[IRCA] Curious To See How Everett WA Am Stations Perform In Digital-Only Test

["Rick Lewis" <ricklew@xxxxxxxxxxxxxx>]

First of all, two stations, co-owned KRKO-1380 in Everett WA, and KKXA-1520
in the same county, will be testing in all-digital mode for several periods
between now and Tuesday morning.

Both stations will test for one seven-hour period during the day and two
four-hour periods during the night.

The first test will be on KKXA-1520 Thursday night from 9 PM to 1 AM. 

No test will begin on Friday.

The second test will be on KRKO-1380 on Saturday from 9:30 AM to 4:30 PM.

The following two tests wil be on KKXA-1520:

Saturday 9 PM-1 AM and Sunday 9:30 AM-4:30 PM.

And the final two will be nighttime tests on KRKO-1380: 

Sunday and Monday nights from 9 PM to 1 AM.

 

I have no doubt that the daytime tests for both stations will please station
owners and the IBOC proponents.

Both stations are currently well-received in Seattle via IBOC in the
daytime, with 50,000-watt signals coming from an adjacent county.

The night signals may be trickier.

Even though 1380 has other occupants, it may decode at night. It has a
better signal with less fading and interference.

KKXA-1520 has strong interference at night from a station in Lake Oswego,
Oregon near Portland.

I believe some areas of northern California get KKXA better than we do in
Seattle, but the interference from the pre-existing Oregon station is
formidable.

I'll be very surprised if KKXA consistently locks in Seattle at night, but
that's what tests are for.

The meaningful real-world test would be for all-digital on KKXA and the
Oregon station. 

Anyway, it _will_ be fascinating.

This is no WBT situation at night! I haven't received either station via
IBOC at night, although both are received well on day pattern. 

I hope to be recording at least some of each test in HD mode, using nothing
fancy--a Sony XDR S3HD radio with its supplied AM loop.
