That would be almost at the bottom of any list of potential problems I
would suspect. The only gradual degradation mode I can think of for any
low power transistor, plastic encapsulated or otherwise, built in the
last 30 years by any reputable manufacturer occurs when the base-emitter
What specifically were the details of the supposed issue with older
K3's? Does the RS-232 line in the K3 reverse bias the emitter junction
(exceed BVebo) of that transistor?
No.
The KIO3 uses a twin-tee oscillator to generate to required negative
voltage. This is to eliminate the

I do not believe the transistors on the IO board should be very high on
the suspect list. It is rare to find a component failure unless it has
been subjected to some unusual stress - component degradation in 3 years
or less is highly unlikely, 20 to 40 years, maybe, but not 3.
May I
I agree with Don.. I wouldn't waste the time checking that transistor. It would
be an exercise in futility. My bet is on the KUSB.

Hi all,
I can't work out why my K3 has stopped communicating with my PC. Besides
the K3 utility I'm using HRD. Up to now I've used the KUSB which has
worked fine, it was bought with K3 #191 at the same time. I reinstalled
the drivers checked Baud rate (38400), swapped ports etc but still no
Roger,
I think you may be experiencing the problem I had which I asked about
yesterday

Check your ports with the elecraft utility, I had the same kind of
issue and I needed to find an open port that gave me 4800 bps.
I never had
If there's any doubt which COM port is used by the KUSB, you can use
the Device Manager - Ports to list all the COM ports. The one with
Prolific shown is your KUSB.
Sometimes in enumeration, USB-Serial adapters will change COM port ID
from boot to boot.

The K3 utility also lists the available ports.
