WAG (Worked All Germany) contest. I took some time and made 351 QSOs on 40m only and pure CW. I used the TS590s with about 80w of output. 41 DXCCs were contacted; so not bad at all for this very low installed dipole antenna.

Working all the DX throughout the past months was somewhat annoying when I wanted to make digital (JT65 or FT8) contact right after having switched on the transceiver, the Kenwood TS590s. This happens, when the main reference oscillator is cold and has to warm up for some time. I experienced a frequency drift of over 120 Hz on 50 MHz in the first 30 minutes or so. This is a lot.
The best solution would be to feed an external GPS referenced signal into the transceiver, but where to get this stabilized 15,6 MHz from?
So I came THE other solution of putting in a more stable oscillator in form of a Temperature Controlled Oscillator (TCXO).
There a an option (03) available, where you must buy an expensive temperature controlled oscillator for far over 100€ for the original Kenwood equipment. Nowadays there are quite cheap equivalent types available through eBay. They all seem to originate from China. Prices of those parts vary from 12€ to about 50€. I chose to order one for 19€ where I thought, I could do nothing wrong with it. Worst case: perhaps it would not work. After 12 days (30 days were proposed) it arrived and installation was easy.

With a stable beacon signal I could see, that the drift has been reduced to about 5 Hz after 60 minutes. That is a factor of 24 times better than with the old crystal. And the resulting frequency is only 2 Hz away from where it should be on 50 MHz. This makes this man happy now :-)

Today I decided to work on the antenna. My 2m transceiver (ICOM 820H) has a malfunction and it will take some time to repair it. The 9 element for 2m is thus not needed. I took it down and moved the 50 MHz antenna up by 1,50 m and added some guy wire on top of it. The result is, that the band seems cleanet and has much less noise - except direction west, where high noise stays and the source yet has to be located. The level of this almost white noise is about 15 dB.

This is the 6 element antenna for 50 MHz after moving up.

50 MHz
all: Experimenting with several digital modes like JT65 and MSK144 with very good results.

7 MHz
all: Working all continents with digital mode WSJT / JT65, 50 Watts and dipole antenna. Several new countries reached.

144 MHz
all: nothing, because transceiver has a fault, which I do not find, because it is intermittend.

Being very busy throughout the last months there was almost no time for anything else. Now as things slow down a bit, I hope to be active here a bit more ...
