Re: PD526 Duplexer Tuning
I measured the cable lengths and it's rg214 and it's approx 11.5 in for

Re: PD526 Duplexer Tuning
You got the cables from me, and they are decidedly the correct cables. The four 11.5¡± cables go between cavities, the 12¡± cables go to the triple-female tee that I sent.

Re: TKR-850 No Receive
Just in case you are not a vet with the 850, is there a molex plug in the connector under the transmit coax connector?
On my Kenwoods it has to be there with 2 pins jumpered for the speaker to work.

Re: TKR-850 No Receive

A DB 201 or 212 is the best on lowband...there are a lot left abandoned at
