WCCM 1570 is a simulcast of WJDA?
- Thread starter MarcB
- Start date
No, WJDA was either off‐air or w/dc. This morning—at least in the 9am hr.—they were on with a dc.
As for WCCM, the 9am TOH ID was for WCCM/W287CW—no mention of WJDA.
Given the weather conditions, it was probably just some feed screw‐up.
Probably..yesterday I tried both streams at least and they had different programming.
What's "w/dc"? "w/DigiCipher"?
I had the impression the original poster was listening over-the-air, not via streaming. Did I miss this?
Don't know if he was listening on air or via stream but this contour map says by day (he mentions 3 PM at one point) fringe signal does touch a part of CT and you never know, with groundwave you may be amazed what you get.

He said he was "picking up" the station, which isn't a phrase you'd normally use for clicking on an internet stream.
My guess is that he meant with a "dead carrier".
Transmitter on, but no programming/modulation.
Oooh, I overlooked an obvious one; thanks, Eli!
Yup—I figured it was obvious for us radio geeks! P=)
Likewise, “xmtr” = “transmitter” and “prgmg” = “programming”.

I don't know if this designation is still used, but at one time, the International Telecommunications Union (ITU) referred to emissions of an un-modulated RF carrier as "A0".
Now how 1300 WJDA's A0 emission could be received on 1570 in CT - well beyond the primary service area of either station - remains a mystery to me. I don't believe these stations are co-owned nor did I get the impression the "listener" was streaming, since he "picked up" the signal (presumably over-the-air).
And, again per the ITU: A3 designates double sideband amplitude modulation of one channel containing analog information.
1570 is a semi-regular pickup in the late afternoon for me.
In the past I have gotten WFED 1500 (the former WTOP) Washington DC up here as early as 2PM in December. I don't check for it anymore because WFED is not as interesting as WTOP is.
Both WCCM and WFED were on my Walkman.
One of most amazing pick ups for me was 250 Watt WJIB 740 on a Car Radio (it was a while ago so I don't remember which car). WNYH (the former WGSM) from Huntington, Long Island was off the air at the time.
Another amazing pick up on a Car Radio was on the stock radio in a 1995 Pontiac Sunfire. About 8 years ago I picked up WGHM 900 Nashua, New Hampshire around 1PM sitting in the driveway of a buddy's house. WGHM is 910 watts and there is a local station on 910-AM.

There were two separate issues here: WJDA being either off‐air or with dc/A0, and WCCM relaying WJDA.
As for the latter, I know Christmas morning—remember, it was stormy—besides WEZE and WJDA being off‐air, WESX also appeared to be off for a few minutes, then came back on (possibly with reduced power) with brokered programming(?), ID‐ing a few times as 5-40 WLIE, then abruptly cut away to dead‐air for a couple of seconds, after which they ID‐ed as WESX, then went to other prgmg.
Now, were they mis‐relaying WLIEʼs actual, live air feed, or was it just lousy editing of a pre‑recorded program that previously aired live on WLIE?
This may have been the same type of situation with WJDA via WCCM.

Ah, now I'm getting it. I seem to recall back in the days just a few short years ago when WRKO was getting even less love than it was getting during its last days with Entercom, that it was picking up The Financial Exchange off-air from 1120 WBNW, and the latter's ID was heard on 680. I knew what was going on - 'RKO was on automation and no one at Entercom was monitoring - but it could've confused a listener not familiar with the programming arrangement.
Thanks for pointing that out!
Unrelated: WCCM's tranmitter in Andover puts out 30-KW non-directional. As the crow flies, I'm probably within two miles of their transmitter. They splatter considerably, and, on one of my cheaper AM radios, they cause background chatter to 680 WRKO as follows: the image frequency for WRKO is 1590 KHz (680 KHz + 2 * 455 KHz = 1590 KHz). The splatter from 1570 that goes out to 1590 can be heard in the background of my WRKO reception. Again, this only occurs on a cheaper AM receiver. This is not a problem at night when 'CCM's power is reduced considerably, nor did I have the problem before 1570 was moved to Andover. For a while I blamed 'RKO's AoIP links, but came to realize that was not the case.
For the uninitiated:
- AoIP = audio over Internet protocol.
- image frequency: almost all AM super-heterodyne receivers have an intermediate frequency (IF) of 455 KHz. The AM receiver's local oscillator must be tuned to 680 KHz + 455 KHz = 1135 KHz to receive WRKO at 680 KHz. However, if a signal at 1590 KHz mixes in the receiver with 1135 KHz, the output is also at 455 KHz. A "good" AM receiver usually contains some preselection so that this is a highly unlikely occurrence, but, then again, it was at one time probably not expected that a high-power signal like 1570's be located where it now is.
Oh you would be surprised. The stock radio in my Mom's 2010 Honda Civic is great. I have gotten WSPR 1490 West Springfield (the former WACM) down here on a few occasions. They are 470 watts.
In fact, I used that to pull a prank on my Mom. During the summer of 2015 1490 West Springfield and its then simulcast partner 990 in Southington flipped to Oldies. 990 became a new favorite station of hers (mine too actually). While my Mom was in the bank I stayed in the car and found out I could pick up 1490 albeit weak and full of static. I then turned the radio off. Then she stayed in the car while I went to the grocery store. I came out a few minutes later and Mom had switched to an FM station. When we get to our next stop I say to mom "How come you're not listening to Oldies 990 any more?" She said "They're having problems. It's very very staticy." Then I showed her that the radio was actually on 1490. She didn't even notice even though the display on the radio said 1490. I then put the radio back on 990 and showed her the difference. - She called me a brat for doing that to her.
WJDA, WESX, and WLIE all have common ownership. If they use an internet feed to pick up programming they could've potted up the wrong internet feed or it's possible they run the same program. Note: I said program, not simulcast.
