KBPF3 Query

[alsopb]

Guys,

I was wondering just how this works.  Suppose one wants 9 MHz.  Does one
set the band to 30M and just tune down to it?  Does any of this confuse
the band selection via buttons?   Alternatively if one sets the
frequency with the key pad, what "band" does it appear in.

I seem to recall some unintended consequences reported here a long time ago.

In this case, I just key it in.  The band will change to 30-meters and if you cycle through the bands, the next time you hit 30-meters you will be set to 9 MHz.

BTW, I have my M1-M4 memories set to "default" frequencies for each band so that M1=CW, M2=SSB, M3=Data A (PSK) and M4=AFSK-A (RTTY). So when I get some oddball frequency/mode set on a particular band, I can quickly recover to a known state.

Hi Brian,

This came up and was discussed on Nov. 15, 2009 with a thread titled  
"K3 Firmware Req for SWL band and Using Memories"  Search for that  
thread in the archives to read all the gory details.

The key information that's missing from the documentation is the band  
edges.  I determined them experimentally to be:

160m  0.5 -  2.999999 MHz
  80m  3.0 -  4.799999 MHz
  60m  4.8 -  5.999999 MHz
  40m  6.0 -  8.999999 MHz
  30m  9.0 - 12.999999 MHz
  20m 13.0 - 16.999999 MHz
  17m 17.0 - 18.999999 MHz
  15m 19.0 - 22.999999 MHz
  12m 23.0 - 25.999999 MHz
  10m 26.0 - 30.000000 MHz
   6m 44.0 - 54.000000 MHz

To answer your specific questions:

You can, but I usually punch in the frequency I want, or one close to  
it and tune from there.  E.g. if I wanted 9 MHz, I punch that in: FREQ  
ENT > 9 > AFX (the AFX key is also the "ENTER" key).

No.  Not as long as you keep in mind the table above.  If you're at 9  
MHz, you're on the 30m band.  If you then go to 15 MHz, you've  
switched to the 20m band.

See the table above.
