You really don't need to change the crystal, unless you want to receive WWV @ 10 mHZ. It would be easier to leave the crystal as it is, in case you go back.
As for the filters, if you leave them alone nothing will change on the band segments you currently use. On 40 meters, you may want to peak the filter a little higher at maybe 7.070 mHz. Since you probably won't use the extended range on the other bands, you can leave them be. It is a bit touchy to tune, but then I like the ability to get to the old 40 novice band. If you just do the VFO, it is easy to go back. If you like the change and want WWV, you can do the crystal later. -- View this message in context: http://n2.nabble.com/K1-VFO-Range-Question-tp4580754p4581499.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
