K1 - 2 band, is possible to add another 2 band PCB ?

[roney]

Hello, now that my Rig is ready, I want to ask something that wasn't clear
when I bought it.

In Elecraft website, there is a "*KFL1-2
<http://www.elecraft.com/k1_page.htm#K1%20Options> Additional 2 Band Module*";
I did not buy it, because I still don't know if it works.

I already have B1 as 3.500 mhz
I already have B2 as 21.000 mhz

If I buy and add the second 2 band module, can I have all together 4 bands
in my Rig ?
(Like adding B3 as 14.000 mhz, and B4 as 7.000 mhz)

Thanks
Roney PY1ZB

All 4 bands cannot be installed at the same time. If you buy the second 2
band module for 20/40 you will have to remove the 80/15 module to install
the 20/40. You will also need to reprogram B1 to 14 and B2 to 7. Every time
you remove one band module and install another you should go through the
menu to change B1 and B2 to match the installed module.

Roney,

When you change band boards, you will have to enter the menu and change
the "b1" and "b2" parameters to match whichever bands you have on the board.
b3 and b4 are only for the 4 band board which is no longer available.
The 2 band board only allows "b1" and "b2".

The K1 does remember the CAL OPF offsets for up to 6 bands, so if you
set that up initially, you will have correct calibration and frequency
display.

Between 2002 and 2014 Elecraft made a four-band filter board KFL1-4 which allowed operation on 40m, 30m, and any two of 20m, 17m, and 15m.  It had superior RF performance on each band compared to equivalent two-band filter boards.  The unavailability of special temperature-stable trimmer capacitors forced its discontinuation.  It was a gem, after its design was altered to use those capacitors, and backfit kits to older boards became availble.

So when you read of a four-band K1, the discontinued KFL1-4 is what made it possible.
