Gary, despite that there is no copy in MFSK4 this signal sound much stronger than the Throbx2 and psk31 signals. Idem on the G3YXM grabber: MFSK4 look brighter than the other 2. Looks as if the power
I noticed. Last night I could see it on all 3 UK grabbers, tonight only faint traces on at YXM 73, Rik Rik, You signal not as strong tonight so far. Gary. --Original Message-- From: owner-rsgb_lf_gro
Hi Warren, depends on what you call a neighbour. In the early days of 136kHz I worked stations up to 400km under similar conditions. 73, Rik ON7YD - OR7T Tnx Laurence, If he's running 25W into a 25m
Hello Gary, LF, I just had a first transmission. I will try short transmissions every 10-15 minutes or so until my signal shows up un your grabber. Then I will start longer transmissions. 73, Rik ON7
Hello Gary, I had a closer look at the 23Hz shift option of MMTTY and it seems to run at 45Bd what is on the edge regarding the shift/baudrate ratio. That is most likely the reason why it is not so r
Gary, LF, I just had a look at MMTTY and it seems pretty easy to set it to 50Hz shift and 22Bd baudrate. The way I did it: 1. As a start select 23Hz RTTY (in "Profiles") 2. In "Options" select "Setup
Gary, a simple series L-C notch works best when - Q is high = you need a good coil (capacitor Q shouldn't be the problem) - the output "sees" a high impedance (FET buffer) - the source impedance is h
Hello Gerhard, tonight I will call CQ on 503.5kHz starting 20:30 til 21:20 every 10 minutes. Same mode as yesterday. 73, Rik ON7YD - OR7T Hello Rik, Sorry, but wasn't able to answer earlier. Well act
Hello Richard, is you antenna matched to 50 Ohm ? If you just bring it to resonance (loading coild adjustment) the antenna impedance can be anything between 10 and 100 Ohm. And some 10m's length of c
Faint traces of my signal are showing up on the G4WGT grabber. I will transmit every 10 minutes starting 20:40 UTC until 21:30 UTC and listen inbetween. 73, Rik ON7YD - OR7T Hello Gary, LF, I just ha
nil from G0MRF here (until 19:30 UTC) Are they QRV ? 73, Rik ON7YD - OR7T Dear LF Group, Just worked G0MRF at 1705utc. Signal was 549 - apparently they are still working on the antenna, so might impr
I will have a look for you. Good Luck Rik if you let me know when / on what frequency you are transmitting I will try to copy your signal. Rik I hope to be QRV at 1330z today portable from IO83xd. 20
Hello Graham, thanks for the QSO's last night. Under current conditions (lot of QRN and QSB) ThrobX2 seemes a bit better than PSK31. MFSK4 wouldn't print last night. The night before it was the same
Gus, Dave, Graham, I guess even the Q of the antenna can attenuate the low and/or high tones. In theory with a SSB bandwidth of 2.7kHz and a operating frequency of 505kHz a Q = 180 would cause a 3 dB
Dear all, confronted with the seasonal rise of the loss resistance of my 500kHz antenna (from 35 Ohm in winter to 80 Ohm in summer) I would eventually consider to try a loop antenna. Dimensions of th
Hello Gerhard, LF, thanks for the report. I just finished a transverter + linear PA and it was one of the first on-air tests. Transverter: 4.5MHz to 500kHz with 4MHz xtal osc + SBL1 mixer + buffer am
Hello Gerhard, thanks for the report. MultiPsk can receive (and transmit) FM-Hell At 21:20 UTC I will change from FM-Hell to RTTY (50Hz shift / 23Bd as last night). 73, Rik ON7YD - OR7T Hello Rik, ni
Warren, I guess this problem can be solved by removing the onboard xtal and injecting a signal from a stable frequency source. 73, Rik ON7YD - OR7T This is EXACTLY the dds that I used and observed co
Hello Gerhard, propagation seems to be better than last night. But also strong QRN. I could see most off my FM-Hell and the 21:20 UTC RTTY transmission clearly on the G4WGT grabber. I had last RTTY t
