I recently received a message from a list member telling me that
he was planning a trip to the Deer Lodge area of Western Montana. Now I can't find the message and I'd like to welcome you for a visit. Rose would enjoy showing you her sewing room, better known as Rose's Cases and Covers. 73!

Howdy All,
Started building my Elecraft K1 this evening. All is going well, so far, with the KFL1-2 board. Just finished installing all components up to the toroids on the 40 meter band. I am confused about the 80 Khz or 150 Khz tuning range setting. Is this for 30 meters only or for every band? I installed the 15.000 Mhz crystal for 40 meters at X1. Will the tuning range be 80 Khz or 150 khz? The manual says the most used portion of every band for the 80 khz setting. I am confused about how to set that on the 40 meter band. Thanks 73 Thom KI8W ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |
Thom,
The 80 kHz or 150 kHz is the range for all bands. For most bands, the active CW portion is within the first 80 kHz of the lower band edge, so there is no need to be concerned about which crystal will be used. However, on 30 meters, if you choose to use the 18.000 MHz crystal so you can tune to WWV at 10.000 MHz, then with the VFO tuning range of 80 kHz, you will tune from 10.000 to 10.080 kHz which is always below the 30 meter ham band (10.100 to 10.150). So if you choose the 80 kHz VFO range, you must use the 18.100 MHz crystal so the tuning is from 10.100 to 10.180 MHz (greater than the 30 meter band high frequency). If you choose to use the 150 kHz VFO range, you will want to use the 18.000 MHz 30 meter crystal since you can tune to WWV on the low end and also tune the entire 30 meter ham band since the high frequency on 30 meters will be 10.150 MHz or greater. With the 150 kHz VFO tuning range, the tuning will be a bit more "touchy" than with the 80 kHz range because each turn on the VFO knob covers twice the frequency variation. The choice is yours. Looking at it the 'other way around' - if you want to cover the 40 meter band from 7.000 to 7.150 MHz to work those stations that work in the old novice portion of 40 meters, then you would choose the 150 kHz option. It does not matter much on other bands (except 30 meters) because most CW activity is in the lower 80 kHz of the band. 73, Don W3FPR On 5/12/2017 11:23 PM, Thom wrote: > Howdy All, > > Started building my Elecraft K1 this evening.
