Pse some K3 adjustment advice to this appliance operator:
1. My K3-100 factory blt # 309 has vy loud brief noise bursts... specifically the effect if a vfo were transmitting and vy rapidly swished past my rcve freq. The resulting blast of tone is much louder than the voice I am listening to and hurts my ears with headphones on. What to do?
2. S-3 to 7 BCI on 160-80-40 and 20 with 2.0 filter setting (wider is worse)... I hear AM voice syllibants (puff sounds) and plosives and occasionally distorted music. This mostly across the bands and definitely is not a single harmonic, altho those come and go from time to time, also. I have the ICE BCI filter in ant. line just behind rig. Using 4 different antennas. OK station gnd. What to do?
Gripes:
-Info line on the B VFO space disappears too fast for me after pushing a button and getting info in that line.
-Auto notch on hetrodyne not effective with BW wider than 2.6... no notching.
-Do not know how to adjust the manual notch.
-rig needs a balance control (is it there???) to compensate for one ear being less sensitive than the other (got old fast).
-Heard a 10 over 9 signal ELEVEN kc below its fundamental.... splatter or deficient selectivity??? BW 1.9 and 1.60 settings.
-Auto SPOT seems not to work every time (may be operator error)... Same is true with CW or RTTY decoding read-out.
Brags:
-VOX on ssb is really super, best I have ever used and best I can imagine.
-AGC is vy nice except for pops in #1 above.
-CW speed and RF power read-out on the dial... nice.
-Delta f amber light is nice reminder.
-The ATU is lightning fast.... amazing.
-Main knob feel is a delight and tuning rates (selectable) are perfect. Too, nice to hv the rapid QSY also on the RIT knob!-AF selectable volume boost is needed and is good.
-Rig is physically beautiful and control layout is super... any smaller and trouble, tho.
-Really tacky feet keep light weight rig on the table ok.
-Band width graphic on the big dial.... and many others being there is great. Dial color is vy nice and vy adjustable.
Needs:
-Video output of main dial info and a panadapter (bandscope).... big and urgent need for me.
-Direct keybrd input to send CW and RTTY (is it there now?) to go with the nice CW/RTTY reader.
-Individual band select buttons for direct one-push entry.
-Book needs a list of the front and rear controls by name, number on the illustrations and brief function description (separate from the narrative version that is in the book now).
-Book needs a good index. Contents page is not enuf.
