Hi Thomas,
I’ve grown to love the prerecorded CW memories on my KX2. I’d fallen out of love with my 817ND because it didn’t have them.
Then I saw your video where you used a PicoKeyer. So… I ordered one.
But I messed up and it came in kit format.
So, tonight I built my first Kit-anything in about 30 years.
And, it actually worked!
What a cool little device..
Thank you for sharing this, Carl! This little kit is a lot of fun to build and quite affordable. The end product is one you’ll use for years to come as well.
It’s an amazingly capable little keyer and a proper value!
I too assembled an Ultra PicoKeyer. It gave keying errors when plugged into my KX2 or KX3. The Ring connector on the keyer’s output jack is connected and the trace to that pin must be cut for it to work with Elecraft radios. Once that was done it worked perfectly with my Elecraft radios and my FT-891.
I built one and found it very easy to do and am amazed how much he packed into that little chip’s firmware. There are tons of options and tricks if you work through the manual. The battery lasts forever too. Try turning on/off the automatic character and word spacing. It’s weird, but worth playing with -at least for practice. I built a paddle right into mine for one less wire when portable (I can still plug in a paddle). https://cdn-bio.qrz.com/l/ve3mal/20200405_121337.jpg
A little late to this blog post but I bought one last week and assembled mine after having a few beers. Quite possibly the easiest thing I’ve soldered up. Its a great way to add functionality to older Radios or ones where the keyer is more temperamental. I struggle with my Xiegu x6100 but this device solves that issue.
I also built one of those primarily to use with my FT-891. However when used with either an Elecraft KX2 or KX3, it causes a keying error. The ring connection on the keyer output is connected which the Elecraft radios don’t like. The solution to to cut the PCB trace on the keyer going to the ring connection on the keyer output. That has no adverse effect on keyer performance.
