Hello all, In order to test my 136kHz TX at home, I just have installed a toploaded wire in the backgarden. It measured only 135pF, which is too low, because need around 10mH to get that running on 1
I really don't know what's happening Viktor. Yes, I run more power than yesterday, but only 1-1.5dB more or so. Antenna current is just a little bit more. I can crank up the power by another 3-4dB...
Hello all, I plan to run a test transmission at full power coming saturday, if weather permits. Frequency: 136.550 kHz +/-50Hz in CW, about 8 wpm Time: 14.00 to 15.00 utc (16-17 local time) if everyt
Well, thanks all for reporting my signals on 137.7 I switched off now at 10 ut after 3 hours non stop operation. (longest sofar) Nothing went bang, James! Everything works fine; no extreme heat or wh
Hello all, I am happy!!! I just made my first QRSS/DFCW QSO's by accident. I just wanted to check receiving software, at the time running 'spectrum laboratory v2.1 b2". I connected the T-antenna to t
Thanks Dave, I am interested to see the difference between my signal, and those from other PA's. Victor is about 85km to the west from me, so closer to the UK. Compaired to yesterday I'm now running
Hello all, I'm running into problems when trying to make DFCW with ON7YD's programm. In this mode it seems that the RTS port has a signal (key in QRSS) and the DTR port (normally ptt) has a signal. I
Thanks Alan for the suggestion. Well while tuning the variometer everything seemed working as it should be. The SWR nice dropped to zero, while the antennacurrent raised. With help of a separate rece
I thouht to have seen a PLL design by IK2PII or an other I-station for 136kHz which uses rather simple components. Unfortunatly I lost the schematic, and can't find it back on internet either. Anyone
First off all the power this afternoon turned out to be 250Watt output. Maenwhile I completly rebuild the output coil and switch of the transmitter, and now I'm able to switch between 220W and 530 Wa
Well , the tuning is rahter sharp.... I think a possible source of trouble might be the antenna current meter itself. It is rather close to the loading coil. I'm using a metal (!) tube from an old su
For those who didn't know, use following 'trick' to tune your own X-tal. (found it in a magazine from the VERON) Remove the metalcover and place the remains in an oscillator. Now it will oscillate on
Hello, Last message from home before leaving to LX tonight. As mentioned earlier we try to have the station running on all bands at 18 ut, or a bit before. Situation for 136kHz is rather 'unexpectabl
Hello all, 2 days to go........ We will have an online log available, but the loggingprogramme (N1MM) can't handle 136kHz (yet) Therefore 136kHz QSO's will be logged on 50.136kHz Therefore you will f
