[Elecraft] RSP-1A as panadapter

[Richard Ferch]

I use an RSP2 as a panadapter. I can feed it either from the K3's IF Out
connector, in which case no protection is needed, or from the K3's RX Ant
Out connector, in which case it is protected by the K3's T/R switch. In
both cases there is a signal present on the SDRplay's input during
transmit, but it is at a low enough level that it is not a concern.

The connection to the RX Ant Out connector is actually a jumper from RX Ant
Out to a splitter plus jumpers from the splitter to the RX Ant In connector
and the SDR's antenna input The splitter I use is actually just a UHF tee
with UHF-to-BNC cables. The K3's RX Ant needs to be engaged to use this
path. This makes using a separate RX antenna somewhat more complicated.

For those of you using an SDRplay as a panadapter with the K3S, what RF
protection do you use for the SDRplay?
