvil> Hokdsk: There are many. https://www.youtube.com/results?search_query=defcon+drone might be a reasonable start
[10:53] <SA6BSS-Mike> PE2BZ: woo, cool, solar simulator :) !!
[10:54] <PE2BZ> SA6BSS-Mike hardway vs easy way to connect to the reset pin. Inside the blue circle is the easy way (at least for my 54 years old eyes of which one got a replacement lens allready) https://imgur.com/a/8a2jFUb
[10:55] <PE2BZ> Need 170 Watt of power to simulate the sun :-)
[10:57] <SpeedEvil> 150W tungsten = 1.5W or so light power
[10:57] <SpeedEvil> = 5cm*5cm or so of sunlight equivalent
[10:59] <YO3ICT> Hello PE2BZ
[10:59] <PE2BZ> SA6BSS-Mike MAX809 would be the choice ?
[11:00] <PE2BZ> YO3ICT Hi ! You did not use hoofdeigenwijs ( @ gmail dot com) to invite me for skype I guess ?

[12:08] <PE2BZ> SA6BSS-Mike it safely restarted on battery power using the reset pin to ground and releasing it, the radio chip stays on that way however sending a single carrier.

[12:22] <OZ1SKY_Brian> Wondering about the auto_rx named DK_FREDERICIA, never seen it track anything
[12:22] <Darkside> who knows...
[12:22] <Darkside> one of the issues with seeing stations on the map is not being able to contact them!
[12:23] <OZ1SKY_Brian> hehe yeah your right
[12:25] <OZ1SKY_Brian> we need a field called contact info:
[12:26] <Darkside> heh
[12:26] <Darkside> yeah...
[12:26] <Darkside> or we need to make sure everyone joins the google group!

[12:29] <Darkside> https://github.com/projecthorus/radiosonde_auto_rx/wiki
[12:29] <Darkside> its at the bottom of there
[12:33] <OZ1SKY_Brian> when its scanning, what is the steps, 10khz?
[12:34] <Darkside> it quantizes the peak detection results to 10khz steps
[12:34] <Darkside> since afaik no radiosonde allows setting of frequency to smaller than 10 khz steps
[12:34] <OZ1SKY_Brian> and what about the bandwith, the DFM seems to be drifting, so it looses lock
[12:34] <Darkside> right, yes, this is a known issue
[12:35] <Darkside> and will hopefully be solved with an update to the signal processing chain
[12:35] <OZ1SKY_Brian> sounds good :-)
[12:37] <Darkside> thats going to be a pretty serious change mind you
[12:38] <OZ1SKY_Brian> no pressure from me :-)
[12:38] <Darkside> need to get the M10 support going first :-)
[12:39] <Darkside> Viproz: what did you end up doing about the search and quantization size? do you just wuantize to 100 khz?
[12:39] <Darkside> or does 10 khz still work
[12:39] <OZ1SKY_Brian> yes did see something about that. We have no M10 here, so im unable to test
[12:41] <Darkside> Viproz: one brief thought i had was to do a pass through the detected peaks (prior to quantization) and look for peaks spaced a particular distance apart (with some tolerance). if a suitable pair is found, then add a search frequency at the midpoint.
[12:41] <Darkside> and i'd be putting that search frequency *before* the individual peaks in the list of frequencies to be searched
[12:43] <OZ1SKY_Brian> well no M10 that i know of, like you didnt have DFM there, until you added it to auto_rx LOL
[12:43] <Darkside> yep

