K3 and Javornik II transverter

g0afh
Hi,

Is anyone here running a Javornik II 2m transverter with their K3? just
wondering how well the two perform together.

Hi Dominik,

Thanks. I already have the Javornik which is currently used with my
Ft1000MP. Just thinking about an upgrade...

Hi Jeff

Thanks. I already have the Javornik.

Out of interest, can you split the TX/RX paths on the K144XV? I need to
add a couple of filters in the receive line to keep some fairly big
local signals out.

Re: K3 and Javornik II transverter

Hi Dave

Thanks for the info. That should all be fine.

On the K144XV can the TX and RX be split at 144MHz? That is where I need
to add the extra filtering.

I presume that the second RX is still available as a separate input when
using the transverter interface? The Javornik transverter has two
receive converters.

Re: K3 and Javornik II transverter

g0afh
Hi Dave,

Thanks. I think I may have created some confusion here too!

My transverter has two receive converters, i.e two 144MHz antenna inputs
and two separate 14MHz IF ports. In normal operation I want to run with
one receive converter on the K3 main RX, and the other on the K3 sub.
With two antenna arrays I can have one ear on the UK, the other on
Europe. I can do this now with my modified FT1000MP but the 1000 lacks
some of the niceties that the K3 has like being able to synchronously
tune both receivers.

I think that this should be possible with the K3 as it's just like
operating it on 20m using diversity reception and transmitting at a few mW.
