Will this new firmware work with the anticipated K144XV option module ?
By the way , what is the status of the option module ?

Yes, Jan, that is exactly what the new firmware is for. The K144XV has
been available for several months and many of us are now using it with
much success on 2 metres. See the order page on the Elecraft web site
for details of price and delivery.

Wayne, David, my question was unclear: I was referring to the optional PCB to
be installed inside the K144XV on top of the tranverter PCB.
The K144XV I already have. I am looking forward to the PLL function for
locking the 116 MHz VCXO to the 49.380MHz.
Is that project ongoing?

I got frustrated with my inability to get the vox setup correctly,
my problem getting the gain/antivox set correctly, NOT a k3 problem!
So I started keying my mic(s) with the XMIT button.
Mic's are a D-104 and a CM-500, neither one has it's own keying line.

If I push the REV button on the K3, the displayed center frequency

is not actually frozen, but it won't show VFO B until it is powered down
and then up.

I would assume so, since that's what I was running, too.
I did find a speaker workaround -- since the K3's audio is always hooked up
to the computer for digital modes through the Line Out port, I went into the
microphone dialog in Windows and turned on the listen to option. I now

Hi Smith,
This has been fixed in version 04.14 of K3 firmware, which is not yet
released. I can send you a copy by email if you wish.

Owen,
That bit of funny procedure for setting L8 and L9 first on 20 meters
(while the capacitors are set to the mid-point) is an interim step that
only needs to be done once (unless drastic changes are made to the
30/20m bandpass filter). It assures that the L8 and L9 are set to

You can find a LOT of information about the K3 (including its options)
by reading the section of the manual which explains each menu entry. I
highly recommend each user begin there immediately after after
familiarizing himself with the front and rear panel.

Lee,
Unless you are only trying to decode a few bands, I would find the
decode very difficult (if not impossible) without the use of inverters
to provide both a true and an inverted output for each of the band
outputs. It is much easier to use a 4 to 16 de-mux chip like the
74HC154. One
Ken,
The Band0-Band3 data is identical to Yaesu Band Data for
HF (160-6 meters). Any of the standard BCD to 1 of 10
or HEX to 1 of 16 decoders will work fine. If one were
using the K3 to drive a stack of transceivers and wanted
to be particularly clever, it is possible to use two
decoders if
Hello all,
I have a nice K1, it works very well on 7/10/14/21mhz. Lately I had idea to
buy a KFL1-2 module to add 2 more bands to my K1. However it seems,
according to manuals, that if I want to use, for instance 80 or 17 (bands
that I want to add), I should swamp both Filter Boards, is that true
Here's a great inexpensive band decoder:
http://www.unifiedmicro.com/decoder.html
The outputs are open collector. If you need a 12vdc source
instead, you will need to have a line driver or relay for each
output.
Older K3's will require the External Band Data Pullup part of the
K3 Negative ALC
As is, it doesn't decode 6M. Additional logic and hardware would be
required to decode the 1010 BCD output for 6M.

This might help: here's a PTT button you can build from parts at Radio Shack.
Use the PTT RCA jack instead of the 15-pin accessory connector; I just
forgot.

David,
You can only have one filter board in the K1 at a time.
My 4 band board is for 40m/30m/20m and 15m.
I have a 2 band board I swap in for 160m and 80m.
