I found this swing mod for another make of radio that puts a resistor and cap in the power supply line to the driver, I'm thinking I might give it a shot. if its the line from the AM AMC. Any thoughts on this mod if it might work for my issue? thanks again.

Thanks guys... I've been to that page. That's actually how I found this forum in the first place. I did the mod you mentioned plus the double diode on the limiter (D20 I believe). I have the radio dead keying 4 watts from his suggestions but I need it to dead key from 1 watt up to 12 or 16 or...

I have a TRC-457 dead keys 4 and swings to 8 on a peak meter, I need to set the dead key at 1 watt and let it swing to its full potential. can anybody give me a rough idea how I might go about this or a link to where I could get instructions on how to do it. Any parts required and so on. Thanks.

I know this thread is 10 years old but I'm wondering if you still have the radio and did you get it working? and I have a couple of questions about the power cords system on that radio...I assume the problem that you described would be a leaking capacitior

Hey folks, I acquired a Jo Gunn Skip Jack a while back that has never been set up yet, The guy that gave it to me cant find the gamma bar and instructions for it. I found the instructions on the internet but I still need a Gamma bar. I have a few kicking around from some scrap antennas so need...

I found out the hard way about full strength Simple green, took the silk screen off a turner plus three I picked up in an estate sale. Ill have to find a silk screen place now I guess. Anybody know any good ones that cater to radio people?

I recently purchased some used radio's and the finish looks like it is good shape under the years of dirt that has accumulated on the knobs and face plate, what is a safe cleaner that wont scratch the chrome finish or remove any of the lettering? thanks in advance for your suggestions.

I'm flying out on Tuesday but I should get there this fall for sure. the guy I bought it off used to run a pdl2 a swell and is kicking himself for getting rid of it. If I have success with mine I will build him one as well, first I'm going to buy a good antenna analyzer to save me 50 trips up a...

I replied to an add about a Maco 5 element on kijiji and he said he has a super scanner that has been in the air for only a year, I saw pics and its immaculate, so I bought both of them. Its still on his tower. I'm going to clone it once I get it and if the clone works as good then ill sell the...

I used to use a regular 35 watt iron but now I'm getting back in to the tinkering hobby, I realize I should be using an isolated or ceramic iron, I only see the Hakko 600 on Ebay from Japan, is this a reliable unit or should I look else where? Are all soldering stations isolated or do I have to...
