[IRCA] WNTP Test

["R. F. Tetro" <rtetro@xxxxxxxxx>]

Good evening, all.

I wanted to let give a heads up to those of you who were unable to 
receive the WNTP DX Test back in December that you have another 
opportunity this Friday night to log the station.

Between 12AM and 2AM, Friday night-Saturday morning, on March 5, I have 
to conduct an audio proof on WNTP because of some changes I've made to 
the transmitter system. 

This WILL NOT be a DX Test, so you won't be hearing a lot of tone 
sweeps, warbles, morse IDs, etc.  What you will hear is a lot of 
consistent 50HZ through 10KHZ tones, some voice ID's, and dead air, 
while I measure frequency response, noise, and THD and IM distortion of 
the main transmitter at full power on day antenna system.  This means 
that during the test I will be operating at 50KW on day pattern.  If 
time permits, I will also repeat the tests on our standard 10KW night 
pattern.

As always, I will QSL any reception reports I get.  Speaking of which, I 
finally sent out the remaining WFIL and WNTP QSLs this afternoon from 
our last tests.  Thanks for your patience.  Sorry it's taken so long to 
get them out, but we've been under a lot of pressure with some major 
projects in the past month.  If you don't receive yours within the next 
week please let me know.

Also, because of the intensive nature of the work I need to do Friday 
night, I will probably be less available during the tests on the NRC and 
IRCA lists, and the #MWDX channel, than I have in the past, although I 
will try to check in from time to time.

Once again, this coming Friday night is NOT a DX test, but an equipment 
performance test, so you will lack some of the advantages that a DX Test 
provides.  But hopefully you will be able to pick up the test tones, 
especially those in the 2KHZ-4KHZ range, which tend to pierce through 
the noise.  Tones will be transmitted at four modulation levels:  95%, 
75%, 50%, and 25%.  Hopefully the DX conditions will be less auroral 
than they were in the December test.

73,
Rene'
