Hi All - Just switched on the receiver and copied a short burst of "poetic" RTTY on about 503 kHz. Decoder settigs were 45 Baud, 170 Hz shift. No callsign or other id - anyone else copy it? Brian (G3
Hi David - I'm getting half a microvolt from your beacon using a 3 turn loop with area of one square metre. I figure that works out at 17 microvolts per metre field strength. I'm 23 km due north of y
Hi Gary - Copied part of your RTTY CQ on 502 kHz (1855 ish) - about 50% copy. I could see your signals in the noise on the waterfall but only decodeable on QSB peaks. Did you see anything of my repli
Hi Malcom - I've got the necessary kit for PSK31 on 500 kHz (25 watts pep linear) and hope to have it back in working order next month. QTH is Watford. 73 Brian (G3YKB) -- On Mon, 15/9/08, Malcolm Ha
It may not be absolutely what you are seeking, but look at the website of W9CF. He has a prog for converting admittance to impedance based on reading from a General Radio GR821. 73 Robert Smith Chart
Hi Rik, Marco, Andy and any others who asked about the ts850 mod The info came from Bob Vernall ZL2VCA http://we0h.us/Amateur_Radio_stuff/TS850/ts_850_lf_tx_mod.pdf and yes, it does seem to fool the
signal. I see that Chris G3XVL often reports a +13dB s/n ratio for Jim's signal, which shows that strong signals can decode correctly. The question of brevity in passing information (ie "having a QSO
Hi Graham - Make that 4! I've modified my TS850 to generate SSB at 500 kHz and use a homebrew linear PA to produce 30 watts peak RF. Have been off air for a while during a shack rebuild and broken ae
Hi Petr - I use the TDA2030 as a pre-amplifier to produce a few watts in my 136 kHz linear PA. The spec implies that it should still have some useful gain at 500 kHz - I'll be most interested to hear
Hi Daniele - I'm very pleased with the Kenwood TS850 - it cost £400 but it means I now have a spare HF transceiver. It is sensitive up to 504 kHz without modification (and all the way to 30 MHz with
Hi Andy - I got one decode this morning here in Watford (-15 dB at 1042) but I did not realise it was you (G8IMR) Brian (G3YKB) -- On Sun, 19/9/10, Andy Talbot <[email protected]> wrote: From
Hi John - I'm seeing a 5dB increase in the "noise floor" between 498 and 502 kHz but only after dark (measurement taken at 2300 utc). Location is Watford (IO91TP). Receiver is Winrad Excalibur SDR. B
Hi Alan - many thanks for the report - you're my best Dx report on LF so far..... Apart from the PSK31 I've also loaded up the software for the faster Jason and MSK08/31 so will be trying them out on
Hi Wolf Yes, I would like to try a sked - I could transmit at 1100 or 1200 UTC to-morrow (Thursday 6th) or Friday (7th) and possibly Sunday. I did get some copy from your PSK08 QSO with Jim (M0MBU) a
