New bug, popping on dah side
Locked
 
|
I hooked up a new bug (begali intrepid) and am noticing popping when keying
dahs - I if I add a 4.7uF bypass across the key line it clears this up but it’ll sometimes make it so there’s no dits. I can’t figure this one out - is there something I need to do to make sure there’s no extra garbage when I’m keying? (Contacts are clean) Thanks. -- TJ Campie Sent with Airmail ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

TJ,
No callsign? What rig are you using? Are you hearing the popping sound in the sidetone? Definitely don't put a cap across the contacts. You may need to diddle with your QSK settings. Other users may be able to help you more if they know which rig. _____________ 73, Jim - N4ST -----Original Message----- From: [hidden email] <[hidden email]> On Behalf Of TJ Campie Sent: Sunday, April 28, 2019 13:03 To: Elecraft <[hidden email]> Subject: [Elecraft] New bug, popping on dah side I hooked up a new bug (begali intrepid) and am noticing popping when keying dahs - I if I add a 4.7uF bypass across the key line it clears this up but it’ll sometimes make it so there’s no dits.

Nice!! A Begali Intrepid,
All bugs will have contact bounce. K3 does not handle them well at all, same for KX3/2. K2 is much more tolerant. Though normally for the dot side. I fixed it with a home-brew debouncer: https://www.kn5l.net/debounce555/ Others cam be found on the WWW. It was fun designing and building one.

TJ, your six miles line of sight, what to come by and borrow it for a
while to see if it's a fix? John KN5L On 4/28/19 12:11 PM, John Oppenheimer wrote: > Nice!! A Begali Intrepid, > > All bugs will have contact bounce.

I have tried all kinds of debouncing circuits, but the one that has
always worked best is simply a 12v reed relay with a 10uf capacitor across its coil -- not across the contacts! I used an SPST reed relay I got at the now-defunct Radio Shack, but there are many such relays that are suitable. Reed relays are fast enough to follow the contact bounce of the bug, hence the 10uf across the coil. This works fine with a 9v battery or from your usual 12v station PS. 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco/ On 28/04/2019 20:11, John Oppenheimer wrote: > Nice!!

I have an Elecraft K3S with last software release.
I use it with my Begali Intrepid and my Vibroplex Presentation mod. 1964. Always, I make at least 5 qsos/day, at speed 15-22wpm Same firmware release ago, I had problems with the Vibroplex Presentation, I dont remember exactly the message on the K3s screen but it give an error when manipulating the bug. After setting better the Vibroplex Presentation, with better dots contact regulation, as suggested by GM4GZQ "Adjusting your bug" article, the problem has been solved. Only with one of the last release of firmware the problem returned, but now, with last 5.67 version, I have no problem with Vibroplex or Intrepid. The Intrepid anyway have a lot less bounces on dots contact than the Vibroplex. The K3S doesnt like very much contact bounces, anyway if you reduce them there are not problems at all.
