Results of the Storm Eberhard...

There were a lot of storms... We lost TOP band vertical last year etc. But this was maybe the strongest one ever at OL7M QTH. Most of rotary antennas is shifted on the pipes... Usually, the strongest winds come from 300 deg. So "parking" position for the antenas is to NA. That Eberhard was different. It looks on W or SW wind. The antenns: 5el for 20m is shifted by 40 deg, 6el for 15m the same, bottom 6el for 15m has broken M8 screw on the linear motor and the two top antennas in the new stacks are demaged... So a lot of work on old antennas instead of new towers and antennas :( Thats live :)

Wind! We hate you! :(

There are the results of the whirlwind called Eberhard...

The TOP two antennas in our new stack for 15/20m are for RIP = Rust in Peace (OK2RZ JdC).
Also our fireplace and 6 el Yagi for 10m...

10 GHz LNB with PLL and TCXO, Bias Tee, part II.

   Very simply modification of LNB with PLL and 25 MHz X-tal. With 1 ppm TCXO there is nice 10 GHz RX for tropo and satellite. You need only some SDR receiver.


   Bias tee board allows you to supply LNB over the coax. It also includes high current and voltage protections as well the variable ATT. You can easily set "gain" of LNB as you need. Recommended power supply is +12 V and some 100 mA.

More info about TCXO modification is there...

You can ask for price on my email: honza at or shop on ebay.
