Hello Gerhard, thanks for the report, did you try to decode the RTTY ? 73, Rik ON7YD - OR7T Hello Rik, Your signal is fine visible on my waterfall, but with deep QSB-Phases. Vy 73 de Gerhard // DK6NI
Hello Jim, LF, indeed, class D amplifiers will (within reasonable limits) "adapt" to the load impedance. At least as long as the load is resistive. I have noticed that my PA (G3YXM design clone) reac
G0MRF now peaking 549 with lots of QSB But still in beacon mode ;-) 73, Rik ON7YD - OR7T Hello Jim, thanks for the info. I can hear the beacon CW on 503.1 with 429 report. Without QRN it would be a s
Gary, Gerhard, right now (20:35 UTC) I can see traces of my signal on the G3YXM grabber and strong signals from Gary. 73, Rik on the Hi Rik & Gerhard, When Rik makes his CQ call I will attempt to mak
Jim, Graham, MFSK4 seems to be good once you have it synchronized, as John (W1TAG) states. But the threshold to synchronize seems to be rather high. Despite the fact that you signal was audible and t
Hello Richard, if you let me know when / on what frequency you are transmitting I will try to copy your signal. 73, Rik ON7YD - OR7T Your beacon was quite strong the other night into Wallasey, 3 mile
Hello Gary, good copy. Did you play with the RX parameters ? What I gave was just the result of a 10 minute dry test, I can probably be improved. Any chance for a RTTY QSO one of these days ? 73, Rik
Hello Jim, thanks for the info. I can hear the beacon CW on 503.1 with 429 report. Without QRN it would be a solid copy. 73, Rik Dear Rik, LF Group, At the moment (2030utc), they are transmitting a C
Graham, 21:15 UTC Throbx2 = 80% copy PSK31 = 50% copy MFSK4 = 0% copy (although audible weak) 73, Rik Ok Rik, Well see what prints with this beacon, Im running Fldigi x 3 times on the same pc , Gary
Gary, my signal is now even gone on the YXM grabber. Poor propagation tonight. I am going QRT now. 73, Rik ON7YD - OR7T Rik, You signal not as strong tonight so far. Gary. --Original Message-- From:
Hello Gerhard, I will do a last transmission at 22:00 UTC Otherwise we can try tomorrow (WX permitting) 73, Rik Hello Rik, I have just installed MMTTY and playing with the settings and need one more
Mal, depends on what you expect from it. At the Twente university the WEBSDR covers 8 frequency bands each 600kHz wide (ham bands from 1.8MHz up to 21MHz plus DC-600kHz) with a single ADC fed by a si
Jim, tonight my antenna is disconnected because of the thunder and lightning show above our heads. I copied your beacon last night 529. 73, Rik ON7YD - OR7T Dear LF Group, As art of continuing invest
Hello Alan, thanks for the info. What I had in mind was a 501-504kHz filter so not as narrow as the 800Hz filter you designed. And as an input filter I wouldn't care about 10dB (or even more) inserti
Hello Richard, all, I did some 500kHz tests last night with the Twente websdr: - I cannot hear or see my own signal on the websdr (abt. 1W ERP, distance 200km) - While I heard G3KEV 599+ here I could
Hello Alberto, it is just out of curiosity what can be heard by such a system (feed the antenna signal into an ADC and let some software do the rest). On LF there is more that MW broadcast. Around 40
Jim, I heard Chris working you, but nothing at all from you (not even traces on the Argo screen). Chris was 559 here, so your ERP must have been at least 15dB below that of G3XIZ. 73, Rik ON7YD - OR7
