2010/1/27 Rik Strobbe <[email protected]> Gary, solid copy here, SNR -5 to -7dB. But the signal is clearly audible, CW would be armchair copy. Any idea down to what SNR values JT4A produ
Will do! I am getting several decodes of your “G4WGT QRZ” call all at around -15dB. There is another occasional signal on evens but not decoding I am running 10W from ICOM 706 mk2G into i
Gary, the SNR values over the last hour or so varied between -2 and -13dB. Assuming a -24dB limit and your current power (50W) anything above 5W would provide solid copy and 0.5W occasional copy. Imp
Hi Gary Just got two decodes of you at -12dB and -15dB 2116 and 2118. I have replied with my call and locator on odd minute txing With best regards Jim Dr. James Cowburn E blocked::mailto:james.cowbu
Thnx Rik, there’s not much between me and you though, just the east England fens and then the north sea!! Jim, you are good copy here (-18dB). 73, Rik ON7YD - OR7T Van: owner-rsgb_lf_group@blac
I was looking at driving push-pull transmitters from fundamental drive signals quite recently. How about a frequency doubler? The output doesn't have to have 1:1 mark-space ratio as it only cl
Gary, solid copy here, SNR -5 to -7dB. But the signal is clearly audible, CW would be armchair copy. Any idea down to what SNR values JT4A produces a usable decoding ? 73, Rik ON7YD - OR7T Van: owner
VERY TRUE.......... One solution for narrow band would them be to filter the output to remove the fundamental (and any other odd order) componets that cause the asymetry Andy www.g4jnt.com This ema

Andy, Rik Been running a doubler for WSPR at WE2XGR/2 for the past couple weeks. Linear exciter > doubler > push pull Class D amplifier. So far I've tested it on WSPR, MFSK, Domino EX, Thor, Olivia a
Jim How do u get 10w out from the 706 on 500 kcs. I can only get a couple of volts into a 50ohm load mal/g3kiev -- Original Message -- From: [email protected] James Cowburn To: rsgb_lf_group@b
-24dB S/N (2.5kHz ) is usually guaranteed Andy www.g4jnt.com This email has been scanned for damaging side-effects by the health and safety police, is guaranteed to contain no substances hazardous t
Andy, such a doubler will work but the flip-flop is not a guarantee for a perfect 50/50 square wave in this case. The flip-flop will be clocked by both edges of *one* of the XOR input signals, which
