307,
I wanted to know what is the deal with the Cobra 146 GTL? I can't do anything to it. I have it deadkeying 26 watts on AM and 30+ on SSB, the ears are real good but I can't hook up echo, rodger beeps, talk back or a power mic.
My second question is, I want to turn the audio up on my TRC-440. I have been told to cut the D107 or the D108 wire. Which is it? wanted to know before I messed something up. Can't I just turn the two tunning pods to turn it up and if so what are there #'s?? what is the best way to hook up talkback on the TRC-440? what size resister do I need? thanks for the help. |

Inklink,
Tune up for the TRC-440 is:
CUT: D107 OR D108 (means either one)
ADJUST: L102, L104, L106
You will need a 100 ohm resistor either 1/4 or 1/2
I hope this will help you a little. |

I'm curious to know how you are getting a 26 watt "deadkey" from a (2sc1969) 18 watt final. Do you mean that you are "swinging" to 26 watts on AM or are you actually dead-keying 26 watts. The reason why I am asking is because a 26 watt AM dead-key carrier = zero AM modulation!! |

I have one it has a 2sc2312c final in it,pretty close to the same;some one could have tricked it out with a matched pair,or one more powerful and detuned it for longevity.Sometimes people don't list all the mod info.and this get's them in trouble,there's many,many posts like that. |

You're probably right BB. I have seen it myself before. But in this case I thought the SSB power was way high also for it being a single final radio. But, that's what I get for ASSuming again.

This radio has been tricked out. It has bigger finals and alot of other things done to it. Alot of what has been done to it I don't understand but my tech spent alot of time on it. I use it as one of my base radio's and it talks and receives better than my big base radio. Didn't mean to confuse ya'll. I just know what the tech told me. Like I said half the stuff he did to it I couldn't even start explaining. All I know is this radio is a keeper and I will never part with it. Just wish I could get talkback in it. lol
73"s to every one.

I could be wrong but if memory serves me correctly, the early Cobra 146 and Uniden PC-122 had the same board in them. A few weeks ago, I think someone had asked about a Talkback in a PC-122.
Go to the left of your screen and click on "Keyword" and then type in 146, or PC122, or if all else fails, just type in the word Talkback.
I hope this may help you. If not, then maybe someone else can.
