Hey Tim, thanks for the update.

I’ll get the link onto The ALPB Oompah Hour page right away as well as Oompah Hour 312.

A link to every Oompah Hour is found at http://thealpb.us/OompahHour.html.

What?  No new Oompah Hour this week?

I’m sure it will be along shortly.  After 310 episodes Tim’s allowed to be late with 1.

We certainly appreciate Tim putting this show together every week.

I had the pleasure of meeting Bill when he dropped in the check-out our TIS station supplied by ISS.

Bill got out his Potomac meter and we ran a field strength test to see how the system was performing.

A very nice gentleman.

Our station has about the same coverage as described above and has been on air for about 15 years.

Correct, EAS on Part 15 is not a requirement.

But some strive for something more than what is currently permitted.  And the hope is that a new low power community broadcast service will be created by meeting specific requirements such as EAS.

Some feel it’s better to aim high and miss than to aim low and hit…

The Kenwood is playing out the Bluetooth audio which is your program audio.

At the same time, the Kenwood’s radio receiver is monitoring a local radio station but not playing it out.

When an EAS alert is received by the Kenwood radio receiver, the Bluetooth audio is muted and then the local radio station audio would play out.

When the EAS alert…[Read more]

If you use an audio compressor/limiter that has “sidechain” input control, you wouldn’t need a VOX switch.

The sidechain control of the program audio would drop the program audio low enough for the Alert to play over it.

This could be an even cheaper solution if you already have the sidechain capability.

Then again, a vox switch on the audio out from an inexpensive Alert radio could activate a switch also.

That could be an inexpensive EAS system.

There are EAS systems for much less although still pricey.

Our LPFM used an EAS by Dasdec.  Cost was around $3k.  Has 3 internal receivers with room for 4.  Has both analog and AES audio capability.  Logs all EAS events including CAP.  Stores audio clips of events and fully programmable for type of event to forward.

Perhaps a digital ghuru coul…[Read more]

So if I understand this correctly, my program audio is sent via Bluetooth to the Kenwood receiver.

The audio from the Kenwood is sent to my transmitter.

The Kenwood Bluetooth audio is the selected output but the Kenwood receiver is tuned to a local radio station.

When the local radio station puts out an EAS alert, the local radio station EAS…[Read more]

P.S.

Regarding The ALPB forum, the forum developed into it’s own entity.

When The ALPB group experienced a “blow out” shortly after Jim passed, things went down hill quickly.

There was little support for the original concept of The ALPB.  Rather it had morphed into the forum with its own dynamics.

As the originator of The ALPB, and with no…[Read more]

Hi Tim,

As for The ALPB, the problem is that Chairman Jim Henry passed away.  I had transferred the domain ownership to Jim just a few months before he passed.  That left the domain ownership in limbo.

I contacted GoDaddy (domain registrar) and explained the situation and that I was the previous owner.  They would not simply transfer the do…[Read more]

The records you cut, are they straight to vinyl or are those acetate on metal?

I have a 45 of a band my brother was in back in the ’60s.  It was cut on an acetate on aluminum.

Hmmm.  I used to wash records as he shows but I never would have thought about using WD-40 on vinyl.
