RCA CO-PILOT 14T304 help and alignment info

[KD2GOE]

Guy gave me a RCA CO-PILOT 14T304 it works but I had to rewire the mic plug to the standard Cobra 4 pin

it took me a min but some one did upper Channels on the ANL switch and I am going to reverse it to normal as I see it having no point at every one is using SSB up there

ok but I am getting 4 watts from Ch11-40 and 0 watts on ch 1-10 I am picking up some contact cleaner tomorrow at work to spray if that don't work where can I start looking to fix this?

and where can I fined alignment info?

here is the service manual for this radio. it has the 02a PLL and you can easily put lower channels in it since this pll is easy to do. on AQM lowers isw what is used. more than likely you have a power balance issue and the service manual shoul help you find the problem.

RCA 14T260, 14T270, 14t303, 14T304, 14T305

also here is a link for the PLL mods. .will help you reverse the mod.

I had it on the freq counter and I am getting NO TX Freq read out from Ch 1-10

I hope the PLL is not busted {Cry_river}

Check alignment of the VCO coil.

if the vco is not locking on in the lower channels this will happen. just look at the manual and check the internal adjustments to see if some there is out just a little. will lead you to what might be wrong also.
