The G4HUP designed buffer amp is now being sold by SDRKits in the UK if that helps.

I had a reply from Radio Analog:

Hi Frank,

Thank you for your interest and we appreciate your valuable feedback.
As you see in homapage text, we mentioned that ICOM-7300 is direct sampling receiver. We know that there is no frequency conversion but actually we havent find better term than IF and supposed every amateur know how their rigs works already. Taking your feedback seriously we are going to add a short explanation.

Keep watching website for updates please.

Kind regards,
Radio Analog Team.

@VE7BPB

I had another look at the PTRX-7300. I think I get it now. The following features are of interest:

Dual Receivers Mode: YES
Simultaneous Operation: YES
RX/TX Monitoring: YES
SDR Port to RF tap Point Isolation: High (>60 dB (average), Amplifier Reverse Isolation)

If you are getting one, please let us know how it performs in actual use.

 

For me, this solution is too restrictive.
Having the band pass filters in line will no doubt help a cheap SDR dongle but this comes at a cost.
The band pass filters restrict any second RX's usefulness to the band currently selected. With the higher bands, the filter bandwidths are greater but operating on say 80m, the 2nd RX could not be used on a different band.

Having two receivers on the same band is not something I need.

Hmm, i'm fairly tempted to try one out with my SDR Play.

 

My main rig is a Flex 6400, but I also own am Icom IC-7300 and and SDRPlay RSP1A receiver. When working DX pileups, I often use the Flex's second receiver slice to listen to the stations calling the DX. This usually help me figure out the split more quickly than just parking on a clear spot and calling blindly. I never really use the second receive slice to listen to another band, so the PTRX-7300 might allow me to the same thing by using my RSP1A as a second receiver with the IC-7300.

I would love to see a review on PTRX-7300 and see if this works as advertised. This might not be a bad upgrade for my style of operating.
