Cedarville Univ to sell WCDR-FM and Network of stations (88.3 in Columbus)

This is the email I received today on the status of these stations. It looks like 88.3 and 90.1 will be back on next week??

I say we'll see 88.3 and 90.1 on within a week or two (baring any last minute issues) EMF has a team of engineers going from site to site to bring them online with the programming. (3 Full Power FMs, and near a dozen translators to switch over is a lot of work) exp since a lot of the former CDR stations are in very rural areas :)

btw ;) this is just a random fact.. WOHC 90.1 leases tower space at the same site as WZCP (89.3 CHILLICOTHE) which runs a automated/voicetracked version of the CCM "The River" format from WCVO Columbus.

W202CC/Columbus returned to the air earlier this evening as AIR 1...

Yes and its fun to listen to on the west side.. There is a SLIGHT delay between W202CC and WOAR ... so when the two signals mix it seems very 'trippy' to listen to!. Processing on W202CC seems very flat too for a CHR..

90.1 WOHC isn't on yet .. My guess they will return to air tomorrow likely.
 
Interesting you mention 90.1 WOHC. Checked the FCC site a few hours ago and they have not filed for a Silent Notification. So, they probably plan on getting WOHC on the air air sometime tomorrow.
 
My guess on the two signals (88.3 WOAR) and 88.3 W202CC having the delay is due to both transmitting and processing.. according to the Purchase agreement for WCDR, 88.3 W202CC used a David III audio processor for its processing...

I wonder what WOAR uses? Naturally having a different air chain would make having a slight delay between the two signals on the same frequency airing the same programming even more likely.. It's for sure not listenable on the western ends of Franklin County (I had been getting a stereo signal on 88.3 in my car from WOAR prior to W202CC coming back on)
 
W202CC is Wegner => David III => Crown100, for some reason only running at 80-90% modulation.

The Inovonics introduces no delay. EMF is mostly an Omnia shop I believe. WOAR isn't HD, and analog Omnia presets don't normally add delay. Could just be a difference in timing between the two downlink sites? Haven't been to that side of town yet to hear it for myself, but WOAR does put in just enough of a signal to be a problem there for sure.

I wonder if they plan to make good on Cedarville's CP to move to 90.1 in Columbus?

It must be the delay in downlink timing... Naturally both sites are using the ipump however satellite is satellite and the ipump still got to decode the data stream.. Sicne naturally its a digital carrier (satellite - compressed audio ) .. it's possible that the uptime on the one unit has been long enough that its buffer has a slight delay? (I am no engineer but know enough to understand technology) :) but when I get towards Hilliard there is for sure a mix between W202CC and WOAR and you notice the processing differences and the delay (was listening on the drive back to work and could hear the DJ say "air1 then slightly later you would hear "air1" again ..)

Will they move to 90.1? not sure..

My guess Cedarville's app for 90.1 was to try and get away from AFR's 88.1 WWGV .. and from the pending CP for 88.3 in Johnstown (if OHIO EAST-WEST CULTURAL BRIDGE ever builds their 6kw B1 CP they have they will rimshot the NE Corner of Franklin County based on not necessarly real world coverage maps) ..

Speaking of 90.1... WOHC has a CP to go from 2kw V to 7kw HV on the same tower in Chillicothe which means their signal will become even clearer in Columbus (When CDR was on .. i could most days get 90.1 WOHC in my car better than W202CC) which means even if W202CC moved to 90.1 it would have to contend with WOHC on the south end.. though maybe for W202CC that would not be that big a deal as W202CC beams most of it's signal towards the north (If I remember right).. (and their CP for 90.1 is pretty much the same pattern except a frequency change)

Guess time will tell..

Any digital processor will have slight delay...so I'd wager that the processing delay on a David-III is going to be different than whatever model Omnia is in use at WOAR, and that's probably what you are hearing.

In the case of the LPFM I take care of, the delay over the digital STL is more noticeable than the Omnia-3FM Turbo we use. I had to turn up the interleave depth on the Starlink to help avoid dropouts and it introduces enough to make off-air monitoring difficult.

The typical EMF "zombie station" site has the sat dish right next to the shelter, so that takes STL's out of the equation. I'm not that familiar with sat equipment so I don't know what the latency is for the Wegener receivers, if it's variable, or if it's different by model.
 
The "doublespeak" delay I noticed this morning on the west side was probably on the order of 150-200ms or so. Def-definitely en-enough to-to be-be an-annoying to-to list-listeners on that side of town lol. Perhaps EMF could employ some kind of intentional synchronization at W202CC, similar to what on-channel booster stations use?

Cedarville's waivered CP to move to 90.1 was indeed to escape Ohio East West Cultural Bridge's granted CP for 88.3 in Johnstown. OEWCB has until May and EMF has until next October to build out their respective CPs (if they're really going to?). Might be interesting to see if W202CC's move to 90.1 would ultimately enable them to return to an omnidirectional pattern, which they cannot do at 88.3 due to WWGV. Even with just 10W, when Cedarville was omnidirectional at 88.1, they covered pretty much all of Franklin County with a listenable signal (in cars, anyway). The potential for conflict with WOHC's upgrade does exist, but as the owner of both, they can decide which compromises to make.

That much is too much for processor delay variance...even the longest Omnia or Optimod delays are on the order of tens of milliseconds. Must be in the satellite downlinks.

I would synchronize those if at all possible.
 
The satellite receiver (iPump 6420) that EMF uses for KLove/Air has the following manf. specs:

QPSK DVB-S Carrier

with a choice of:
Format Support mono/stereo 16bit PCM5
MPEG-1 Layer 2, mp2, (mp3 option)
Sample Rates 32, 44.1 and 48kHz

I am guessing that EMF is using one of the "compressed" formats for KLove/Air1 (I am going to go on a wim without knowing for sure but maybe even the mp3 option the Wegener has) .. which could cause the differences in decoding between the two FM sites. I know usually with mp2 (commonly used) the delay should be fairly low level.

Another thing (kinda off topic) I am surprised that since the iPump's have the ability to play local files that they don't ID their translators via that function... (the translators all audio wise ID for Air1 as "KHRI Hollister" - what is being fed down the pipe from Rocklin) back prior to Cedarville wanting to 'sell' their stations they would ID 88.3 locally each hour with a cut in right at the TOH. (towards the end of CDR's network life when they re-branded from The Path to 90.3 WCDR they started to ID the translators only during the required window to ID them -- made for a long legal ID usually at 8am and 4pm that would list all their frequencies and call letters)
