so ive been messing with this for about three weeks now and cant quite nail down what's happening. running a remote station through RemoteHams with an RTL-SDR feeding the panadapter view to clients, and everything looks fine until i switch bands — like if im on 40 and jump to 20, the audio just cuts out on the remote end. the radio itself (IC-7300) seems fine locally, no issues, but the client side just goes silent and they have to disconnect and reconnect the session to get it back.

i thought at first it was a latency thing because the upload on my end is only about 12 Mbps which i know isnt great for this, but even with one client connected it does it. tried adjusting the audio buffer settings in the RCForb client and that didnt seem to help either. someone mentioned it might be a VSPE conflict with the virtual COM port but i havent gone down that rabbit hole yet.

also tangentially — has anyone done internet linking through this same setup? like running an Allstar node or IRLP alongside the RemoteHams instance? wondering if sharing the audio device is whats causing some of this weirdness actually.

the band switch audio drop is almost certainly a sample rate mismatch or the SDR is reinitializing when the 7300 changes its IF output characteristics. some rigs do this, the 7300 especially when you switch between certain band segments because the internal routing changes slightly. what software are you using on the server side to bridge the SDR to RemoteHams? if its SDR# or HDSDR there's a setting for locking the sample rate that might help. also check if you have VAC or VB-Audio pipe in the chain because those virtual cables sometimes reset on device state changes.

on the allstar question — yeah i run both on the same machine but i use a dedicated USB audio interface for allstar and keep the SDR on its own device, never tried to share. mixing them sounds like a headache honestly.

had something similar a while back, turned out to be the RemoteHams server software losing sync with the CAT control when the band changed and it was basically confusing the audio routing. upgrading to the newer RCForb server version fixed it for me, not sure which version you're on but worth checking. also 12 up should be fine for this, i run mine on way less and its okay as long as noone else in the house is streaming.
