RemoteHams SDR setup - latency issues or am I doing something wrong

 Loading...

so ive been messing with RemoteHams for about three weeks now trying to get my home station accessible from work and honestly its mostly working but the audio latency is driving me nuts. like there's probably 600-800ms of delay which makes SSB basically unusable, CW is just... not happening. i run a IC-7300 at home with a pretty decent upload, around 25 meg up on a cable connection, and the client side at work is on a corporate network which is probably the issue but i cant prove it.

has anyone had luck tuning the buffer settings in the RemoteHams client to get latency down? i saw something about changing the audio buffer size but every time i mess with it i either get dropouts or it makes no difference at all. also wondering if this is even the right tool for what im trying to do or if i should look at something like SDR-control with an SDRplay hanging off the home machine instead, at least for receive monitoring. the full TX control would be nice but honestly right now id settle for just being able to listen to 40m during lunch without it sounding like im talking to someone underwater

any thoughts appreciated, been a ham for about 12 years but remote ops is new territory for me

corporate networks are almost always the culprit, they do all kinds of weird QoS and traffic shaping that murders real-time audio. the buffer settings in RemoteHams wont save you if the network itself is adding jitter. i had the same thing at a previous job, turned out their firewall was doing deep packet inspection and basically treating the UDP audio stream like garbage tier traffic.

one thing worth trying is see if you can get the RemoteHams client running over a VPN that routes around the corporate filtering, though obviously that depends on your work situation and whether thats allowed. if you just want to monitor i honestly think youre right to consider the SDR route, just spin up SDR++ server at home and connect to it, the overhead is way lower and you can tune it aggressively for bandwidth. TX remote is a different animal and RemoteHams is still probably the better path for that once you sort the network side out.

yeah the 7300 works pretty well with RemoteHams in my experience but 25 up should be plenty, sounds like its def the work network. i run mine on a basic cable connection with like 10 up and SSB is totally usable from home to home, maybe 200ms ish which isnt perfect but workable. never tried from a corporate connection tho so cant say for sure thats it.

one thing i never see people mention is the CI-V settings, make sure the baud rate between the 7300 and whatever youre using for the serial bridge is maxed out, slow CI-V can add weirdness to the control latency separate from the audio thing. probably not your main issue but worth checking if you havent
