I have a 403~470 Desktrac repeater (two radios) with duplexer that I
could be convinced to part with, if this matches your needs.
Contact me off list if interested.

Hi All,
I am in need of a circuit to read amps to my controller.
Want to be able to read the current being used at the repeater site as well
as the charging current to the batteries.

Have an MSR-2000 working repeater, working in 150 mhz range that is complete

If you don't have a telco metering setup (line-man, transmission
line tester tims) the levels across the phone line can be
read with any decent AC volt meter.
Just be careful, some DMM's, even good ones, don't have accurate AC voltage
measurement above a few hundred Hertz. I have a

Hi Nigel,
Try East Coast Parts, same FET is used in Kenwoods. They show it as
obtainable, see below.

I have the proper test equipment. You need two to do the test right,
one for each end.

Hi Martin,
This is a 13.8v system, run off batteries and solar cells, the reason to be
able to monitor current, charging the batteries and current drain from the
repeater system.
I can monitor volts ok, just those damm amps running around.

Hey guys .You think your FCC is entertaining try the suggested band plan to
replace our uhf CB in Australia .All 40 channels are currently 25khz from
476.425 ch1 to 476.400 ch 40 .below is the new suggested plan in possibly
the next 5 years.
CB is going to 60 channels see ACMA:
Even for a on site solution, I'd love to get some suggestions as to how
the rest of the RB community measures current draw on their repeater systems
for the sake of battery backup time/size calculations, proper powering,
etc

The classic textbook method would be to put a current shunt in series with
your DC source and measure the voltage drop across it. A current shunt is
just a precision low-value resistor capable of handling the thru-current,
nothing fancy about it.
But, at low voltages (like 12V) and low

Perhaps it's possible to detect the voltage drop on the existing [+] line from
the battery bank, without the need for an additional shunt.
Some precision, high-current power supplies use a separate pair of sense
leads between the load and the voltage regulator, so the rated voltage appears

I'm looking for some Thermax RG-393 Mil-Spec Teflon 50 Ohm double shielded coax.
Was hoping to find someone that might have some left over pieces or pulls from

It needs to be a minimum of 16 but would like to find

Hi all!
I have a Celwave 633-6A-2N duplexer with a bandwidth of 450-470. Has anyone
had any luck/success taking this down to 441tx/446rx? This is a 6 cavity,
band reject 50w mobile duplexer.
Thanks Again!

It's been a while since I've tuned one to remember how low they will go, but
yes they will go to 441/446 without any problem unless there is something wrong
with it.

I have seen messages from others stating that those will only move a couple
of MHz from their factory-set frequencies... Moving the one that I had from
464/469 to 462/467 took the tuning screws almost to the limit of their
adjustment.

Good evening,
A couple of weeks ago someone listed several DB Products BSWR on the amateur
band.
Anybody remember what the VSWR is for DB 404 and DB 408?

I've never had much luck getting the little mobile duplexers that far out of
band. I was able to get enough isolation for a 2-watt repeater, but loss was
pretty bad. A friend who ordered a new one for the ham band had far better
results. The only real difference appeared to be lengths of the
