QRV 23cm/ 1296 MHz again after 30 years....

Image
"mast head" placed close behind 1m2 dish in plastic box (ACTION 1€50)  XVTR  1.5W , PLL 1150 DF9NP ,   PA PE1CMO  30-40W rF ( hoping) pre-amp  SPF5189z eBay  lowered to 2V7 still draws 160mA ! I replaced the original SPF5189z because it almost looked like short circuit  at 5V an UA78L05 could not supply it! needed a UA7805 200mA+  PCB heath up  need a better quality SMA - N  adapter   first QSO with  local PA0T very loud 9++  After 30 years  back on 23
                                          yesterday evening in nice temperature and no wind finally.
 A good time to place the disc + XVTR up
The modified DB6NT with PLL 1050MHz l.o. that was prepared last year up in the mast for the real test.
In JO33HG  could copy  4 beacons reasonable almost 100%
419  to 539   QSB flutter Airplane reflections
1296.930   OZ7IGY  JO55wm   to 529
1296.920   DB0VC   JO54if       519