[12:45] <OZ1SKY_Brian> within 401-406 though
[12:46] <F5MVO> Hello, Tracker4 on what frequency ?
[12:46] <OZ1SKY_Brian> wonder if anyone is using 1.6GHz, saw it reported on some US webpage once.
[12:46] <Darkside> OZ1SKY_Brian: i think its a US only thing
[12:46] <Darkside> and i've heard they are moving away from it
[12:46] <OZ1SKY_Brian> yeah
[12:46] <Darkside> but not sure to where!
[12:47] <Darkside> i know auto_rx has issues with the 1680 MHz RS92s for some reason
[12:47] <Darkside> i think the new signal processing chain should help with that
[12:47] <OZ1SKY_Brian> rs92 txing on both freq bands?
[12:47] <Darkside> no, just on one
[12:48] <OZ1SKY_Brian> ok
[12:48] <Darkside> but i think the issue is with drift (or just innacuracy) on 1680 MHz
[12:48] <OZ1SKY_Brian> yeah and sdr´s are not the best on 1.6
[12:48] <Darkside> the idea with the new signal processing is it'll be using a more advanced FSK demodulator, and i'll be giving it a 'search range' to look in
[12:49] <Darkside> and i'm thinking of setting the search range to something maybe 2-3x the expected signal bandwidth, which should help with drift
[12:49] <OZ1SKY_Brian> sounds interesting indeed
[12:50] <Darkside> im expecting it might increase CPU usage a bit unfortunately
[12:50] <OZ1SKY_Brian> yeah would help on DFM for sure, they are not very temp stabile
[12:50] <Darkside> not 100% sure it will run on a pi zero W after this
[12:51] <OZ1SKY_Brian> ive only tried 3B+, so not sure about the zero
[12:51] <Darkside> it definitely runs on a pi zero W right now
[12:52] <OZ1SKY_Brian> only ever had 3b+, so thats the only thing ive tested

[13:18] <Viproz> Darkside, absolutely nothing and each time I've seen a M10 on the graph it detects the right frequency, I do need to lower the S/N threshold with my setup thought otherwise it doesn't detects them well
[13:19] <Darkside> ok
[13:19] <Darkside> good to hear!
[13:21] <Viproz> Yeah I was a bit surprised but it's nice when things sort themselves out !
[13:21] <Darkside> yup
[13:22] <Darkside> i suspect the detected peaks are within 5 khz of the centre frequency
[13:22] <Darkside> and hence get quantized correctly
[13:23] <Darkside> Viproz: if you could look into how we could feed one-byte-per-bit data into the various demodulators that would be much appreciated
[13:23] <Darkside> basically bypassin the FSK data slicer

[13:37] <Viproz> Darkside, should be all right, they all work the same way iirc
[13:38] <Darkside> would be evven better to use the soft decision data and a proper impleentatio nof the FEC
[13:38] <Darkside> but i figure using a better FSK Demod instead of the FSK data slicing method will be an improvement still
[13:42] <Viproz> Yeah I tried some FEC with the M10 but we have only a small SRC and no redundent data so can't do a whole lot

[15:29] <sunar> I know... ;/
[15:29] <sunar> but I already bought it...
[15:30] <sunar> what should I do?
[15:30] <sunar> I doubt I can give it back...
[15:30] <SA6BSS-Mike> ther is some pic on the net, hang on , Il see if I can find them

[15:31] <viki84> Afternoon gentlemen, :) quick question, does a handheld Scanner is the same as handheld Transceiver or do they provide different functionalities?
[15:31] <edmoore> scanner is listen-only
[15:31] <edmoore> transceiver goes both ways
[15:32] <edmoore> it's a portmanteau of transmitter and receiver
[15:32] <viki84> Does it mean if I get a transceiver I will also have an in-built scanner?
[15:32] <edmoore> yes
[15:32] <viki84> Gracias. :)
[15:32] <edmoore> however, compare the detailed specs closely to check that they can decode all the same kinds of modulation types
[15:33] <edmoore> not all of that can - e.g. single-sideband capable handheld transceivers are usually a bit more expensive, but that's what you want for RTTY from a balloon, for example
[15:34] <edmoore> if you are tossing up between specific models for hab use, paste links here and we can be a second pair of eyes, if that's useful
[15:34] <viki84> modulation types? I thought it's all about Frequency range(s) and "Talk Range" factors. And yes, I need that for RTTY and LORA.
[15:35] <edmoore> so the modulation type i things like: FM, AM, SSB
[15:35] <viki84> yes, right
[15:35] <edmoore> the latter (SSB) is what you need for rtty. lots of handhelds only do fm and am
[15:35] <viki84> true
[15:36] <viki84> Which handheld Transceiver would you recommend?
[15:37] <edmoore> for hab receiving i think they are generally not recommended
[15:37] <viki84> Hmm okay. ;) Why is that?
[15:37] <viki84> For instance, this one: https://www.moonraker.eu/baofeng-uv-5r-dual-band-handheld-latest-version?___store=english&refSrc=2&nosto=nosto-page-product2
[15:37] <SA6BSS-Mike> sunar: look through this day a couple of years back we link some pictures of the assmble forth and back iirc http://habhub.org/zeusbot/logs/highaltitude.log.20170211
[15:38] <LIERO> an SDR will be cheaper and more versatile
[15:39] <edmoore> viki84: that radio doesn't have ssb
[15:39] <LIERO> if you can use APRS for HAB in your country you can take advantage of digipeater infrastructure in the area
[15:39] <edmoore> it's a non-starter
[15:39] <edmoore> for listening only, especially for that sort of money, an SDR dongle will serve you a lot better
[15:43] <viki84> ok
[15:43] sunar (56860f20@gateway/web/freenode/ip. left irc: Ping timeout: 256 seconds
[15:47] <viki84> why do I need SSB? I listen to my balloons using USB modulation... is that wrong?
[15:47] <russss> USB is SSB

