Because the meter and its cable's electrical length will change the tuning. You can read it at the antenna port of the duplexer if youre using one. This has already been covered in previous posts. 73,Lee I must be dense . From what I understand you have the transmitter (no tuning

Couldn't agree with you more. The important point is that you can't insert an SWR meter or wattmeter in the line to make adjustments and then take it out. The GE Z-match gives you the directional coupler which gives you a Why can't you take the swr meter out ? The Z-matcher is after the

The zmatcher matches the reactive impedance to the transmitter, not the resistive load - any cable changes or anything will affect this reactance. Ralph Mowery wrote: Couldn't agree with you more. The important point is that you can't insert an SWR meter or wattmeter in the line to make

I would certainly be interested to know where you obtained the digital meters - that looks really nice. I wonder if they are illuminated? Dave / NØATH - Original Message - From: Tony King - W4ZT [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Monday, January 26, 2004 8:58 PM
