I think you'll find standard, nominal Line-In/Out consumer levels to be
referenced to -10 dBV irrespective of Z, where 0dBV = 1 Vrms. This standard
started with the old IHF, merged into EIA, and then somewhere along the way

Yes. 600 ohms has not been part
In the past, it was suggested that folks add a T or Pi attenuator to
bring the level down. I build two 13 dB T attenuators for 600 ohms,
and this worked fine - one for MIC IN and the other for SPKR OUT -

Hi-
I have two K3/100 rigs. One is enough...sort of.
For sale is a factory built K3/100 in perfect condition. Not a scratch, non
smoking environment. I will ship it and insure it in the lower 48. Not outside
of U.S.
This rig includes:
Power amplifier...KPA3-F
Internal antenna
I've not seen that myself, Gerry. Since you know it's not shorted, suggest
you:
1) Check power at the holder terminals and not just across the battery? If

in between the battery and the contact, effectively
Ok I've been very busy enjoying my K3 for almost one year now !!
( serial No 133) It's an amazing radio.
I've just started to pay creedence to the need to update/modify/ get

600ohms still seems to be the practice for ship and aircraft intercoms that
I've come across recently.

Yes. 600 ohms has not been part of audio practice, pro or consumer, for at
least 40 years. ALL line level and mic level audio circuits, pro and
consumer, are low impedance
I don't really use my speaker very often, but I just wanted to keep my K3s
up to date by installing the AF amp and LINE OUT AF mods. They went in very
easily even though I chose the harder installation choices. I even piggy

My K3 (1428) has had a problem maintaining date and time information when
the power is off. Since I didn't buy my K3 to be a $3000 clock/calendar, this

turn it back on the date normally goes to 12.19.01 (US Format)

One unique feature of the K3 is that the S meter operates even when AGC is
turned off. Lately I've taken to operating often with AGC off to maximize
weak signal performance (using the RF gain to control volume), but have
noted that the S meter reading is a strong function of whether AGC is on or

Pull up the schematics on the internet and study how the jacks are wired.

For those now or in the future wanting to setup the PK-232 with the K3
using FSK here is the information. I would think you could do this very
similarly for the Hal and other TNC'S. Of course the specific wiring
would be different but the same general hook up should work. This set

I would highly recommend that you use a bare 15 pin connector rather
than a video cable. There are only 2 wires required, FSK IN and Ground.
The video cables (cut off defunct monitors) that I have encountered have
several pins connected together which will tie together those pins on

did not check each and everyone. I will do that. Anyway your point is
