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

Roger, 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. David, W4SMT --- On Fri, 1/8/10, Don Wilhelm w3...@embarqmail.com wrote: Roger, I do not believe the transistors on the IO board should be very high on the

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

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. 73 matt W6NIA On Thu, 07 Jan 2010
