Well, an L45W is nice and easy. It's one of the old-style connectors that

Oh, forgot a minor detail. In step 7 where you flare the shield out,
compact the dielectric around the outer perimeter so that it doesn't get

Do any of you LMR folks have schematics and/or module pinouts for the M4010

Have you started with the basics and checked the power supply for proper
voltage, regulation under load, and AC ripple?

Steve, just changing crystals should not create this problem, and should not
require modifications. If the spurs are making it out with significant
amplitude, they're probably being generated in a later stage.
If the frequency was just changed, how was the transmitter and power amp tuned?

Hi Eric,
I very much appreciate any insight on this subject. I have obtained far
more useful information than I could imagine before seeking help here.
The friend who did the tuning did so several years ago right before moving
his QTH and donating the duplexer to our club. He can't remember

Some TKR-820 repeaters will not tune into the ham band.
I sent one in to be tuned in the ham band, it's still here in the box, to
Kenwood East for a complete alignment and tuning.
Kenwood East could NOT get the unit to tune into the ham band and remain stable.
They did test the unit further and

A recent post concerning intermod created by rusty bolts, washers, etc. caught

Thru the years I have used all kinds of methods to tune duplexers. The
first was a diode detector that fed a voltage to an O'scope. The signal
generator was an HT. Next was an IFR-1500 and pads on the input/output
of the cans. My present mode of tuning is with a network analyzer.
