Re the AM quality question I can't detect any "clicking" or other distortion but then there are no high quality AM BC transmissions round here - they're messed up either with selective fading or because the transmission comes from more than one location on the same frequency.
The noise in between a string of dots is due to AGC PLS=nor. Setting AGC PLS = off cures it. 73 Graham ---------------------------------------------- From: "Wes Stewart" <[email protected]> [snip] Now it might be argued that these artifacts are at such a low level they would not be audible as distortion. Maybe, but they represent essentially a "static" situation. When listening to a string of dots sent with my '870 the difference between fast and slow AGC is clearly audible. When the signal is S4 or 5, with fast AGC there is garbage that essentially sounds like an increased noise level. A simple test such as tuning in WWV and listening to the voice ID and hearing the audio distortion and syllabic "clicking" disappear when simply turning the AGC off and turning the RG gain down appropriately indicates a real problem. If there are K3s out there that don't do this, then I want one of them.
