About an S5 / SIO 333 here at 2324.

[Skipmuck]

Just a weak carrier here at 2325 UTC....no audio noted
2341 UTC Just had a brief fade up of music! First audio detected so far 
2343 UTC "What Do You Want From Life"-The Tubes (About 2 minutes of audio peaking at S5!)
2349 UTC OM talking now...mention of 30 minutes, into a singing Miller High Life commercial!
2350 UTC Signal just jumped up to S7...power increase or prop? "Dust My Broom"-Elmore James
2353 UTC "Money Trouble and Love"-Hank Thompson
(Signal faded deep into the noise at 2356 UTC...still have a weak carrier)

2328 The Doors. / five to one     long fades S3

Hearing some music coming in but most of the time it is in the mud at 00:38UTC! Very poor will see if it improves!

[Traveling Wave]

0102 UTC - Music playing but signal is down in the noise.

[ChrisSmolinski]

A very nice SIO 444 signal at 0945 UTC, break in the carrier around 0953, then back on with an open carrier.

good morning to you Chris and all the respected HFU members.
i did some work on the TX and amplifier early this morning.
added a secondary 7Mhz LPF in series with the first 7Mhz LPF on the IF pre-amp output to further attenuate the second harmonic.
reworked pin 5 of IC SN169136P low level balanced modulator/RF mixer.
the amp grid current and plate current was also re-adjusted (now at 1KW RMS with 700mA plate and 250mA grid)
the amp input pi-tank was also re-adjusted for minimum VSWR at 1.2.
with this simple IC, anyone can generate full spectrum audio AM low level modulation.
simply input an RF input signal to pin 2 - audio input to pin 5 with DC bias to control carrier level with pull down resistor and DC coupling capacitor - AM RF out on pin 1.
if the DC bias is "zeroed" (balanced), you get DSB.

1220z June 5th Hearing you S9 20 + on a mid-Atlantic SDR. Sounding very nice.

[ChrisSmolinski]

After dropping out, the signal has come back up. S9+10 according to the (probably not accurate) NRD 545 S meter, but it sounds great. I have the bandiwdth opened to +/-6 k kHz and am feeding the audio to the Fender amp.

[TheRelayStation]

thanks guys !
but its going to be the "temporary" band conditions as i predict sometime between 1400Z - 1600Z, the conditions wont be favorable any longer - im at the usual 50W (10Khz audio).
i was quite surprised to see the sweep go to 20Khz on the spectrum and see 20Hz very prominent as well - looks like the re-work i did on the TX worked out very well.
y'all have yourselves an excellent day today, ill be playing fascinating wonderful oldies for the better part of the day while i stability test everything
edit 1:
back down to 1 watt for 24/7 operation for the remainder of the week.
