Vern,
I am assuming you have RC-1000 and not RC-1000V (slight differences).
As to connecting to RC-1000 or to the MII I would recommend to
RC-1000. This gives you the option of switching between CTCSS or
carrier mode. It is probably easier...TS64 white wire (mute) to
P3-pin 7 for decode.

Typically a BP/BR has a wide pass and narrow notch. On mobile

improve this.

I recommend using International Crystal at 800-725-1426.
All you need to tell them is make of radio (Micor, GE Exec, etc),
frequency for TX and RX, method of payment (most all accept credit
cards) and address to send the crystal. They know all else needed;
IFs, tx multi, cut, etc.
Jim,
Wonder if this is with one of your radios or is consistant with others.
One note is the speed of the computer. RS232 at a particlar baud rate
is the same for all computers except for the data speed determind by
the time between bytes. Some have commented newer high speed computers

If you are looking for just a receiver Motorola made a nice Micor

these and built an AC supply inside.
The box will hold a VHF or UHF receiver. I've
I sell a repeater controller that can be put in a crossband mode. The

Don,
Actually the FCC stopped putting + on the Tech class a while back,
but kept in their data base who had passed the code so they could do
Novice and 10 meter HF work.
As others have said now with the deletion of the code requirement the
no-code-techs got the expanded previdledges of Novice
s.
The box is nice. One can do similar with seperation walls by using
multiple boxes.
I can't see paying $765 for this unit, but guess 222 MHz stuff hard
to find for some, hi.

I think the reason antenna manufactures use dbi over dbd is dbi is

One thing to keep in mind. The 150-160 version had 6 dbd gain, but due

Sounds as if you are looking for 2m/440 dual band antenna.

but cannot take falling ice. However, sounds as if some have had

With about all rigs manufactured in last 10 years or more CTCSS

Gary is correct. To really comment with good solutions one needs to

Remote base frequencies (suspect linking will be upside down from a

What antenna seperation can you work with.

Normally, and I say normally for Mot made a number of unified chassis

One methode is to use a hub repeater and have a transceiver at the
other repeaters linking to the hub. This hub can be one of the
repeaters in the system (one hub with the others having tranceivers
on this hub freq) or have a dedicated hub repeater on another band.
The least expensive

Not sure if your problem is with the rx or tx. 15k might be bit high

I agree with most of the replies. One can tell a serious repeater

The exec II is real easy to convert so might be easier to find one and

Looked at your controller. Looks pretty good. However, did not see

these is a simple thing. CW ID is mostly software. With small PIC

Since you have 500 kHz split you will need cans which as you have

If you have all these adapters in line feel lucky with only 1 db loss.
Good adapters are sometimes hard to find unless one wants to spend
