Re: [Elecraft] K3 Upgrade Kit Question
Hi Roy, You are OK. Rev B -IS- the new KIO3 Digital Remote I/O board. (Same as supplied with the REMIOUPGD kit.) L1 is not jumpered. It is replaced with a zero ohm resistor on this board. 73, Eric WA6HHQ - Roy Morris wrote: > I have the Rev B E850235 K3 KIO3 Digital I/O PCB installed in my K3. Choke > L1 has NOT been jumpered.

Re: [Elecraft] K3 Upgrade Kit Question
Hi Joel: The upgrade to improve RF immunity affects two different I/O boards. The board with the audio connectors on it and the board with the DB9 and DB15 connectors. The ALC mod kit for $20 is a Rev B version of the board with the DB9 and DB15 connectors. And I don't know if the RF immunity mod was done to that board or not. Someone who has the Rev B board in front of them would have to comment on whether choke L1 has been jumpered across (or perhaps removed entirely). 73, Mike K2MK Joel R. Hallas Fri, 06 Mar 2009 13:58:46 -0800 I appreciate that the REMIOUPGD upgrade kit resolves ALC and band data pull-up issues -- neither of which are of interest to me at the moment. However, I wonder if the new board also includes updates to resolve the RF pickup problems in lines connected to the K3 rear-panel MIC, PHONES, PC IN/OUT and RS-232 rear-panel connectors? If so it would, IMHO, be worthwhile even if I never have anything that reads band data. Regards, Joel Joel R.

Re: [Elecraft] K3 Upgrade Kit Question
The REMIOUPGD board only deals with the -AGC and Band Data pull-up changes. We're basically offering it at or below cost for older K3s. (All newer ones have this.) For those interested in ordering this board, which replaces the digital I/O remote board on the KIO3, its available for $20 on our parts and mod kits order page: http://www.elecraft.com/order_form_parts.htm#K3%20Parts And our complete listing of K3 app notes and mods is: http://www.elecraft.com/K3/k3_app_notes.htm 73, Eric WA6HHQ Joel R.
