two more cents - are we rich, yet?
Couple more comments on K3 audio quality and etc.
The MOT metal mobile speakers were designed for FM mobile and did
sound good. I don't have any so have not tried marrying one to a
K3. SSB sounds different than FM, especially full quieted FM.
Installed a lot of Micors, Mitrek, Syntors, etc.
I did note the difference in sound when I went from the old FT-847 to
the K3. Did take a little time to adjust to "its" sound.
I have made a couple adjustments in the AGC attack with subtle
changes in the sound. But boy did it hear better on HF!
The full spectrum response of the SONY MDR-V600 stereo headset is nicest.
I often run bw down to as low as 2.1 KHz on SSB (2.8-KHz filter) and
that reduces white noise level. SNR is directly proportional to
bw. So that improves the SNR. Of course in a crowded band it also
reduces QRM. HF QRM is not so bad here as it must be in civilized
areas. Year's ago I ran off the grid on batteries and had S0 noise
floor on 75m phone using a TS-180S and dipole. I could really hear
the weak one's. Now its more likely S5 noise floor (different radio
- different s-meter - on the grid!).
Not sure upgrading my K3 audio board would make enough difference for
me. Any guess on cost and difficulty of installation? I have yet to
install my new synth boards - too busy building 2m amplifiers. It
will be interesting to see what difference that will make.
I think audio quality is too personal to provide universal
solution. In the old day's choosing a stereo or speakers, I would go
to an up-scale shop in Hollywood or Beverly Hills to chose the
equipment as they had lavish sound rooms - then head back to West LA
discount stores to buy one. I found JBL were the best to my ears.
