Scott, Yes, I think I did mention the issue with KGO when it happened. Now with IBOC hash, KEX's hash is an issue during the day on 1180 and 1200 but near LSS, KOFI 1180 and CJRJ 1200 get strong enough to totally over power the hash without phasing. So where there are strong signals, that will pro

[IRCA] DRM vs IBOC

I have also heard that DRM is much better than IBOC, but the possible profits to be made with higher fees are better with IBOC. DRM also does not cause as much QRM as IBOC does. Plus the audio quality with DRM is better. Anyone ever compare the two? 73, Patrick Patrick Martin KAVT Reception Mana
