Works, but theres a catch. Time Owned: 0 to 3 months.
I bought this isolator in order to help stop RFI coming from my computer's USB ports from being injected into my IC-7300 and thus raising my noise floor. When i plugged the isolator into my computer, Windows(Windows 10) alerted me that the last device that i plugged it had malfunctioned and i also noticed a large, slow moving birdie appear on my 7300's waterfall(I'm not sure the distance between each birdie but the birdie's amplitude was significant). However in the process of all of this happening it did seem to reject the hash coming from my USB ports(either that or the isolator wasn't allowing a proper handshake between my 7300 and my computer and thus nothing was being sent to my 7300). Due to the fact that the 7300 is a SDR transceiver, i would be interested to see if the isolator would also cause birdies to be received by other radios such as the FT-891 which is not a SDR transceiver just for experimentation purposes.

Works like a charm! Time Owned: 0 to 3 months.
So folks this was the problem...My motherboard on my PC died, so I replaced it.
Now my Icom IC-7600 would disconnect from the PC if I transmitted more than 10W from it, even into a dummy load so it's not RFI in the shack- obviously a sensitivity issue with the new motherboard.
I was able to tie the PC's chassis ground to the radio's ground to eliminate the ground loop, but then I got tons of RFI noise coming over the radio's waterfall. This is a NO GO workaround situation because I could either transmit or receive, but not both depending on if I tie the ground or not.
I decided to take a nap and think of a solution and Google came to mind.
So after the nap I googled USB ground loop isolators and this was one of the cheapest ones available. I figure for $19 I'll give it a shot, if not, I'll toss it in the junk drawer for some other obscure use.
Well folks now I am buying more for the junk drawer because these things totally rock!
Full 100W transmit, no comm disconnects!!!! No nasty vertical bars on my waterfall!!! Totally awesome!
100% operational now!!!
I'll also point out that the two I got are covered with some clear heatshrink versus what the picture advertises as a open circuit card.
No drivers required as it is transparent to the PC. Plug it into your USB port, plug your radio or other device into the USB socket on this isolator and Cash Money you're in business!!
Thank me later!
This card does have a little blue on/off switch on it. I don't know what it does.
It does have a isolated 5V power supply built in on the board too for powering devices up to 1W, so wifi cards that get their power from the PC will probably not work.
In god we trust, all others we monitor- 73 de AD0AR
