This a screen shot of a local 2m beacon at 123 miles from me.
I have tried to set the display on SRC Console to be as close to identical as possible and they were received on the same computer running two instances of SDR Console.
The left hand side is the Lime the right hand side is the FCD+. I use a FCD+ as my test RX as IMO it is a very good weak signal RX on 2m. the only better RX I have is my Kuhne but I could not easily set that up for a side by side.
Settings…
Antenna is a M25WL on a 8ft test tower and NOT aimed at the beacon but slightly off to reduce the signal. The coax goes to a WA3LBI 6 pole 2m BPF and then into a Mini Circuits 2 way power divider feeding the Lime and the FCD+
Lime settings are built in LNA MAX External ARR LNA.
FCD+ built in LNA 0 and no External LNA.
This is not a lab test but just a real world test. I think I managed to get them pretty close on settings by eye. Anecdotal comment. The lime in this picture is about as good as I remember when comparing a TS2K to the FCD+. If I recall correctly I had to have and internal Pre amp and the same external LNA in inline for the TS2K to be equal to the FCD+ on the SDR Console waterfall. Again that is from memory and not a lab test. My view is based on what I think the average Ham will hear (or see) when connecting a radio up. I will leave the lab reports to those who can perform them better than I.
