I know is a little off the path but I really need some help
with a Cushman CE-50. When the green signal light on the right hand side would
not work, I found the two wires, a light green and a white with green stripe, had
been cut and left hanging. Also a yellow wire from the deviation
Hi Gary,
It's not exclusively related to the Loaded and Unloaded
Q of the Cavity.
Cavities do get warm under extreme conditions, but
I've yet to feel a typical two-way radio cavity rise
more than warm to the touch in high power pager type
operation.
I have seen some small cavity mfgrs

Skipp,
I want to make sure I've got this straight in my

For the final tweak on the transmit side bandpass setting I
would:
A) Look for minimum reflected power from the duplexer
'xmt' port back to towards the transmitter.
B) And then I'd also look for maximum forward out of the
Inexpensive directinal couplers will not have high enough directivity
to give accurate readings. They will work, but the accuracy is
degraded over a high directivity coupler.

I just added some new info, courtesy of WA6BZS to my Vertex VXR-7000
repeater page. It is about using a different audio input pin on the
controller connector. Good stuff! I will also add info on getting a PL
decode indication from the RJ jack on back of the repeater. WA6BZS

P/N Z30-16-5-75 is $29.95
P/N ZADC-10-4-75 is $54.95
etc.
Those are 75 ohm units.
Take a look at the ZFDC-10-2. I picked one up at Dayton for a few
bucks.

Same with me, currently just try to find out why the
AF MONI sound is more loud than the retransmit AF out.
I tried to adjust VR4001 but it doesn't much help.
And your comment give me some ideas.
At schematic diagram and in service manual book, they
mentioned about -20db AF attenuate by R4180
Can anybody can advise me for tunning duplexer with
minimum tools?
For example case:
I have to change TX-RX frequensi in some place, where
I only have SWR and some HT and volt meter?
thanks

I was curious as to if the units are hardwired in or is it some card
that you can change.
Thanks

A case of beer, an SWR meter, and a radio. Tune for minimum SWR. The
Changing the PL deck is something that I personally haven't tried to do.
According to the literature, you need to order the R100 from Motorola with
the proper deck already installed.
From looking at Page 5 of the Service Manual, it appears there is more to it
than just swapping out the PL deck
there is a number of chips and caps. but it can be done. less work to go
from DPL to pl.
or is it is dpl add a tone panel.
