Looks good... I actually found the manual to the external power
supply adapter I saw at a repeater site. Looks like the
I was recently given a HAL ID-1000 identifier. It's a 1RU cabinet device with
connections and test jacks on the back.
Seems to be diode-matrix programmed. Wouldn't mind setting it up for my call
and maybe using it for something down the road.
Does anyone have a manual or any idea how it is
The diagram for the adapter box also shows +13 Vdc is also routed
to one of the pins in the same plug (as well as ground) so I have
to figure out if that's a requirement or just an addition to the
adapter package. I did see where +13 Vdc was supplied to another
location on the repeater
How about a 7809 regulator IC with a 1N4004 diode in the ground leg to
raise the output voltage to 9.6V?
I was envisioning mounting it to something metal for heatsinking purposes,
but I guess you could probably use one of the screws on the backplane plus a
little TO220 heat sink. Whatever
Hey Skipp,
Have a look here... http://www.bcfmca.bc.ca/rptvhfmods.html

Hi all.
Built up a copy of the DC supply that was in a old Micor manual. Used the caps
and filter choke from an old
supply. Add a LM 317 with heat sink. Added MOV's and additional hf caps.
Seemed to work fine.
This fed a full micor repeater with all the normal modules. Worst case

There is nothing mysterious about 9.6 volts. It could be 9.00 volts
10.00 volts 11.00 12.00 volts or *anything* in between. The part that
is critical is that it is stiffly
In that case Just a straight 7809 or 7810 also would not require
isolating the tab and can be mounted straight to the metal chassis.
If it were me, I'd just use a 9 or 10 volt three terminal regulator
(7809 or 7810) and skip the whole LM-317 or diodes in the ground leg
deal. It only serves to

Or, how about putting old linear technology behind us, and embracing the
LM2576T-ADJ switching buck regulator? You can buy this puppy ready-made for
about $14:

Just change the 8200 ohm resistor to fix the output voltage. The
LM2576T-ADJ is rated at 3 amperes.

Picked up a UHF Micor repeater yesterday, Attached to it was a Lunar PAG463
preamp. Anybody have any recollection of these or info on them? Google has come
up dry.
Thanks!

Found this with google, Lunar product were made by Louis, KG6UH (back
when he was WB6NMT). You might try contacting him directly for a
schematic or manual. These are mostly from the 70s. You might try
googling just Luna Preamp like I did.

Thank you for all the replies and great information.
I have another question on code selection. Other than 411 being a code used for
open repeater, what is the criteria for picking a DPL code.
Also it looks like PL being preferred to DPL is not RFI specific as I have seen
on frequency
In the united states
Class C Class D CB were always on 26/27 MHz. Class A Class B CB was
462/467 MHz.
