2 meters is a little different since most G.E./Motorola radios have a
little better sensitivity, the noise floor of 2 meters is
much higher. I
once measured the 2 meter noise floor here to be ~3000 K, or
-122 dBm in a
16 kHz bandwidth. That's wny I almost never recommend a

Hi all,
I'm looking for a VHF duplexer for a portable repeater.
I see some mobile duplexers on ebay. I assume they're notch only.
How well would these work on 2M at a 600Khz split?
They won't. However, if they have 6 sections (6 adjustment screws), they

I have 3 UHF repeaters (TKR850) at one site, and one is getting some
inteference. The system has a single, top mounted (60') DB420
feeding a RX multicoupler (Sinclair with a window filter). From
there it goes to each repeater receiver. On the TX side, each
repeater has it's own
That is poor engineering practice. On any site with multiple transmitters
you must use a Circulator and Low pass filter to prevent mixing in the
amplifier stages. What you have happening is that the possible IM products
that fall within the passband of the amplifier stages are being amplified
I just put a backplane in the dishwasher ... it was dirty ... so?

The RXB MICOR is a Digital Voice Protection model, of which I have
several. It uses a TLN5979A backplane instead of the more common
TLN5644A. You MUST use the TLN5970A Station Control Module with the DVP
backplane, as it has many critical connections that are different from

---John, have a look here.
Our port-a-repeater for two meters uses a full size set of 4 can Wacom
duplexes in a nice box. I do not think any one makes a 600kz mobile or even
compact unit for two meters.

Eric,
I have confirmed I have the TLN5979A
backplane, and do indeed have the TLN5970A SCM. Can you email me what I need to
do to config this unit to use an external controller? I have the TX and RX
working fine seperately, just need to interface the controller.
Thanks!

Hi Everyone
New to group, appears to be one of the most prolific groups I have
come across.
I need some help, just acquired a VXR-5000 without programming lead /
interface. Does anyone have the circuit / connections software so I
can get it programmed for my local repeater frequencies etc.

I'd like to install a community tone panel on our group repeater.
I am considering the COM SPEC TP-3200 or the CONNECT SYSTEMS TP-154.
Can any one reccommend which unit to use ?

I would shoot for the 3200. It properly encodes and decodes reverse

Ok so now that I
have someunderstanding my belt for getting a repeater, what do I need wto
do for getting either a commercial frequency or ham radio allocation for the

Thanks
