Even with 100% sine wave modulation it consumes 'only' about 87 kW from the AC
line. Power consumption during normal programming is less than that.


Indeed ... hence the not insignificant popularity of the DX-50 or 3DX-50.

IMO, the Nautel sounds better.

Mine too. Had the opportunity to choose a few years ago for a new AM, and
went with a Nautel 100 kw with a 30 kw aux. Defintely a better sound.

I've noticed that the CDBS now often has separate day and night listings,
even where the parameters are the same. See the applications for WYCB and
WOL for example. They are both Class C stations.

Also what is the "2" in ND2 all about, I can't see
any difference day and night?


It is common, now, to file for ND2 or DA-2 even though the desired mode is
actually ND1 or DA-1.

That way, if one mode proofs OK, yet the other mode doesn't, there are more
options available.

In theory, one could refile for ND1 or DA-1, but that's another Form 301,
another big check to the consultant and another big check to the communications
attorney, and ... in short ... a waste of money.

In the days before dial-a-power, ND2 made some sense for the case where a
station could, say, make 1 kW work days, but just missed 1 kW nights, and it
didn't want to refile for 1 kW-D, 0.5 kW-N.

So ... 1 kW-D and no resistor, and 1 kW-N with a resistor, simulating a less
efficient radiator, was a possibility.

Today ... 1 kW-D and 0.82 kW-N might be one possible example, for a station
with 225 degree stick, which is required to radiate no more than the Class B
minimum efficiency with 1 kW at night.

I think San Diego's ex-KDB (or was it ex-KGB ... both are historic calls in
SoCal) is operated similarly to this.

Only for its auxiliary stick, not its main stick.

It's main remains 50 kW, as ALL U.S. Class As must operate, unless
grandfathered (Bakersfield's 1560 only) or a former Class I-N (Alaska only).

ND-2 = non-directional, different "notified" efficiencies day and night.

660 and 880 can also be diplexed into the auxiliary, as they are already
diplexed into the main.

So, these operations are theoretically possible:

1) 660 and 880, each with 50 kW, into the main,

2) 660 with 50 kW into the main and 880 with reduced power into the auxiliary,

3) 660 with reduced power into the auxiliary and 880 with 50 kW into the main,
and

4) 660 and 880, each with their respective reduced powers, into the auxiliary.

Anyway...anybody know why WFAN...with a great signal, best in New York, low
frequency 660 kHz, 50 KW ND, island tower site (multi with WCBS) with
salt-water path to surrounding land...would want to drop to 35 kHz.

I spent 20 years in New York and recall the WFAN signal was one of the
worst. I was in the West Village by the river and could barely receive
it. I couldn't receive it in my office at WOR in Times Square.

I get it better in New England than in NYC.
