I shoulda picked one up at Dayton... I'm working on a 2M repeater and have replaced the multiplier exciter with a PLL exciter. I love these things-- very clean output and one tuning coil.
The PLL exciter I had on hand has no audio processor module, so I'm looking for a complete PLL exciter. Then I'll have spare parts on hand too. Reply to my call at arrl dot net. Thanks! Laryn K8TVZ
