Title: Marion's Attic WBCQ 7490AM 5/1/16 2100z

Excellent reception.
This is a gem of a show, a mainstay of WBCQ for many, many years.  Treat yourself if you have never listened.

WBCQ's TX definitely needs dire maintenance.
splattering up to 20Khz from the ITU operation specification of 5Khz AM for their TX.
is this indicative of a degraded audio modulator valve/tube or just simple over-driven modulation ?
(not to mention interference from another foreign SWBC station at 7495 Khz)

You are right.  I have been picking them up on odd frequencies lately - forgot exact frequencies but one in the 6000's and one in 8000's, I was thinking some sort of harmonics.  You might want to send that shot to WBCQ.  Nonetheless, listening to the program on a 1936 Emerson AR-176 is a wonderful way to end the weekend.  I'm not hearing anything on 7495.

ive spoken to Allan a few times.
he is either lazy, stubborn or doesnt have the funds, nothing has really changed.
at least the TX is closer to frequency this time instead of the usual -100Hz from center, its only -15Hz this time, not that it really matters but most SWBC stations follow ITU specs, Allan isnt one of them  :P

2150z WBCQ signal completely dropped. I tuned to 7495, heard foreign broadcast - I'm thinking something from Algeria.  WBCQ returned at 2154z.
