Re-acivation of old 10GHz
beacon DB0ZDF in JN49cx
From 01/04/2012 to 23/06/2012 ;QRT since Jan.2017
Guenter, DF4PV asked
me in April 2012 if I have interest to renew with him the old 10GHz beacon
DB0ZDF on the television building of ZDF in Mainz, JN49cx. Sure I had and so we
start working on it in May 2012. Guenter bought the Waveguid antenna and cleaned the box and I changed the
beacon keyer against a new one based on PIC controller.
The new crystal is still on the way to us… Hope to get it soon so Guenter can install the beacon on his final location in
J49cx. QRG will be about 10368865.0 +/- 20KHz…
