Hello WDXers,
I'm running a SDR setup on RX and using a cheap PTT relay switcher box to TX with an IC-7300. It's so cheap, it's craptacular. TX bleeds through the SDR and it's fixing to eventually fry its input stage. And it starts to go bananas after a while and I have to "reset" it by unplugging it. Anybody got suggestions on something that has proper shielding and doesn't cost 500 bucks? Preamp would be nice but not necessary.
Obviously it has to work in the HF range, 100 Watts minimum.
The junk I got:
What I would REALLY like (local to me, like a twenty-minute drive, but the guy doesn't make them anymore)

Might consider these, but no idea on its innards. Anybody try these?
Interesting but expensive. There's also a no-preamp version. Still no idea on quality but some say it has as much as 100 dB isolation.

I'm open to info and suggestions here.
Cheers, mates.
