F1DQM
DB-1500 amplifier for F1DQM
DB-1500

Test 

03-10-2017

TRX = IC-738, Power 15W, Amplifier : DB-1500 (F1DQM )

With 15W by TRX,the P.E.P. OUTPUT is about 500-700 W

*** QSO with UB4WAT : SSB -14148 kHz, very poor propagation and my ant : HEX BEAM was not direct to him - was direct to NW EUROPE ***
