QRP keyer software
Sorry but I can not send programmed devices to you (too little time, too much QRL). You will have to program the PIC yourself or find someone who can. The following file contains the firmware and (since 2011-07-03) the sourcecodes, which are now placed under the GNU General Purpose License:
The PIC16F84 is a quite old part, replaced with the 16F628. The latter has
more memory also for the CW message. The PIC16F628 is cheaper than the F84
now. In the meantime, even the PIC16F628 is outdated (and should be replaced
with the PIC16F628A). I only use the PIC16F628 (not the -A) though,
because I still have a few of those.
To 'burn' the firmware into the PIC, try any of the 'simple PIC programmers' (adaptors) out there. At least under Windows XP, the author's own PIC programmer (a software named "WinPIC") used to work well, and it supports the PIC16F84, PIC16F628, and PIC16F628A.
Since the PIC keyer firmware (machine code and sources) was put under the GPL (GNU General Public License) in 2011-07-03, you will find the sourcecode in the archive (*.zip, link above). You don't need the sources (*.asm) to run the PIC keyer, but you may want to understand how it works, or make your own improvements. You are invited to do so, but the GPL requires you to make the modified sources available to the public. Regardless of GPL or non-GPL (older versions), you are not allowed to use the keyer firmware for a commercial project trying to make "big money" from other's work. If you plan to make a kit from the PIC keyer, or sell programmed chips (for the price of the chip, plus a moderate fee to cover your efforts, shipping and handling) please get in touch with me.
Also, if you made modifications to the GPL'ed sourcecode, let me know the
web address of the modified sources so I can place a link to your site here.
Keyer firmware modifications
Vlad, RX3QFM, modified the 16F84 firmware for VHF "QRO" work, with modified PTT control. There is a 300 ms delay before playing the 1st recorded message, and a 9 second pause in "loop mode".
