Ok, I been all over the web and cant seem to find any documentation on the
critical cable lengths to build a 3 channel combiner. Does anyone happen to
have such a document.
Thanks,
Mike Mullarkey (K7PFJ)
Laryn - many tnx for the info. As I suspected., won't do ham 600 khz split.
I guess I'll dispose of.
Tnx again

There is more than one type of combiner possible... depending on
frequency spacing, band of operation and power level.

HI Skip,
Very tight outdoor cabinet. We need to combine TX 447.750, 447,850 and
464.900 into one antenna. I know this is not optimum but this is what we
have to work with.

I would have interest in this also as I need to combine 443.150 and
462.600 to 1 ant
thank you

Yup, won't do normal repeater split, but it is still useful to combine
two transmitters, two simplex stations, etc., as long as 3 mc.

I'm just addressing the two-port project above-- would not an ordinary
duplexer work just fine?

Yep, do it all the time.
When combining transmitters,
Does the Motorola Radius R100 repeater use a standard 2135 key for the
cabinet lock, or something else?

Yes - 2135. Unless its been fubard.

Technically, 15 kHz is normal/standard/original FM and 5 is NarrowBand
FM (which is what all hams use these days except for some links).

Yes 2135 is standard in the R100

The six R100S' that I have, use the 2135 key!

The majority have spoken! The 2135 key it is. Thanks to all who responded.
I am in the process of scanning a virgin R100 Service Manual into PDF, and I
wanted to include the key information- which the manual does not mention. I
don't have an R100 to verify which key it is.

We need to combine TX 447.750, 447,850 and 464.900 into one

have to work with.
The two Amateur Band Transmitters are 100KHz spaced with the
commercial box more than 10MHz higher.
To keep things short and sweet, the close spaced
The only way to do the close spaced frequencies 447.750 and 447.850 is with
a hybrid type combiner. The other channel 464.900 can be added in to the
antenna line with an isolator and a pass cavity or you could use a duplexer.
But with a duplexer you have to be careful of IM products more so than
17 matches
