No Transmit Audio on 7300


I’m having no success in getting transmitted audio out to the radio from either the client here on my Lan, nor another windows client out on the network. I’m getting control, PTT and all other controls on the View panel , panadapter waterfall are
I’ve gone back over the manual settings on both the server and client pcs. I’ve set the radio settings exactly as described in the manual as well. Still no mic audio. Mics show working in Windows 10 sound settings as well.
Using ver 1.2-e
Port forwarding on 5001-5003 in router pointing to the radios ip.

Radio status panel shows mic activity.

One other thing, from the client laptop I can hear mic audio from the server location over the receive audio.



On the machine connected directly to the IC-7300, wfview only uses audio for the server, it doesn’t really make sense for wfview to do anything else with audio devices as the radio must be close to the computer to work. You are best to leave the ‘main’ audio input/output comboboxes on the default audio device. The USB Codec devices need to be selected in the server tab to allow server audio to work.

Thanks for the quick reply,
I thought I was following the manual in setting this up.I want my client on the Internet to be able to use the 7300 and be able to receive and transmit audio from across the hall web to my 7300
Can you refresh me on those settings both server and client? The server It’s set up right next to the radio on a Windows PC. The client could be someone on the land, or the Internet. I’m just not clear on this. Thank you


Did you ever resolve this, I’m having the same issue.


Hi Mike:

I’m having the exact same problem with my 7300 connected to Win4ICOM over my LAN. PTT works fine, but I don’t seem to be getting any audio out from the mic.

Doesn’t look like you got a response on your question. Did you get it figured out?

Hi Ron,

Give wfview a try without Win4Icom running. wfview has built-in remote audio and control. This is a configuration we support. You’ll need one copy of wfview running on a computer with the 7300’s USB connection, and the second copy can be on a remote computer or laptop connected via the LAN or internet.

See here for details: Remote Operation (server) | wfview

If you get that working and then decide you need win4icom at the same time, we can try to see if there is a way.

Generally “no transmit audio” means the radio’s transmit audio source is set incorrectly, for example, set to “Mic” instead of “USB”. You can change that setting in the radio’s menus or within wfview.
