144mhz transverter

[Robert 'RC' Conley]

I am in the process of building a 144 mhz transverter for use with my K3/10.
I'll use a 116 mhz "LO" and the 28mhz "IF" of the K3 for this purpose.
Do I need to obtain an upgrade circuit PCB's from Elecraft?  My K3/10 does not
have any additional options.

Thanks you help is appreciated

You will need the KXV3 (or KXV3A) transverter interface. It's a plug in
board that is easy to install, see the download version of the manual
for it.

This is not strictly true. If you can lose the 10W in an attenuator you can use the K3 just like any other radio to drive the transverter. But I agree the best thing to use is a KXV3A. This gives you the connections you need. One thing you will not have is the control provided by the Elecraft auxbus. I know it is expensive andnot really a technical challenge but you might be better off buying the built in 144MHz transverter. If you want a technical challenge, I am sure you can find another one.

RC,

I assume this is a homebrew transceiver or some other non-Elecraft kit.  
If so, does it have a single 28 MHz port, or does it have connections
for split TX and RX.

If it is a single 28 MHz port, then you can connect it to the 10 watt K3
output and use an attenuator that is only in-line during transmit - it
would take an extra relay to switch the attenuator in and out, but it
can be done.  The attenuator should be able to handle the full 10 watt
power from the K3.

If you have split TX/RX on the transveter, the easiest solution is to
add the KXV3 or KXV3A (current model) to the K3 and use the split drive
- that way you will not have to change the HF antenna connections to use
the transverter.