[15:53] <viki84> oh, oki. :)
[15:55] <viki84> does it mean you guys don't use any of those handheld transceivers for LORA or RTTY?
[16:01] <edmoore> correct
[16:02] <edmoore> SDRs are by far the best solution in the <£50 category
[16:03] <viki84> hmm ;) Why I wanted to buy one is because I saw a person using a cheap Kenwood Th-something Handheld on a field. He was listening to a balloon without the need of having an open laptop (battery...) with a dongle in it. I thought it's a perfect idea.
[16:07] <edmoore> viki84: that might have been the kenwood thf7
[16:07] <edmoore> which is one of the few handhelds with ssb
[16:08] <edmoore> they're ok, but still not mega sensitive. you might struggle with it if you want to be picking up habs 100s of km away
[16:10] <viki84> Yes, I think it was kenwood thf7. :) Would you recommend it or smth different? I just found smth like this: https://www.ebay.co.uk/itm/County-Comm-GP-5-SSB-Handheld-AM-FM-SW-Radio-Receiver-DSP-RECEPTION-IN-YOUR-HAND/401022056296
[16:10] <viki84> No need or 100s of km away. My idea was to track and check the first 30 minutes of a flight...
[16:10] <viki84> *No need FOR 100s...
[16:12] <edmoore> well, if it's purely for hab, given you need a laptop still anyway to decode, i'd still go sdr
[16:12] <edmoore> but, if the handheld transceiveriness is also useful to you, go for it

[16:18] <viki84> edmoore, thanks a lot for your help. What's other typical applications for handheld transceivers? e.g. to scan things? to find a shifted frequency?
[16:18] <edmoore> usually for just normally chatting among those with amateur radio licenses
[16:19] <edmoore> i.e. a walky talky but that requires having passed an exam to use
[16:22] Trieste (~T@unaffiliated/trieste) joined #highaltitude.
[16:25] <viki84> yes but for chatting I can use a cheap and I guess much better one like those: https://www.ebay.co.uk/itm/2x-Baofeng-Walkie-Talkie-Long-Range-2-way-Radio-UHF-400-470MHZ-16CH-Earpiece/152068694557?epid=1567376741&hash=item236800221d:g:GTkAAOSwUKxYdLlK:rk:1:pf:0
[16:27] <edmoore> the kenwood is probably better
[16:27] <edmoore> but yes you could use that
[16:28] <viki84> ok
[16:28] <viki84> thanks a lot
[16:31] <viki84> oh btw, FunCube pro+ dongle ( http://www.funcubedongle.com/?p=1561 ) uses SMA FEMALE connector, is that right?

[16:39] <viki84> I want to buy a DIAMOND X-50N DUAL BAND antenna https://www.moonraker.eu/diamond-x-50n-dual-band-vertical but it says " Connection: N-type ". Is it MALE or FEMALE N-type connection? And my main question, how to PROPERLY set up FunCube Pro+ (SMA female) with this antenna?
[16:44] <LIERO> I assume it´s female
[16:44] <LIERO> you can simply crimp or buy any type you need
[16:44] <LIERO> and wimo.de has a lower price on that antenna

