Hi Eric,
Thanks for the reply.
I am not sure that the cap from the ICOM is really a suitable replacement. It
is working for now at least. I am goung to try and find a proper replacement.
Seems that a typical 0-30 pf with a 5pf accross it is about right, maybe a
0-40pf would be better. Perhaps
Does really PVC absorb or RF or just act as a dielectric?
The reason I ask is I'm looking at encasing an antenna project for the sake
of weatherproofing and PVC would fit the bill rather easily.

Nuke a test piece and see if it gets hot.

I just happen to be today building a simple 12 meter 1/4 wave vertical using
this PVC I picked up at Lowes yesterday. I am using the pipe for a sleeve to
insulate the bottom 18 inches of the Aluminum tubing of the vertical from its
mounting pipe.
It says on the PVC pipe I purchased ..Rigid
One way might be to set the transmitter deviation to 5 kHz for a 2.5 kHz
deviation input signal. Set the VOX threshold to trip at about 3 kHz input
deviation and use it to switch in a 6 dBV pad to cut the deviation back down.
A fast attack VOX with a slow release would keep the audio from
There is a definite dielectric effect for slipping an antenna inside a PVC
pipe. Here are a couple of antennas that I build to insert inside PVC and both
have to be final tuned while inserted inside the support pipe.

A lot of people have voices, which are not considered Radio
or Broadcast Quality in both pitch and volume. Add a little
mic shyness and you're often stuck with lower average deviation.
I see that YAHOO added spaces to the links in my last post. Remove the spaces
to make the links work.

Instead of going through all of that trouble, why don't you find/buy a
150.8-174 MHz range PA? They work GREAT in the ham band even though they
are not spec'd for operation there. You can usually pick them up fairly
cheap since they were one of the most popular bandsplits.
I have several pulls
I have used schedule 40 PVC for several antennas from HF thru 440 MHz without a
problem. It does have a dielectric effect however that you must take into
account.
There is another plastic pipe called CPVC that does absorb RF at the higher
frequencies. You don't want to use that.
To make sure

is this a 100 watts + PA,HD version ?

This would be a 100W pull from a mobile. It's the same as used in a
station, but you would need to change the I/O connections to make it
work on a station heat sink.

I don't have enough space for all this stuff, so my cleaning continues. I am
