Afternoon,
Maybe someone with more knowledge than me can help, I am looking for a dual trace analog Oscilloscope to use on my Yaesu ft-102 radio's for repair work. I would like to learn all i can about repairing and aligning them, Was hoping someone could tell me a good brand name and how many mhz the Oscilloscope should have. In order to be able to use it on my ft-102 radio's. The help is greatly appreciated 73,

Anything 50-150 MHz would be more than enough to sample and examine HF, and a little above depending on how high you want to go into VHF.
Solid State of course (y)
That's my suggestion anyway, you could get-by with less but it's always nice to have room to grow.

You have to consider most people use FM on vhf. Few SSB ops and even fewer on AM.

I am just looking for something that will allow me to troubleshoot problems with my Yaesu ft-102 Transceivers, And want to make sure i am buying the right oscilloscope for the job,

If you are going to get into ham radio as an operator go for the best scope you can afford with out taking food off of the table. For the frequency range of the FT-102 a
60 MHz scope would be plenty good. You don't really need to see the cycle by cycle of the output of the finals. The scope would be used for peaking and dipping certain signals during an alignment process. A dip would be the carrier suppression during the SSB alignment. I don't know if you have one but a Laboratory grade frequency counter is great to have. You can read the frequency from the oscilloscope but unless it calibrated it is a waste of time.

I use a tek 7603 with two 7a29 vertical amplifier plug ins with a 7b80 time base. Does everything I need it to too. The cool thing with the 7603 along with some others is that is has the plug ins. So, if one wants to delve off into testing something else, plug-ins can be had for those testing purposes as well. They are getting old though.

    Hello I have a old school 2950 receives great on all modes and transmits great on AM but no transmit on SSB. Does anyone have any idea?
