Known as lying to the k3 to get 8kc bandwidth for AM you need the fm filter. 
Just lie and tell it it is the AM filter.

Thanks, guys. I was about to ask whether the FM filter would also work for AM transmit, but it appears from other answers here that it does. (The manual says you need an AM filter for AM transmit, but it could be wrong about that.)

6 kHz filter for K3

James F. Boehner, MD
 

If I had to do it again, I would have chosen the 13 kHz filter over the 6 kHz filter.

13k FM filter here as well, for AM and FM.

Filters (in general)

kg9hfrank@gmail.com
 

There has been quite of discussion here as well as other boards as of late on filters.   I upgraded my K3 main and sub along the way.  I am curious how many folks here have taken a tracker and seen their filter on an analyzer?   I have not done this (yet) but curious what anyone here has seen. As we age, our filters also are aging.  Any comments related to offset, gain, replacement of older ones, especially the very narrow ones.  Thoughts?  de KG9H

Hi Steve,

May I suggest that you buy a 13kHz  FM filter as that will give you both modes with one purchase and having used both bandwidths I wouldn't consider a 6kHz filter.

Dave, thanks. Inrad doesn't have any 6 kHz or wider filters at the moment.

I would up buying an FM filter on eBay from N7YV. That should also give me  FM capability if I ever want it. I'll let everyone know how it works out.

Steve,

Quite a few filters are still available for the K3 from Innrad:

I bought all of mine from them.

Hello 
Can explain how I can transfer a recording I made of a part of a QSO using my K3 and transfer it to an audio file that I can email. I have a MacBook Pro which has Piezo software installed if that is any help. Keith Trinity if you see this feel free to email me directly.

VFO B Display decode only?

trevor MØTDZ / MØDX
 

When decoding CW my VFO B display keeps reverting to the VFO B frequency in between decoding.  It then takes a shile to swap back to decoding missing parts of the message being sent.  Is there a setting that will stop it doing that as I would rather have the constant decoded morse as I know what I have the VFO set to and am not changing it?

6M TX Gain LP Calibration is high on K3S

Chuck ke9uw
 

When I got this K3S new a few years ago, the LP 6M TX gain cal did not calibrate and eventually it calibrated at "52000 kHz TXGain LP 121". I didn't want to send it back, and that's why I kept calibrating it until I got the odd reading but at least it completed the cal. I don't get on 6M much.
Now I'm wondering why it is high. The HP 6M TX gain cal is "52000 kHz TXGain HP  17" which seems ok.
Anything to be concerned about?

Can anyone tell me the SMD part # for the UI on the KI03 and where to order it? The one on my board shows sn75c1406 g4 which doesn't show up on any datasheet, I've found others that are close except for different letters on the end.
Well have you tried ordering from Elecraft?
I see several problems here. I belive your UI designation should be U1. Second the last letters are usually about the case style and case material. Cases types could be SMD and DIP. Of course you want the SMD but there could be two case materials: Ceramic and Plastic.  The ceramic and plastic should be interchangeable but of course SMD and DIP are not. 
To know for sure go to the TI website and download a SN75C1406 data sheet.
