Remembering of course that a PURC station was designed for PAGING service...
If you have ever had to set levels in a paging or fire dispatch system that
used the very low end tones just above the PL range you know real fast why
the flat audio board was created.

There is a big difference between the Micor or Mastr II station that was
factory built for a specific frequency or group of frequencies and an
inexpensive mass marketed radio that is built by the thousands on a
production line.
Same thing as what a paging system operator told me about an early

Glad to be of help! I have some UHF 5PPM 1088A's which also work in the VHF

each plus a token amount for shipping, if you're interested.

Oh, and one last comment, most every Amateur Radio potable is unable
to do split Tone PL's. One Tone PL for TX and another Tone PL for RX.
I don't know why that is so. It would just take a little extra code
writing, but what do we expect, It's Amateur Radio Grade Equipment.

Gentlemen,
Is LMR-400 a good coax to use for my 70cm repeater feedline. My
feedline is 130 feet long and located at my house. Should I really go
to hardline and replace my LMR-400 feedline? If so what diameter?
Will it really be worth the cost and trouble to run it through my

Save yourself some grief and keep all LMR cable out of any of your repeater
installation.

Re the LMR-400 coax: No, due to dissimilar-metal issues. Use RG-142B/U or
RG-400/U for in-cabinet wiring.
Re the Daiwa: No, due to potential IMD and losses in the UHF (gasp!)

Re the Diamond antenna: No, due to quality difference between it and a

Bob,
I have two DR-605T radios, and both have one pot, VR204, which adjusts the
combined voice plus tone levels going to the modulator. It is not possible
to adjust the CTCSS tone level independently. However, I padded down the
tone levels, upstream of this pot, on both radios to about 600 Hz
