I think the winner of the best response is Mark with the "Rube Goldberg"
statement followed by Kris with "wonky" and Lee with the plain old "WHY?"
Thank you all for your input. I appreciate the comments and the technical
advice.
My main motivation for doing this is A)to be different and weird..
The Titans were all CB rigs. I suggest doing a Google search for the info.

I checked and this is a CB radio with a 20mhz master systhesizer oscillator.
It might be capable of being moved to 10 meter ham band and it is an all mode
radio.

The Tram Titan original and Titan 2 were both high ene CB radios. The 3 may
also be a CB radio.

Hello Leroy,
How did you program the radios? In other words, using the software how
did you set up the Radiowide and Mode options in each radio.
Specifically the Options settings.

someone answered this but mainly for PA protection as most

I have a tram titan 3 radio that I am looking for information on. I have the
manual and the radio does power on. from the manual it lists freqs. in 20 MHz.
I'm looking to sell it so any information about the radio is appreciated!
OK, since we've activated the Wy Back Machine again, does anyone remember
the VHF high band West Coast Electronics remote mount mobiles?
I'm still looking for photos of the radio, especially an interior picture and
control head.
These were built in Los Angeles, used an 832A in the final and

Build it yourself. Use an LM7808 and and series two 1N4001's to lift the ground
lead up by 1.4 volts. I know 7809's are around but the 7808 is much more common
and cheaper.

One caution (from the "Introductory Information about the

Hi
yes they do work, not intended for use as a repeater, even with
a fan running full pwr is risky, depends on what sort of rptr if
amateur then some of the overs can and do last 10 minutes or
more. Again if amateur with a 600Kc split the dupexer will cost
you a load of money

In response to your Gm300s as repeaters, I have
been using them for years without any problems,
power up full(with fan coming on at transmit) and
a 600
KHz spacing. I also have a pair of SM 50s working
as a repeater with a much wider spacing. It has
been operating for years now, without any
problem
One caution -
The 900MHz Motorola GTX series radios have a firmware
bug in them and will NOT do tone reverse burst at all.
The DCS side of the radio is just fine.
This is documented on the GTX pages at repeater-builder.
Since every 900MHz user radio that is in use started out as
a commercial 2-wa
Hi
they work OK but you must turn the tx pwr right down and
fit a fan or pa won't last long. It is down to the duplexer finding
a unit suitable at the right price will be almost impossible, the 5Mhz split
is ok as you can get cheap duplexers from Hong Kong

Steve,
So the reason for turning down the power is for PA protection or RF
suppression?

I'm wondering about the suitability of a pair of VHF GM300s as a repeater. Is
the shielding sufficient to allow 600 kHz between Rx and Tx? If not, what is
the suggested minimum?
Same questions for UHF SM50, but with a 5 mHz split?

I tried posting this to a year-old thread, but I'm afraid it wont be seen! I'm
having difficulties in that when I plug my repeater cable between my two SM50s,
the transmit radio immediately goes into transmit. I am fairly certain I have
everything programmed properly, with Pin 8 programmed for

Less than 1 Amp is the good news...
Now instead of building a 3 terminal LM-317 regulator circuit
do we want to instead buy a pre-made complete regulator board
off Ebay for about $7 and shipping?

One could point out that placing a small inductance to ground in series with
the ungrounded radiator and feeding the junction of the two is quite similar
to tapping up the grounded radiating element to attain a match.
