I will now mount a bigger heatsink, 2 fans and a case and then I will do some more measurements. In addition, specific models mentioned in the RF linear amplifier forums, Like. While in the QSO I pushed 5W from the 817 into the amp and with 3 SWR-bars on the dispay and 74W output I killed another pair of IRF530N mosfets. Here, youll find links for high power RF linear amplifier covering hf-vhf-uhf. Numbers indicates the output and the numbers in brackets are "SWR-bars" on the FT-817 display: InputĪfter the "measurements" I was able to work S57DX on 20m with 60W output (2,5W drive from the FT-817) and I also worked my friend Peter, DC2ZO. The R&SVK3150 150 W HF power amplifier increases the HF output power of the R&SMR300xH/U manpack radios to 150 W PEP or 100 W average. I did some power output and SWR measurements then.
