New I/O mod kit E850237
Locked
 
|
For those wanting TTL outputs on the I/O board, you may now replace your old
board with a new one. $15.00 plus shipping. This is an alternative to soldering the 2.2k resistors on the old board.

Sorry K3.
All I was told that this board had the pull up resistor installed. W0MU "A slip of the foot you may soon recover, but a slip of the tongue you may never get over."

I would assume that when installing this board that its best that we cut
the two traces on the main board so that the negative ALC mod isn't half way done right? I've got the board in hand now just need to find the time to tear the shack apart again and start up on mods again. I've done them all but this one... At some point in time the pulled up band data will prove useful so I do need to get it done... The ALC mod is just so I can say my K3 is up to snuff and the same as the newer ones. ~Brett On Wed, 2009-02-11 at 17:31 -0700, W0MU Mike Fatchett wrote: > Sorry K3. > > All I was told that this board had the pull up resistor installed. > > W0MU > > "A slip of the foot you may soon recover, but a slip of the tongue you may > never get over."

In reply to this post by w0mu
For the record, I'm posting this response from Lyle KK7P to me (his comments preceded by ###): Which of the following mods involving the KIO3 does this affect? http://www.elecraft.com/K3/k3_app_notes.htm ###I'm not sure I understand the question, but I'll try and answer anyway. ###I assume by E850237 you mean the KIO3 Remote (aka Digital) IO board that is included in the REMIOUPGD mod kit. I believe the correct part number for this is E850235. **K3 AF OutPut Mod Kit* <http://www.elecraft.com/K3/mods/AF_Output_Mod_Rev_C.pdf> ###No impact, not part of the digital IO board. **Improving the Immunity of the Rear-Panel RS232 and Audio Connectors to RF <http://www.elecraft.com/K3/mods/ELECRAFT_Application_Note_Improving_the_Immunity_of_the_Rear-Panel_KIO3_RS232_and_Audio_Connectors_to_RF.pdf> ###Ground return inductor mod on the RS232 port only. ###The RFI mods list some optional inductor bypasses. The optional ones are not done on the new board; they are still optional based on your shack, environment and station system design. **K3 AF Mod kit <http://www.elecraft.com/K3/mods/K3_AF_Stage_Upgrade_Instructions_Rev_B.pdf> ###No impact, not part of the digital IO board. **K3 Negative ALC and Ext Band Data Pull-up Mods <http://www.elecraft.com/K3/mods/K3ALCMod_Rev_B.pdf> ###Does the digital IO board portion. The RF board cuts portion *must* still be done. To summarize: 1. The board involved is the KIO3 Remote IO (aka "Digital") Board, P/N E850235 and is available for $20 plus shipping as REMIOUPGD on this page: http://www.elecraft.com/order_form_parts.htm#K3%20Parts 2. Installing this board can be done in lieu of grounding the RS232 Ground Choke on the Remote I/O Module as shown in Figure 5 of the mod "Improving the Immunity of the Rear-Panel RS232 and Audio Connectors to RF". 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 |

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: [hidden email] [mailto:[hidden email]] On Behalf Of Bill W4ZV Sent: Friday, March 06, 2009 10:39 AM To: [hidden email] 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.

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.
