Board Manufacturing

One Key Feature is to mill boards.
This always is a new adventure but is the only way to keep the flexibility, e.g. to change VCOs, MMIC or Reference Oscillators.
Currently around 15 different Versions exists.

27MHz PLL for 10GHz LNB
Messplatz Application: Low cost TVSat LNB disciplined to 10MHz reference
Using commercial TVSat LNBs to receive signals in the 10GHz radioamateur segment is nothing new. Since new PLL based LNBs were launched to market to fit the HD needs for better stability they proved to be useful for Rx of narrow signals like CW and SSB. Size, price and sensibility of this devices are unbeatable. But one problem is that they use a simple quartz crystal as internal PLL reference,so the long term stability is poor. Temperature variations when operating outdoor make it drift slowly and constantly. One never knows exactly which is the frequency tuned in a received signal
Finally we can say that this problem has an easy and economic fix.
Solution is a 27MHz PLL disciplined with a 10MHz reference
Stability and precision will be as good as the 10Mhz Reference used.
