PI4GN i was guest operator 23cm
At early close Sunday 8 May log 60 QSO 23 cm mostly in CW
pitty just could not make it with the OE5 in the end the wind came up strong
summer weather in JO63ii 27C only just a week before we had snow.
13cm abt 15 Q 9cm 6cm 3 cm few QSO's
1.5cm was out of order after contest found a shortcut in the 144 cable
70cm about 170 QSO
Propagation and activity was low for a May contest.
Saturday night:
At 1296.240 MHz I managed a first contact after 25 years that I was QRT on 23cm
Got my old 23cm transverter back and on the workbench for test .
Connected to a IC706 at 144MHz
Very strong local contest station PI4GN about 15km distance came in 59
On a plugged in vertical rod 1meter a.g
55 report with about 2W .
Before I dared to TX i needed to make some protection for the SSB converter against the 144 drive signal. The 144 XVTR port I made on the IC706 did not have enough 144 drive power for the 23 TX mixer. So I used the normal ANT2 port at low power that is ca 600mW at 144
Picture cirquit showing 144MHz input relay with T/R switch PNP protection diodes over the 144 XVTR port
IC706 at L-power ca 600mW
