[Elecraft] T1 ATU Not Staying In Tune Mode

2022-10-30 Thread Tony 

All:

Is it normal for the T1 ATU not to stay in tune mode after tuning an 
antenna? I've noticed that my T1 will occasionally default back to power 
mode so I need to switch the T1 back into tune mode whenever I switch 
bands and need to re-tune.

Is there a reliability issue with these amps?


Mine's been running with no issues since late June 2019. I use it 
extensively with legal limit CW, SSB, and RTTY contesting on HF and 
160M, as well as seriously chasing grids on 6M using WSJT modes, where I 
limit the power to about 1200W.


Initially, I was running the fans high on 6M to keep temp down on the 
devices, but on advice from Elecraft engineer K6XX, backed the default 
speed to minimum and let the firmware take care of protect the amp. Runs 
fine that way.

Remember, almost no one posts messages saying "My xxx hasn't failed." Only
the bad news shows up on the reflectors.

Re: [Elecraft] k pod repair

2022-10-30 Thread Josh Fiden 
Not a huge e-switch fan. If I was going to the trouble to replace it, I’d get 
the equivalent Alps part. It’s a common 12mm tact. Mouser stocks Alps.

Re: [Elecraft] KPA1500 RELIABILITY

2022-10-30 Thread john 
Is there a common component failure with this KPA1500 amp or does something
different break every time?  Is there a certain mode, power level or type of
antenna/feedline that causes failures?  I also monitor the SPE Expert list
and some people have multiple LDMOS failures while others have no issues
ever. N4ZR posted a similar question two months ago when someone else had
multiple LDMOS failures and I did not see any responses.

2022-10-30 Thread Mark Musick 
Hi George,
We need a little more information. 
How many times have you sent it back?
What were the issues? Was it the same issue each time you sent it back?
Give us some detailed information about the issue(s).
I have KPA1500 serial number 112. I took delivery in April 2017. It has never 
been back to CA.
I have used it on 6 meters FT8, MSK144, Q65 and CW a lot. I finished my 6 meter 
DXCC in July 2021. I've used it in many QSO parties. It hasn't missed a beat.
It has been a pleasant upgrade from the Alpha 9500 that it replaced.
I don't know how many KPA1500s are out there, but I'm sure it is a lot. I don't 
think there is a reliability issue with these amps.
If you have been watching this reflector, yes there have been amps with 
failures. And yes, some have failed due to a bad component. However, the vast 
majority of the returns are because the operator was subjecting the amp to 
something it didn't like.
