Nice repair. Always love your explanations and detail. The glare in the meter wasn't that bad it was still able to see it. 73

Hi Peter: Another excellent repair, Sinad meters are still available in both kit and built versions at a pretty reasonable price. Andy

It's nice to have an easy one for a change! Nicely done 🙂

This repair actually looked easier than it really was. Because of the FET short gate to source, we had a lot of impedance mismatch. This makes it difficult for you to interpret the measurement results... On video, you saw the short version :-)

I would like to see at the end of the video that 20db gain between the input and output of the transistor in the spectrum analyzer. As always, great video quality and an explanation from the teacher

Blessed love my brother, great video as usual bro, Can you repair a radio for me, I am from Jamaica west Indies, Can you let me know very soon, can i get like a number for you so i can talk to you direct, please an thanks !!

@agvr5653 7 ай бұрын

Excellent as always, thank you….one question : the fact that only VHF was affected by the Fet failure means that UhF and 1200 were using different Fets ? Being certified up to 2/2.5 GHz I thought that all three band were using the same amplifier section…

@TRXLab 7 ай бұрын

Thank you. This radio has 3 different receivers for the 3 bands

Hi Peter, do you use an active probe for the SA?… i have troubles on some RF circuits do to capacitance of probe changing the tuning of RF transformers! Have just ordered a cheap Ukrainian active probe to help sort problem. Would appreciate your advice. Another great repair video, I am learning much from these 👏

@@karlbesser1696 doch, genau messen kann man das schon auf diese Art, das macht ja ein CMT oder CMS auch nicht anders, schade, daß es das SinadMessgerät als Bausatz beim Funkamateur(oder war es DARC) nicht mehr gibt, da müsste mal was äuquivalentes her.. 73
