[TenTec] Early Ten-Tec Service Note, SN-2-540, detailing Triton IV mod to eliminate RX/TX reed relay 'malfunctions' in earlier serial number rigs

[Jerry Volpe]

It seems like Triton IV (model 540) and model 544s are trading hands 
like hot potatoes these days. I suspect some of the new owners of the 
earlier versions of the Triton IV have obtained rigs that have weak or 
non-existent receive audio. This was a common complaint in 1976-. And 
even though logic said the problem is a 'bad' reed relay, in 99% of the 
cases it isn't a faulty relay but how it was used in the circuit... 
Anyway the weak or non-existent audio can be fixed with the addition of 
one 10k, 1/2 watt resistor (1/4 watt, heck 1/8 watt for that matter). 
Read the mod for details.

I was asked several questions by a new Triton IV owner. One of his 
problems related to weak receive audio. I remembered this mod from years 
ago and found it in my files. I retyped it for clarity. If you want a 
copy send me an email direct and I'll send along a compressed Microsoft 
Word document.

If your Triton IV has a serial number after 01749 or after T-1265 than 
you already have this modification installed from the factory.
