Re: Sluggish Encoders

[Elecraft mailing list]

My K3 also has been having trouble with sluggish encoders. The worst one is keyer speed. Sometimes (not always) turning the speed control doesn't change the speed. The power control takes FOREVER to move from 100 watts down to 50 or less. My shift control is jumpy at times but width seems to be OK.

Since the speed and shift controls are not always problematic, I suspect a software conflict.

I had the same problem with my CMP / PWR encoder for several years. I
finally replaced all four of the push button encoders last November. I
wrote up what I did at <http://www.n5na.net/s9y/>.

That is what support just told me too.

Sounds like a bad batch of encoders to me.

I may change them out when I get my new synthesizers.

Under typical operating conditions I sometimes notice a delayed response of the WIDTH encoder. With the antenna disconnected, the same encoder's response is immediate. Could it be that in addition to defective encoder components, CPU load is another cause?
