so ive been messing with remote station control for a few months now and finally got my IC-7300 accessible via RemoteHams but now im trying to figure out if theres a sane way to also link it up with some kind of SDR frontend for panadapter view when operating remotely. like ideally id have the main rig controllable plus a wideband SDR running on the same machine at the shack end feeding a spectrum display back to my client side

the latency thing is obviously a concern, my connection at the shack end is about 50 down 10 up on a decent day but its a rural ISP so it varies. RCForb seems like it handles audio compression reasonably well but im not sure if adding an SDR stream on top is gonna kill everything

anyone actually running this kind of hybrid setup? specifically curious if youre using a separate SDR like an RTL-SDR or an Airspy tapped into the IF output vs just relying on the rig's own spectrum scope over the remote software. the IC-7300 scope over RemoteHams is pretty laggy for me and barely usable honestly

yeah i ran something similar for about a year before i upgraded the shack end internet. had an RTL-SDR V3 tapped into the 7300 IF out and was trying to stream that back using SDR-Console's network server mode alongside the RemoteHams audio. honestly it was a mess at 10up. the SDR stream alone was eating like 2-3mbps even with compression cranked down and then you add the audio and control channel and it just got choppy

what actually worked better for me was dropping the SDR sample rate way down and using a narrower chunk around whatever band i was on rather than trying to stream the whole HF range. if you just want a panadapter centered on 40m for example you can get away with a much lower rate. still not perfect but usable. Airspy HF+ would probably behave better than RTL for this since the dynamic range is way better and you need less of it to see whats going on

the IF tap on the 7300 is pretty straightforward btw, theres a thread on eham somewhere about the exact connector location

cant really speak to the SDR side but on the RemoteHams latency thing - have you tried the RCForb client versus the browser interface? the native client handles the audio buffering way differently and i found the scope data was a lot more responsive when i switched. the browser version was driving me crazy, kept getting that half second freeze on the spectrum display

also 10 up should be workable for basic remote ops, i run my station on similar and its fine for voice and even some slow digital. might wanna look at what else is happening on that connection at the shack end, sometimes its a router QoS thing not the raw bandwidth
