[Elecraft] K3 Receive De-sense Problem

For the past few months, I have had intermittent receive de-sense with my K3/100-F, Serial 1523. Firmware 5.14, 2.13, 1.19 installed this week, but de-sense was there with previous firmware. Intermittently receive sensitivity will drop about ten dB. Usually happens after transmitting, but sometime

Anyway, just let us read both Rob Sherwood and Adam's test data and use them as a cross reference to each other. The issue is that Adam's data is flawed in at least two ways. The notch is wider than the SSB filter which means the noise is not being applied to the product detector or DSP ADC.

Re: [Elecraft] OT: CTCSS tones for repeaters

One additional note. When repeaters send CTCSS tones, many radios depend on the poor low frequency performance of small speakers to suppress the audio tone. This approach fails when using a car audio system to get enough volume to overcome wind noise etc. Having a fairly steep rolloff below 300
