[01:07] <W1MXJ> Hi! Back home now and I recovered one sonde! I also got pings of 3 more on the ground, but they were located in inopportune locations far from the road, in recently-planted fields, so recovery was aborted. Still, great to have a recovery to my name!
[01:07] <W1MXJ> Now the real question is where this set of sondes was launched from.

[18:53] <PE2BZ> Hi Thomas, congrats on your first recovery :-)
[18:54] <PE2BZ> Do you have history from the IRC messages from today ?
[18:55] <PE2BZ> I am quite convinced your screenshot does not show an DFM sonde
[18:56] <PE2BZ> The rtl devices have an 28.8 MHz crystal or tcxo, which multiplied by 14 ends on 403.2 MHz + or - some ppm correction.
[19:01] <PE2BZ> I paste a bit of history

[19:22] <W1MXJ> Yes, hi! Is there a way I can talk to radiosonde enthusiasts in a way that isn't IRC? It's a bit frustrating that i can't see messages that were sent when I was offline.
[19:23] <W1MXJ> And it would also be nice to look back at advice I've gotten after-the-fact and such
[19:23] <W1MXJ> I was hoping to receive DFM17 20041959 but looks like no such luck
[19:25] <W1MXJ> Yesterday I recovered one of the sondes from near plainview (though not sure where their launch site is, can't find any info online regarding a site). Also got within 500m of 3 others, but had to abandon them since their final coordinates on landing (which i received) were in the middle of young cornfields
[19:29] <W1MXJ> Very interesting that the 28.8 mhz multiplies to right at 403.2, so maybe it's just bad luck that today's sonde was running on that frequency and not findable, oh well. Yesterday and today are relatively severe weather today, which is why all those sondes happened from Plainview
[19:30] <W1MXJ> Unfortunately in the middle of a moderately large city I think I'm being swamped out by FM broadcast stations, so I don't think I can operate a passive listening station
[19:30] <W1MXJ> Operating as a chase station worked great though yesterday!
[19:30] <PE2BZ> Radio Shack uesd to sell FM Trap´s which work quite well, you can even run 2 in series.

[19:33] <W1MXJ> Is it not a problem that it's a 75 ohm device with F-type connectors?
[19:33] <PE2BZ> maybe this is better
[19:33] <PE2BZ> shorturl.at/hqBJX
[19:34] <W1MXJ> I was thinking of going with https://www.ebay.com/itm/325179202313
[19:34] <PE2BZ> The rtl´s are all 75 ohm input :-)
[19:34] <PE2BZ> should work as well
[19:35] <PE2BZ> afk again.
[19:36] <W1MXJ> This says these are 50 ohm https://support.nooelec.com/hc/en-us/articles/360005805834-NESDR-Series
