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
Peter always a super video truly well done and very professional and I learn so much. I am so grateful and in debt to your kindness and willing to share this Great enjoyable time well spent' I really owe you so much. God bless you,
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 :-)
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 !!
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…
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
Brilliant chap love his videos
Hi Peter: Another excellent repair, Sinad meters are still available in both kit and built versions at a pretty reasonable price. Andy
Always brilliant and effective fault finding, with analytical information and explanation. Thank you very much Sir!!
Thank you Peter!
Thank you
Very nice repair Peter, nice to see all troubleshooting. Thanks for sharing my dear friend, 73s de IW0HEX Pasquale
Thank you, my dear friend!
Nice repair. Thanks for sharing Peter.
Nice repair. Always love your explanations and detail. The glare in the meter wasn't that bad it was still able to see it.

Thank you
Way above my head, but brilliant work. Well done. I am happier with old valve technology!
Once again great method and practice. Great work
Great repair as usual and we learn from you. Thanks for sharing.
Thank you
I enjoyed the video, thanks for taking the time to make them. David, N5GEB

Immer wieder spannend zu sehen, wie solche Probleme gelöst werden. Danke für deine Videos!

Danke für das Lob!
How nice it is to have parts at hand! Hard to explain to my wife tho...
Hi Peter thanks once again for your detail repair well explained trust your family are all well
Thank you all fine
It's nice to have an easy one for a change! Nicely done 🙂

Nice work peter !
Wie immer ein Genuss. Herrlich. 👍
Danke sehr
Immer wieder sehr interessant deine Videos! Top!!! Weiter so

Veey nicely done.. thaks for sharing
good repair
Good to see you Dennis!
Always enjoy a gravy job. 😂

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

A passive probe 50Ohm 20dB attenuation...
What probe make and model? Please
I have just received one of those Ukrainian probes, built it into a metal tube. Its incredibly sensitive G4VQH
Hi Peter, what kind of probes do you use with your DCA75? They look handy.
IC microclips
@@TRXLab Thanks Peter! I really enjoy your repair video's.
IC-9100 doesn't have pre amps for 2M, 70cm & 23cm so it should be a bit deaf.
not having a pre amp does not automatically mean the radio is a bit deaf.
Das Problem, beim Fehlen eines R&S-Messplatzes, ist das korrekte Messen des SINAD. 😢
mit nem AC Milivoltmeter + Filter sollte es gehen..
@@FUNKLABOR_DL1LEP Im Prinzip ja, aber umständlich und wahrscheinlich nicht sehr genau. Gruß Karl.

Ich glaube, das ist nie ein Bausatz geworden, da vermutlich der gewünschte Absatz dieses Gerätes nicht erreicht worden wäre, schade...
Es gab damals auf dem Markt ein sogenanntes SINADDER www.repeater-builder.com/test-equipment/helper/pdfs/sinadder-1.pdf
shame he is deaf
jedes Video ist eine große Freude für mich !!! 73 de DL6RDE / AA1KD, Charlie
Das freut mich wirklich Danke Charlie!
