Elecraft 70cm transverter, K3 and repeater access tones?

[K2QI]

Dear group,

 

I'm curious as to how this would work.  Say I have an Elecraft 70cm transverter connected to my K3.  I'm assuming that if I wanted to use the transverter to communicate with UHF repeaters I would select the transverter via band button, set the mode to FM and select proper tone, set power output on the transverter to 10w or less, and the transverter will do the rest?  I've never used a transverter before, so I apologize if my question is a stupid one.

 

73,

James KC2UEE

Yes, that's what you would do. Except you forgot to set the repeater offset (RPT OFS in the menu.) I don't know how you would get the K3 to select a CTCSS tone, though. If there is an option for it, I can't find one.

In FM mode, hold PITCH.  Select the CTCSS tone with VFO A and
enable/disable with VFO B.

Got it! Serves me right for looking for "CTCSS" in the index of the manual.

Hi David,

Thanks for the information.  I didn't realize that the XV432 didn't cover
the whole 70cm band.  This is good to know, as I intended to use the
transverter to communicate with local 440 machines.  I suppose it would be
better for me then to go with the XV144, or just buy a 2m/440 base instead.

Hello James,

Repeaters on 10m and 6m are well within the K3's abilities.  A K3 with
XV144 (or any other 2m transverter with a 116MHz local oscillator) will
cover repeaters between 144-146MHz.

But 70cm is a bit of a problem.  A K3 and XV432 will only cover 432 to
434MHz in stock form.  In VK our repeaters are around 438 to 440MHz with
a -5MHz offset.  So with a K3+XV432, I could transmit into but not hear
anything from them.
One wish/suggestion I have made before is to modify the XV432 for a 6m
IF.  This would give it a 6MHz range. I have set up my lesser quality
homebrew transverter this way and I get 432 to 438MHz - ideal for my
main interest in satellites, but still not quite there for my local
repeater.

Hope this helps.
