Permit granted for new AM station

Rowe, New Mexico: 1420KHz:
Permit granted for new station.
2,500 watts daytime
103 watts nighttime
non-directional all hours
35-29-51N/105-40-20W, about 25 miles southeast of Santa Fe.

This station must propose a rather unusual antenna system...

The FCC requires new AM stations to have a minimum nighttime power of 250 watts, or a minimum nighttime signal of 141mV/m at 1km from the antenna. This station obviously proposes a lot less than 250 watts, but a signal of 441mV/m. How they are able to do this with a non-directional antenna I have no idea.

FCC broadcast station totals

The FCC has released a count of authorized broadcast stations as of the end of March:

AM: 4,778 stations (down 4 from the end of 2010)
FM: 6,533 stations (up 7)

non-commercial FM: 3,417 stations (up 106, as the Commission continues to act on a a PILE of applications from a recent filing window. They're not done yet, expect another significant increase next quarter.)

UHF commercial TV: 1,022 stations (no change)
VHF commercial TV: 360 stations (down 8, probably due to deletion of already-defunct stations in the rural West.)
non-commercial UHF: 285 stations (up 1)
non-commercial VHF: 107 stations (no change)

FM translators: 6,141 stations (up 10, they're still working on a filing window for these too.)

UHF TV translators: 3,043 stations (down 30. They've been canceling defunct translators & LPTVs lately.)
VHF TV translators: 1,411 stations (down 43)
UHF LPTV: 1,656 stations (down 11)
VHF LPTV: 516 stations (down 8)

Montreal 690/940 to return

A message on quotes a local TV report as stating two new AM stations will launch in Montreal later this year. The former all-news, and before that, CBC, frequencies 690 & 940 will be used. Both frequencies will carry continuous traffic reports.

Looking in the Industry Canada database, both licences were canceled on February 22nd of last year, after their previous owners took the stations silent.

Last Tuesday, May 10th, new technical proposals were filed for use of the 690/940 frequencies.

940 would operate in English, from 45-38-58N/73-42-51W.
690 would operate in French, from 45-30-00N/73-35-58W.

Yes, it's ironic that two different sites are proposed. Neither proposed site is the same as that previously used by the stations, and neither site is the same as any other current or recently-defunct station. No power or antenna pattern is given for either frequency.

(I suspect the 690 site coordinates are a typo. It turns out those coordinates are in Mont Royal Park -- a very suitable location for an FM station (and where most Montreal FMs are) but not so much so for AM, especially at high power.)

On April 14th, another proposal was filed, for use of 1530KHz at the same site as this month's 690 proposal. Again, no power was given, nor is there any indication of who proposed 1530. (whether it was the same group responsible for the 690/940 proposal)

I haven't seen anything clear the Canadian Radio-television and Communications Commission yet. I would expect they will need to sign off on this.

These stations were of course widely DXable in both their previous incarnations. The other side of the coin... is that if you're east of the Rockies, you need to clean up on 690KHz now, while the big Montreal signal is still silent. Real plums like Vancouver and the low-powered station in western Nebraska may be ripe for the picking.

AM stations deleted

The following AM stations have been deleted:

KCLA-1400 & KOTN-1490 Pine Bluff, Arkansas
WDSK-1410 Cleveland, Mississippi
KZEY-690 Tyler, Texas

All four stations were deleted for remaining off the air for over a year. Three of them are co-owned. Seven FM stations, most if not all co-owned with the three AMs, were also deleted for the same reason.
