Is the issue of frequency accuracy, plus stability, not a consideration when attempting 60 meter operation with a 4-line? Changing PTO frequency would still result in one having to deal with accuracy and stability issues which, for channelized operation, are more critical. Just some random thoughts...

It will work to use a 16.1MHz crystal. You will get images and spurs though. If you are lucky (I haven't run the numbers) they are far enough from the 60m channels to let you RECEIVE them... BUT do not try to TRANSMIT, you will put out spurs that are out of the ham bands. IF, PTO, mixing products, who knows what... ;-) 73, Gary WB6OGD ----- Original Message ----- From: Charles Ring <[email protected]> To: Edward Gable <[email protected]> Cc: [email protected] Sent: Tue, 27 Nov 2012 17:12:55 -0000 (UTC) Subject: Re: [Drakelist] 60 Meter Operation I see that a 16.1 MHz crystal would cover 5.0 to 5.5 MHz if it can work at all. With the 60 meter channels ranging from 5.3305 to 5.4035 MHz, I wonder if at least receiving might be possible? 73 de W3NU On 11/25/2012 1128, Edward Gable wrote: Hello Bob: If you look at any of the 4 line manuals you will not see an external Xtal listed for the 5 to 6 Mhz region. Me thinks that is because of the VFO operating at 5 Mhz and thus there is no mix that will take you to the 60 meter band. So other than a fairly major circuitry change I don't think it's feasible.
