I recently bought an Expert Electronics ColibriNano for use primarily as a Panoramic display from my K3S.
My laptop has the correct version of EESDR2 software, the SDC program, Omnirig, N1MM, VSP Manager.
I was referred by Roman to this old document from Yuri UT4LW which was for the Colibri DDC receiver but he said should work the same with the Nano.

I followed the link instructions but they failed to work for me. I’m lost I think in the realms of the SDC program in the Rig Sync tab & the COM Spider tab.
One of the things I’m not sure about is the connection to the laptop. I’m using the K3S IF output to the Nano antenna input (This can be used for the Elecraft Pan Adaptor the P3, & I’ve also seen it used with SDRPlay receivers) plus the K3S FTDI USB cable to the laptop USB Real port COM3.
The Colibri & EESDR2 are both working fine if I connect an antenna directly to the NANO. But I cant yet get it to read the frequency mode etc from the K3.& work with N1MM

Hi, Ray.
At the moment ExpertSDR2 doesn't support synchronization while IF receiving, because IF doesn't equal tuning frequency.
You can commutate ColibriNANO with K3S on the antenna input, this way receiving will happen with ColibriNANO and TX with K3S, frequency sync will happen via CAT.

When we implement transverters it'll also allow us to add support IF output for such occasions.

Thanks Roman.I'll try using the RX antenna Input & Output of the K3S with a Tee piece BNC adaptor to feed the Nano
I have also asked Yuri who said "don't use the IF output of the K3"

Hello,


i have the same problem. I cannot use the IF of the K3s to connect the colibrì, but the RX OUT ANT of the K3s doesn't mute the receiver when in TX.
So, which is the solution used by yuri or Ray (if solved) ?
I can't figure out how use the Colibrì as a pandapter (with sdc features) without use the K3s IF...

Any help ?

Thanks, Graziano IW2NOY
