I tried my HD in the house with a spare car ant. Works great, but get a slight buzz from the speakers. Gonna try the grounding thing.
just for the record... i applied the grounding fix to my rca's before i ever tested the unit out. then, i ran into my ridiculous interference issues and in turn removed that connection.
then i fixed the interference problem...
for some reason, i cannot tell any noticeable difference between the grounding fix and without (i.e. im really not getting any extra noise)
didn't know if anyone else might have had the same experience. how noticeable was the noise anyways?
EDIT: I only removed the "grounding fix" among other things while I was trying to solve my interference problems. It did not actually solve the interference... just for clarification
This is exactly what I'm doing. I have manual KVM switch laying around you know :rofl:, but I better off getting some relays ;).Quote:

I experimented with ferrite split beads, torroids, sealing up the case better, etc.
I finally got something that seemed to work... which was a combination of: having the pc case as sealed as i could get it, putting ferrite torroids on the 12v constant and 12v switched lines as close to the psu connection as possible, placing a "antenna noise eliminator" that i got at Fry's inline with the antenna connection, AND putting ferrite split beads on mitch's cable because i was then getting interference across the serial cable.
it was sick. but it seems to work.
by the way, the "antenna noise eliminator" was nothing more than a black box housing an LC circuit in parallel with the +/- antenna connection...
my only point about the RCA grounding was that i couldn't tell a difference with/without it after i had my radio working..
My tuner is ground referenced to my carPC chassis, which all my PCBs are grounded to and I have no noise issues with a straight forward simple install.
Mitchjs, Let me know when you have more cables available, I am going to order another HD tuner for testing/developing on the desktop, its much easier than software programming on a 7" screen :)
yeah, I'd like to know when the cables are available again too, a little late to this party, but sweet stuff here :)
Hey mitch, I noticed you took the HD radio cables off your site, but I ordered a cable on Friday.. is mine still coming through? No rush... just excited to finally have radio again. :)
i will fix site... im home on friday for a few hours, then off to disney world
(im stuck now in a hotel with deathly slow internet, in dallas tx)
i will assemble, and ship what ever is paid for by the time i get home
i will fix the site to take some more orders :)
ill try to catch up on any questions too
again thanks for the overwhelming support, im glad to provide the solution for radio in the car for yas!
