Sorry, my oversite. It is vhf and I don't have a wattmeter capable of 1 watt or less. I need to invest in the proper slug for my wattmeter, no doubt.
With the xmit channel element always running, I see a continous measurable output from the exciter or the test set. No difference whether the repeater is in xmit mode or idle. Just curious as to what I should be seeing. I have a spare exciter board and aligned both as per manual, both give the exact reading which is down from what the manual gives as typical..Thanks...Don --- In [email protected], "George Sintchak" <[EMAIL PROTECTED]> wrote: > > Don, You don't mention what band/frequency the Micor is on, (I assume > UHF) and if you have a station monitor as you stated, it has a > wattmeter built in that can measure the power level from the low > level exciter board up through the output stage.
