120Watt VHF Amp & Adjustment of BIAS - 87-108 Mhz -

Just for a bit of fun here is a little follow on video from my 100 watt amp build.... I never showed how to set up the amp on the original video... so here it is and also testing the NRG PLL PRO 3 with an amp. The TX is one watt output/Drive.

Thank you to all my subscribers

I'm curious why you used a fixed voltage for the gate bias - the data sheet designs I've seen point to setting the bias for an IDQ of 100 mA. If you just use a fixed voltage, there's no correcting for unit-to-unit variation in the gate threshold voltage.

Hello! Great youtube content. A question: Why do have use two watt meter devices?

Very helpful tip/video. Just finished the same linear amp so I will try this before connecting the LDMOS. What realy puzzled me is the heatsink size. Is that size enough for a 100% duty cycle on 100watts?

Thinking about putting different mosfets in my little kl203p for 11m! Running into problems identifying the mosfits as a lot of the numbers are sanded off! What mosfits would you recommend I replace the factory ones with? I have some irfz24n's but they look the exact same as the factory ones with the numbers sanded off!🙈
