Hello folks.
I'm in need of at least five CTCSS decoders for a repeater project.
Preference is TS-32 or -64 as I'm familiar with them but any other model
proven to function well works too. Prefer to have all the same model.
Contact me directly via email.

Yes I have done a goggle search and most of what pops up are simplex
repeaters and cross band repeaters and photo's of ht repeater boxes
but no circuit diagrams.

An 805 WILL NOT do trunking. only conventional. The 840 wil do both.

Does anyone on here have or know where I can get a copy of the old Decibel PatPlot software that was available on their website years ago. Can't find a copy anywhere and it would be nice to have so I can test antenna patterns on the computer versus in the air on the tower.. Andrews website does
Dave,
Keep in mind that the Midland 13-509 was built for the Amateur Radio market,
and the transmit crystals are only specified to maintain .001%, which is 10
PPM. There is no temperature compensation in the crystal circuit, and you
may make the drift worse by using an NPO capacitor. If you

I bought a used 220 Maggiore Repeater a number of years ago and it had this
setup for xtal. temp. control on both the TX and RX xtals. Not sure the
manufacturer of the thermistors, but they look like what Bob is describing.

uhh-no trunking on those, conventional only.
The -1 (450-470) split will work fine down to about 430-435 with a
little tweak of the front

Yup, my error has been pointed out several times...
I was thinking of the TK-840.. as you will see further down in your
in-box...
But thanks for paying attention... it helps to keep bad info from
spreading.

Simple fix guys... change your license to reflect a PO Box as your
address...
Of course then you could still get mugged at your PO box...

Send your license to a PO box like I do.
It's legal and that way they can't find your
housealthough the tower and antennas may give
that away too

If you decide to use an 85 deg C oven, you must get the crystal cut for that
temperature.
I have plenty of GE ovens here if you need one6 or 12 volts.

Yes, I've noticed some short-term aging problems with crystals run at 50

I have found the Motorola 85 degree C gold oven to be quite
stable - the earlier black 65 degree C oven wasn't.
I think I found a brand new gold one in stock here a few weeks

Stability wasn't an issue in this case. I was using a temperature
controller with feedback; the sensor on the crystal was held within +/- 0.2
