Installing a Sub Receiver

I put it off for years getting the Sub-Receiver for my K3.
With the change to K4, I got a sub-receiver before they become unavailable.

The sub-receiver comes with the KSYN3A synthesizer board --- so it occurs
to me to change that board into the primary receiver and use the older one
with the sub-receiver. That may make it easier to change out later.

I am really so impressed with the K3 receiver after about 6 years that the
new synthesizer always seemed pointless -- but now I have one anyway.

Re: Installing a Sub Receiver

The two synthesizers must be the same. You will actually need to replace your older synth with another KSYN3A.

Both receivers have to use the new synthesizer board. You can't install
them in the way you've described, unfortunately.

Re: Installing a Sub Receiver

Thanks everybody.
The sub-receiver came with the new board, but with all your good advice I
just ordered the KSYN3A board and will come soon.

Only one downside: It is a rainy day here in Middle Tennessee ---- it was
a perfect day to stay inside and get this done.

Installing a Sub Receiver

In reply to this post by Ted Edwards W3TB

It seems the OP has it covered, but, if one isn't ready to spend on the new synth, one can get an old synth for next to nothing and run with two old ones.
The upgrade isn't a big deal for most ops.

Re: Installing a Sub Receiver

Ted,

The new synthesizers give the K3/K3S a vast improvement in transmit
phase noise, as well as improving the receive noise floor performance by
several dB.

Both synthesizers must be the same.

I would highly recommend getting another KSYN3A board to use in your
main receiver to match the one supplied with your KX3A.
If you anticipate using Diversity mode, it is a necessity.

If the filters in your KRX3 do not match the ones in your main RF board,
then the new synthesizers are a MUST - the new synthesizers can work in
diversity mode with unmatched filters, but the old ones cannot.

73,
Don W3FPR
