Hmm.. I thought it was around 15 minutes into my recording (which started around 12:51am PST, which would have made it around 1:06am, besides the possibility that the clock in my Zoom H2n could be a minute off). I can't seem to pick anything out of the recording, though. I even listened to most of it again in case I had the wrong time in my mind, but no dice.
If it's tough to get KDWN to shut down, would it be possible to reduce their radiation to the southwest by about 140-160 dB during KOTZ's test? ;) Another thing I was thinking .. don't know if this would work, but .... might it be possible to include some fully-modulated morse code at, say, 7 kHz, along with a fully-modulated continuous tone at 6 kHz? (BTW by fully modulated (it's possible I have the wrong term) I mean the same power goes into that morse or into that continuous tone as is in the on-assigned-frequency carrier.) I was thinking I might have a chance, if the continuous tone could "fool" my PL-606 into thinking there was a carrier there, and the morse would beat with it so I'd hear 1 kHz morse by tuning to, in the previous example, 714 or 726 kHz (getting away from some of KDWN's splatter, also XEEBC/XEX (not sure which, suspect the former) on 730 and KSPN on 710 are usually much weaker signals than KDWN, but KCBS's IBOC could be a problem, though). (Maybe an offset of 5, 6, 7 or 8 kHz would work for the continuous tone, with the morse being somewhere within that range and within about 1.5 kHz of the continuous "carrier".) (It probably wouldn't be possible to switch KOTZ into a mode where their main 720 kHz carrier was shut off and instead they were on 714 or 726 kHz, though.) I did get KBOI, though. Posting a recording will have to wait till at least Wednesday, though, as I have other non-radio things going on the next few days. As for KDWN, this video clip could give you a little idea of what KOTZ needs to punch through. ;) http://www.youtube.com/watch?v=PaLPsevaRGk And just 40 kHz up from that: http://www.youtube.com/watch?v=ICaOz_Nvxeo ________________________________ From: "Paul B.

And as for KDWN shutting off, its not that easy to get a 50KW major market signal to just shut down.

I think I heard a hint of phone off-hook signal once through heavy KDWN QRM in SoCal, but I'd have to check my recording (which may not happen till Wednesday). Also it would help if somehow some downtime could be arranged at KDWN so those of us in Southern California would have a better chance at logging KOTZ. > > > > >________________________________ > From: Russ Edmunds <[email protected]> >To: [email protected] >Cc: IRCA List <[email protected]> >Sent: Saturday, March 10, 2012 5:35 PM >Subject: Re: [IRCA] [NRC-AM] Good News Regarding The KOTZ 720 DX Test > > >It'll take a week at least for the current activity to quiet down.
