Capacitive Keyer Requirements? #bitx40 #ubitx #cw

 

Folks,

?I'm continuing to stuff CW into my brain and hope to be able to operate at some point in the not too distant future.? Until then, I'm trying to wrap my mind around keyers.? I have a decent straight key yet don't know much about implementing paddles.? A search returned a distant post about capacitive capability in Allard's code for the BITX40.? Is there similar capability built into the ?BITX code?? Is is enough to wire, for example, a paddle made from a piece of double sided PCB to activate the keyer code?? Or is there more to using touch to activate the keyer?

Thanks and 73,
Andy, KG5RKP

There are circuits needed to convert touch into closed switch action. A search should turn up US and other sellers of this type of paddle kits.

I find a mechanical paddle more to my liking. Qrpguys and maybe n8dah has paddle kits that are inexpensive.

Have fun exploring.?

I have tried various touch paddles in the past and did not like them. One model (home brew), would stop working after awhile. I never found the cause of this issue. The second one I purchased and it had a metal plate to rest one's fist on....paddle worked fair but was tough to get used to as my fingers would tend to wander to the front of the sensing pad and would miss dits or dashes after awhile.
Art, W8CIT had an article in QST last year about a force touch paddle that sounded intriguing but I never built it up.
Being a mechanical type, I like paddles that have many adjustments available.
Good luck with your endeavors.

Thanks Curt!? I see what you mean about touch-specific 'keyer interfaces'.? I explored the capabilities of the BITX and ?BITX but neglected to consider a more 'universal' connection.? I had to apologize to my TS-530 so it didn't jump off the desk and land on my bare feet. hihi??

Hi Barry,

? ?Thanks for sharing your experience.? I'll start a search for something mechanical!??

Hello:

Notice your message as I was clearing out those unneeded messages. Noticed ?your below message on touch paddles.?

Many years ago I had the use of a stand alone iambic keyer with touch paddles. In the end, the owner needed the keyer back. The paddles were ?like the second one you mention below. ?

I injured my right CW hand ?in an auto accident. ?Was thinking that touch paddles might be a solution for sending CW with this hand. Wondering where did you obtain ?the second touch paddles from and how much did they cost? ??

Thank You in advance for any info.

The touch paddle was from QSKllc.com and was the TP-1. It cost about $179.
