[Elecraft] K2 user-interface quiz -- my answers

[Wayne Burdick]

There were lots of creative QSY techniques suggested in answer to my quiz question:

> Suppose you're on 17 meters, with your K2 display showing 18105.00 kHz. 
> Using front panel switches only (no knobs), how many unique ways can you 
> QSY down in frequency by at least 5 kHz? There are at least 12 ways, 
> each totally different from the others.

Several respondents came up with 8 or 9 good answers. But since noone got all 12 that I
had dreamed up, here they are. Note that I interpreted "QSY" loosely: receive or transmit.

Obvious ways:

1. tap VFO A/B, with one VFO set at least 5 kHz lower than the other
2. hold VFO REV (temporary A/B switch)
3. recall a memory
4. direct frequency entry
5. tap band down
6. scan resume

Tricky ways:

1. in SPLIT mode, play back a message buffer
2. if +/- 4.8 kHz RIT range is selected in the secondary menu,
   and the RIT knob is fully counter-clockwise,
   tapping RIT will change the frequency about 5 kHz
3. same setup as #2, but tap XIT, then play a message buffer
4. if you had just turned the VFO *up* to 18105 from some
   other frequency, but didn't wait 30 seconds for the
   backup timer to save the new frequency in EEPROM, 
   turning power off/on would bring you back to the
   lower frequency (last one stored)
5. reset to defaults (4+5+6 on power-up); puts you on 40m
6. select CAL FCTR from the menu, then tap BAND-, which
   shifts the PLL reference oscillator to its lowest frequency,
   which would move you well over 5 kHz on 17 m

Bonus, extra tricky:

   If you had transverter band TRN1 set up with an I.F.
   of 10 m, and band TRN2 set up with an I.F. of 20 m,
   and TRN1 with an *RF* band of 18 MHz, you could be 
   be displaying 18105 with TRN1 selected but hit 
   BAND UP and be on some lower frequency.


If you read through all that, thanks! You're now qualified to suggest future K2 UI Quiz
topics  ;)  Please send them to me only, not the list.
