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.

Re: [Drakelist] 60 Meter Operation
The T-4X IF frequency is 5645 khz, that’s why the manual states not to use the frequencies 5 to 6 mhz. 73, Gary ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
Re: [Drakelist] 60 Meter Operation
Like another Gary pointed out, the IF is in the way. 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 w...@roadrunner.com To: Edward Gable ega...@rochester.rr.com Cc: drakelist@zerobeat.net Sent: Tue, 27 Nov 2012 17:12:55 - (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.

Re: [Drakelist] 60 Meter Operation
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... 73, Evan -Original Message- From: Gary Winblad garywinb...@comcast.net To: Charles Ring w...@roadrunner.com Cc: drakelist drakelist@zerobeat.net Sent: Tue, Nov 27, 2012 5:58 pm Subject: Re: [Drakelist] 60 Meter Operation Like another Gary pointed out, the IF is in the way.

Re: [Drakelist] 60 Meter Operation
If you wanted to 'speriment, one might be able to switch the VFO directly in, or simply turn off the het osc so the VFO blows thru the mixer. I can't recall if there is a trap for the VFO freq after the mixer but if you really need to get on 60M, it might work. I have been playing on 60M during the evenings here and find it quite pleasant. Both CW and SSB. FWIW Curt KU8L On 11/25/2012 11:28 AM, 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.
