I imagine most may already have a way that works for them but I am just thinking of newer folks trying to build up some test equipment on a budget. This might help some on their benches with setting driver/final bias. Surely you can do it with a DMM but some might consider this to be...

Dan, just a report of some sad news. My ability to help out.... just got "knee capped"!!!!!!!! WHAT I HAD WORKING was..... IF you live IN Texas... you can pay about $24 a year for a remote library membership with the Austin Public Library that gets you in "online". THAT part still works...

It is still... in my humble opinion... goofy to have multiple part types with the same number. Do bear in mind..... I said I was getting WAY too old... ;)

I'm obviously WAY too old. How are you supposed to know "what part is what" when multiple SMD parts have the same marking??? I like old radios! ;)

Ahhhhhh!!!!! Did you join all of the same groups on there??? (BTW it was Steve Butler.... looking for SAMS for a Realistic TRC-431.... which I promptly sent him!!!! He was just concerned about you!) [edited to add] Here is the message he sent me... he did not say what group he tried to...

Dan, are you alive and kicking out there? I got a message from a friend on one of the FB forums who had sent you a request and has not heard from you. I'm thinking..... Christmas/New Year holidays.....you are taking some time way. But.... I thought I would let you know that "the world...

THanks much for the reply! I have always thought about using an old radio like that but figured that various finals might all be so "different" that ONE radio wouldn't work to test them all. I guess you are proving that this IS a viable way to test!!!!! Thanks.

Sadly, that one I do not. Apologies.

@danmcclain - there is an entry in the regular section where Claim Jumper is looking for the Robyn radio in CB-89. At the risk of stepping on toes (AGAIN!), I am going to plop it on here.... on the bet that THIS is what he is looking for!!!! 73 to you as always Dan.

That was easy! I started at the speaker ... traced backwards. When I got to the headphone jack on the front panel... it looked kind of funny. I put a finger in to straighten the wires a bit..... The shell of the headphone jack fell apart and the internal contacts fell out with the wires still...

Just curious.... can you test different part numbers? I mean... does that method work well enough to show whether the "test transistor" works.... even though the original 23 channel radio MAY NOT have used that part? ( I hope I am making sense...)

(just a "story".... not a "cry for help". I am having fun!!!) Well... since my layoff has led to my retirement I have decided to quit "eyeballing" that Console V way up on the top shelf. I actually recapped it about 4 years ago or so and just never got " a round tuit " when it came to...

Here is a pic of a clip. The clamp part clamps on to the rain gutter at the edge of the roof of your vehicle. What you do is pull the antenna down and stick the static ball through the hole then slide the actual whip up into the slot. When you do that... it is the BALL holding the whip in the...

Of course.... this will probably only work for small signal transistors... NOT finals and drivers.

A number of years ago, my "radio loving" son, Tim, snagged a 102" whip ... used ... from a friend of his... with ME IN MIND. It was mounted on my truck at the time with a ball mount and always worked really well. Actually did a little DX with it and the Grant XL (that got STOLEN out of that...

Expanding this in a slightly different direction... that MAY seem more like fantasy.... everything is heading towards SMD (surface mount). I have started eyballing these little "conversion boards" on Amazon. They are made with just enough surface mount printed circuit space to mount the...

Thank you so much. All I wanted to know was that he was alright. I wish him luck and good results in everything he does.

Has anybody heard from Handy Handy? I used to see his highly informative posts all the time. The last thing I can track from him is in like March or May of this year. Just checking out of concern.......

Dan, I hope I'm not irritating..... but I jumped on this one. Here you go.
