Rockmite][ PicoKeyer chip ver. 44QPrice: $6.00
Dale Botkin, N0XAS, of Ham Gadgets sent me a new version of the custom PicoKeyer chip used in the Rockmite][ kits. I requested a slightly modified version of the message sending action. The timing for pressing the combination of the button and a paddle for sending a message was problematic for many. I suggested loosening the timing to help make selecting messages easier.
press & hold the push button
select either message memory by keying and holding the dit or dah lever
release the push button
Whichever lever is held on when the push button is release is the message that will be sent. Sounds like the old process? Well the NEW process is MUCH more forgiving about the push button timing. The OLD version code required the overall process to be fairly quick or else the chip would go into the command mode. The new chip won't go into the command mode unless the push button is held for about two seconds. This allows for a much more 'relaxed' operation for sending a message.
Another addition is that either message can now 'call' the other instead of chaining to the other. 'Calling' means that you can now send the entire called message within the first message. A simple example might be to have a CQ message in the dit memory and your call sign in the dah memory. If the dah memory was 'called' in the dit memory whenever you wanted it to send your call sign, your message memory would be used more efficiently.
