Portable QO-100 setup

While I wait for the 20W Amp...

40cm dish. Modified Starcom SR-3602ACE twin LNB
I found this LNB to be the most sensitive and great for the purpose.


Works great.
100nF capacitor without removing the 25MHz crystal.
Then I feed stabilized frequency from mini Leo Bodnar.


POTY Patch Of The Year...


200mAh on receive for the SG-Labs transverter


1.03 Ah on TX


1W from FT-817nd. Probably to be adjusted down when PA is added. 
2 green led’s on the transverter is good! 😊
432.045 - 432.295 gives 2400.50 - 2400.300
432.190 in is roughly 10.489689GHz down

Good antennas and Analyzer...

This antenna can make a good uplink antenna for Es’hail-2 satellit at 2400 MHz


Very good patch antenna.
For 13cm it is ready to go.
For 3cm, I need an downconverter to 70cm.




My new rig?


Making the LNB ready for POTY antenna.
Modification needed for GPS stabilized frequency.


One version of it should be with tcxo.
Adjusted for 432MHz

Working WSJT-X

It's impressive that any stations are heard through the noise..

We found 3 sources of noise at the local neighbour.
3 zones of downlight spots in their basement.
1 zone with about 8 spots in it is the worse one. There is one spot gone bad, so if we are lucky it is the driver for the bad spot which makes the noise.

So, the neighbour will come back to me - hopefully we can solve this issue.

5m more up in the air


6-meter antenna
5el 50-ohm 8.5 dBd pointed 180° 5° elevation


But noisy conditions from neighbours... :-(
I have 3 sources of noise. It is 50Hz noise, so probably a gas light starter x 2











Makes it impossible to work weak-signals from scatters or the moon..
