[Elecraft] VFO tuning range of 150Khz

[Mike WA8BXN]

Hi Joe, 
 
Long ago when I got mine I chose to have my cake and eat it too. I built it
for 150 KHz but put a tiny dpdt switch on the back panel that allowed me to
put a resistor in series with the tuning pot at one end or the other
depending on switch position. The added resistor was the same resistance as
the pot as I recall. This halved the tuning range of the pot. Depending on
which end of the pot the added resistor was would resulting in tuning the
top or bottom half the the 150 KHz tuning range.

I've had a couple of K1's but I am actually constructing my first one from a

Kit. I need to decide whether to set the VFO range to 80 or 150Khz. I am 
Leaning toward the 150Khz because occasionally I like to go up to the slow 
Speed CW portion of 40 (7.110-7.125 Mhz) and also because it would be nice 
To receive WWV at 10Mhz. Every K1 I've had to date has been set for the 
Narrower tuning range. 
 
I need to make the decision quickly since I'm about to choose which crystal 
To install for 30M. If you have a K1 that tunes 150Khz how do you like it? 
Do you find that the tuning is too sensitive and do you wish you had set it 
To the narrower tuning width? 
 
Thanks. 
Joe
