If the trx duo also has a high impedance at the input and the capability of 8 slice rx, in my opinion it is insufficiently competitive with the RP14. Regarding 1:14 professional input transformer: on my RP14, significantly better reception is achieved with the 3/22 turns transformer on the BN73 202 . 73, all the best and HNY Niko, S53A Ps. Pete, Thank you for your hit about frequency shift on s53a skimmer. I immediately ordered GPSDO, but transport in UK is still on strike. Still waiting? ?

I think anything with TRX-DUO name is the same device. The ZYNQ7010 is what limits it to one 8 slice Rx as the memory is smaller if I remember correctly. 73 de KV4TT Mike On Dec 31, 2022, at 8:49 AM, Pete Smith N4ZR > wrote: ? There seem to be several clones available from Chinese sources. It would be helpful for reviewers to specify which is which. 73, Pete N4ZR On 12/31/2022 8:36 AM, Mike Zabel wrote: Hi Niko, Yes I have tried one here. It runs only the 14 bit apps from Pavel, so only 8 band capable. Even though it?s 16 bit it has a less capable FPGA installed. The hardware seemed a little less sensitive on Rx than the two 16 bit RP I have been running. It?s good for the price, especially since the price has gone up on the Red Pitaya ?
