Well, it was worth a try.
The RF Deck came out of a TKR 620 desk-top repeater. Unfortunately, the
front panel and other items were lost when the owner scrapped it out for
the power supply present in the Desk-Top repeater that the TK-722R came
out of; as well as the boards I described.
Sorry
Robin,
Thanks for that offer. I may be in touch with you on this in the near
future,
The repeater is set to go to it's final resting place (Permanent site)
this coming Saturday. At that point I will know for sure if the better
antenna/feedline will bring the balance I am looking for.

Here is an anecdotal solution to attenuation. A major tube
manufacturer's tech support once advised me to use a length of RG-174
balled up in a container between exciter and amplifier to calm things
down to a closer match to input power level...
I don't say this is the most scientific method,
I would also be interested in this.
Over the weekend, I picked up a VHF Engineering repeater that had the
CWID board removed to be used on the repeater that replaced it.

And they loose sensitivity rapidly above 48 MHz; even the CWB (Wideband)
models.
The 70-052C Syntech I was even spec'ed out to 54 MHz in the FCC database,
and it makes a great 6m rig. .3uV sensitivity easily attainable.
The 70-0520CWB Syntech II can be modified to get sensitivity of 3 uV.
What you will be looking for will most likely be a 70-0520CWB with the
70-2959-2 Vehicular Repeater Option.
All the ones I have seen listed on eBya have had the 70-2959-1 option.
I don't see any reason that UHF would not be a possible option as well.
The 70-0520CWB is the WidBand version (WB)
The option is 70-2959-x (where x is either a 1 for VHF (High Band) or 2 for
UHF).
This option was available in the 70-0500 series, which could include a

feature level, output power, etc. All 0500 series are Lowband.
