The other parts of this mod on page 3, affecting the KIO3 Audio I/O Module, must still be performed. 3. Installing this board can be done in lieu of pages 3-4 of the mod K3 Negative ALC and Ext Band Data Pull-up Mods. However, cutting the two traces on the RF board (under the bottom front cover) must still be performed as shown on page 2 of the mod instructions. I hope this clears up any confusion. Hopefully I got everything right (please correct me if I didn't Lyle). 73, Bill W4ZV -- View this message in context: http://n2.nabble.com/New-I-O-mod-kit-E850237-tp2312165p2436405.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

I went this route and updated (2) K3's with the E850235 boards. The boards are $20 verses the kit with some resistors spec. to 1% is $15. 73 de KE4WY Jim -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Bill W4ZV Sent: Friday, March 06, 2009 10:39 AM To: elecraft@mailman.qth.net Subject: [Elecraft] I/O mod kit REMIOUPGD (P/N E850235) W0MU Mike Fatchett wrote: For those wanting TTL outputs on the I/O board (Mike incorrectly stated E850237), you may now replace your old board with a new one. $15.00 ($20 is correct) plus shipping.

Re: [Elecraft] I/O mod kit REMIOUPGD (P/N E850235)
I have no clue what I received then. I will have to try to find the receipt. What board ships with new K3's? I think it is the one that has some of the mods and the pull up resistors for TTL levels. A slip of the foot you may soon recover, but a slip of the tongue you may never get over.