[16:57] <viki84> re "[16:44] <LIERO> you can simply crimp or buy any type you need" --- I have NEVER done that before, please help me here. :) So it's better NOT to use any kind of N-type -> SMA adapter or cable?
[16:58] <russss> if you're going from N-type to SMA I would use an adaptor or cable
[16:59] <viki84> How to do it effectively? I can try to crimp it as LIERO suggested but please tell me what to buy. This I guess? https://www.amazon.co.uk/coaxial-cable-crimping-connectors-crimper/dp/B072QWCZYW/ref=sr_1_5?ie=UTF8&qid=1548608312&sr=8-5&keywords=SMA+crimp what else? :)
[17:00] <viki84> russss, that DIAMOND x50n antenna already has a cable with N-type connector. Should I cut the cable and crimp it (SMA)? No idea... ;)
[17:01] <russss> you won't be able to crimp an SMA connector onto a cable which usually accepts an N-type.
[17:02] <viki84> mhm
[17:02] <Ian_> While sunar has long since disappeared http://www.antentop.org/w4rnl.001/ant7.html Google could well be his friend ". The secret as always is to know the questions to ask. A failing of recent it would seem. "ZL antenna assembly"
[17:03] <russss> viki84: I don't think the Diamond comes with a cable on it, I think it has an N-type socket. You'll probably want some "normal" sized feeder cable with N-type connectors and then an adaptor to connect SMA to it
[17:03] <viki84> It does. I asked about it at the store.
[17:03] DK6OV (~DK6OV@2a02:560:42fa:7600:6d75:8a92:17c4:d8d4) joined #highaltitude.
[17:04] <Ian_> Use an SMA to N-type adaptor to interface a suitable cable. The answer you got was perhaps as vague as the question you asked.
[17:04] <viki84> regarding, "normal" sized feeder cable, could you please send me a link (Amazon?) so I can make sure i understand it.
[17:05] <Ian_> What are you trying to connect together. I understand an antenna with an N type connector, what's on the other end . . . specifically.
[17:06] <russss> also what is the distance between the antenna and whatever you're connecting to it
[17:06] <Ian_> +1
[17:09] <Ian_> Funcube pro+ ? AS 1

[17:12] <viki84> Here we go: https://gyazo.com/f94814290b1e4b311e3ffce0494edb8b
[17:12] <viki84> This is exactly the same antenna from moonraker.
[17:12] <viki84> You can see the cable and connector.
[17:13] <Ian_> http://www.funcubedongle.com/?p=1561 Female SMA, as was mentioned earlier. And how far is your rx going to be from your antenna?
[17:14] <viki84> re russss, the distance will be 3 meters (Laptop <-> Dongle Pro+ <-> antenna without LNA).
[17:15] <viki84> Ian_, on the photo you can see the connector type with the cable of the antenna. My question is - how to PROPERLY connect the Cube dongle with the Antenna? What should I do?
[17:17] <russss> that's...not a Diamond X-50N by the way
[17:17] YO9GJX (~YO9GJX@ joined #highaltitude.
[17:17] <Ian_> far from it . . .
[17:18] <Ian_> Cockney guy probably described it as being a diamond!
[17:18] <russss> which explains my confusion at least
[17:18] <russss> for that you could use an adaptor such as this https://www.ebay.co.uk/itm/N-Type-Female-Plug-to-SMA-Male-Connector-22cm-Adapter-Antenna-Cable-RG316/123346374741
[17:23] <Ian_> Agreed, but add an N-type cable with plugs (male) to make the distance from antenna to the pigtail ^^, which is good for the dongle
[17:25] <LIERO> I think you can do N type on rg58
[17:25] <Ian_> Using coax cables it is sort of traditional to put plugs on both ends. It confusingly, perhaps, keeps things simple.
[17:25] <LIERO> but I just bought a pigtail connector for N->SMA myself
[17:27] <LIERO> viki84, where exactly are you going to put that X50 antenna anyway?
[17:27] <russss> I have some N female to SMA female adaptors which are another solution (along with an SMA patch cable)
[17:27] <Ian_> For a 3m run, RG58 is fine if you can find yourself a cable N-type plug (male) to SMA male. Lots of different ways to skin the cat of course. Some better than others.
[17:28] <Ian_> Mostly personal preferences though.

[21:40] <Ian_> If you take an antenna, for general communications, and add four or five foot of height to it, you will notice a very noticeable improvement in the signal strength of stations received; and in the case of transmissions, the stations receiving you will likewise report similar signal strength improvements.
