Tom, Thanks for that tip. I so rarely go into the menu so was not even aware of a mic gain "switch". I wonder what the level change is? If it is 3-dB or more it might affect FM deviation sufficiently to "fix" the low deviation reports I get. If that will accomplish the deviation issue perhaps firmware can be added some day for FM mode which will set the mic gain? I use my K3 on 6m/2m/222/432/1296 so FM is more than a "funny curiosity on 10m" for me.
I'll have to experiment on one of the 2m FM channels and get some on-air reports. I only have one radio at the present (the K3) so I cannot monitor my signal on another radio to determine the affect. I do long for the days when I had a service monitor at work and could make such tests so simply. I am in negotiation to buy a used HP-141T spectrum analyzer which would display FM deviation of a tone visually. I was just "playing" with the NR adjustments this morning and noting their effect - interesting. What's so nice about the K3: you own it two years and still have stuff to discover about it! 73, Ed - KL7UW --------------------------- Date: Sun, 29 Apr 2012 08:23:58 +0100 From: "Tom Boucher" <t...@telemetry.demon.co.uk> Subject: [Elecraft] [K3] FM Transmit Audio Level To: "elec...@mailman.qth.net" <elecraft@mailman.qth.net> Message-ID: <85431716172341E398D75267D9C13EC5@Tom> Content-Type: text/plain; charset="iso-8859-1" Ed, Don't forget there is a High/Low mike gain setting (MAIN:MIC SEL Tap 1 to toggle High/Low). Probably not much use to you unless it can be somehow selected for FM only. 73 Tom G3OLB KL7UW wrote: <So I wonder if there is an internal mic gain pot that can be adjusted for FM?> 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-QRT, 1296-?, 3400-?
