[TenTec] V2.060b Release Comments

[Dick Green]

Smuck? Sheesh. It sounds like a click to me...

I tried several different headphones, including all three generations of
Bose noise-cancelling headphones and a set of David Clark aircraft
headphones retrofitted with 200-ohm Heil headphone elements.

I can confirm that the level of click varies with headphone impedance.
Overall, I found the click was least objectionable with the Heil elements. I
believe a Heil Pro Set will work well with this release.

Also, no click in the speaker here, either. Gives me some hope that Ten-Tec
can fix it, though the speaker and headphones use different audio chains
that may have different characteristics.

Bob, will you file a bug report?

BTW, it seems to me the audio control knob has a different taper at the low
end. Before, the gain would stay relatively high down to the bottom of the
scale, then suddenly cut off. In other words, volume could not be reduced
gradually to zero. Now there is a drop in volume at around half scale, then
no detectable change in volume level in the lower 20%-25% of the scale.
