Differences between ports A & B
Differences between ports A & B
Is it safe to assume that HF performance on ports A & B should be the same? I'm receiving fine on port B, but port A is dead on HF. Identical gain settings, etc. Port B is working fine on VHF. Is this typical behavior?

Hi Paul. A and B are exactly the same on my RSP2, both work on HF and VHF/UHF. Don't forget you have to select them with the switch on the MAIN panel.

Re: Differences between ports A & B
Thanks - that's what I expected. I've got a new unit and am wondering if there is something more nefarious going on, when switching the same HF antenna from port A to port B, and leaving all settings the same except changing the antenna port in SDRUno, I'm getting very different results.
I'm going to toy with this more tonight and make sure I'm not overlooking something silly.

Re: Differences between ports A & B
There should be no differences between port A and B...
- when you don't forget to switch to the input your antenna is currently connected to,
- and your frequency is still the same, above 1.5MHz,
- and you remember checking if RF gain and IF gain are producing the same gain/gain reduction (which may change when you switch a number of things, which is a bug currently being worked on).

Thanks all - I did more testing tonight and am noticing port A is deaf on HF, and weak on VHF when compared port B. Identical settings, antenna, coax, ect., except for switching the antenna connector between ports and changing to the correct antenna in SDRUno. I've also noticed that my HI Z port is pretty much deaf, with a 50' random wire I'm not even picking up AM broadcast stations at any gain.
I sent a note to the good folks at support and will see if they have suggestions.

That sounds a bit like something went wrong when you installed SDRuno (which also installs the hardware drivers for the RSP2), Besides contacting support I'd start with disconnecting the RSP2, then rebooting the computer and reinstalling the latest SDRuno version with the device still disconnected.

If a reinstall doesn't work, perhaps undo the case and check the port A cable didn't come loose from the board, they are connected using u.fl connectors...

Hello!
I have exactly the same problem with ports that you described in this thread. Tell me, please, how did you solve this issue?

Re: Differences between ports A & B
Hi guys, there is a very well known bug with SDRplay, when you change the antenna input connection, sometimes the software does not respond and you have to switch again among inputs until it "takes". Perhaps this is the difficulty you have, as there could be a max imbalance of less than 1 db among inputs. If difference persists, you should open a ticket as sometimes one socket starts turning and gets disconnected (happened to me).
