Please provide make and model of repeater, controller, duplexer and
input frequency.
On that note I should point out that most explosives devices don't
like being exposed to RF.
And AM NTSC video tends to get into a bunch of stuff with the sync pulses.
I think this warning appears in most mobile radio manuals and is
posted around blasting sites.

Wrong channel stepping on the radio it is connected to?

Take that crap up to 2.4 GHz with the rest of the garbage.
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.

How about a 7809 regulator IC with a 1N4004 diode in the ground leg to
raise the output voltage to 9.6V?

How about 1.25 MHz RF coming down the outer jacket of the UHF antenna
and into the ground of the system? You have about 200 ft or so of
coax? Try a mag mount antenna temporarily.
Not really sure how you'd cure that though. Not sure if snap on RF
beads would work on coax with a signal going in the

I'd be intrested in one or both of the duplexers, would you take $50
and $20 shipping each?

If you have a spectrum analyzer, look at the receiver pass side of the
duplexer, you should see the garbage come up as soon as the
transmitter keys. Also if you do not modulate the repeater the
garbage should be decode able with a radio such as the Kenwood TH-F6
or Yaesu VX-7 set to AM mode tuned
I was surprised how well the scan stitch worked, it even has fine skew controls.
I'm more interested in an OCR program that will spit out regenerated
text with the correct font and in the right places for a PDF.
ARCsoft Scan and Stitch is what I used.

Yeah, I could see that. He did not specify the crystal manufacture, plus the
factory compensated the element to what crystal was originally in it.

Seriously, some people need to read the original message before replying.
The original complaint was running out of tunning range on the piston

I think you are referring to not being able to net the rocks to the
correct frequency in your channel element. This is usually due to not
enough or too much capacitance in the oscillator circuit. Good crystal
manufacturers will supply the mid range temperature compensation
capacitor with their crys
Do you know what type of coax is going up to the antenna?
Foil/Braid coax such as LMR-400 and 9913 are known desense generators.
