Over the years I have pondered this as well, but have no hard data.
As is well known, I have a Procaster mounted on a third floor window frame of a 100+ year old wooden house. It is mounted to a plastic conduit pipe that is then mounted with standoff brackets to the wooden window frame. There is no ground lead attached at all.
The only wires c…[Read more]
Here we go with Oompah Hour #273.
It’s an exciting show, as there’s been drastic remodeling and organizing going on in the studio. This has led to giving me access to hundreds of records that were stored in places that made it very difficult to get to them, so they haven’t been played for a couple years, at least, if ever. So lots of fresh so…[Read more]
A lot. LOL. Hard to say exactly. But for the fun of it I tried to ballpark the “organized” records by counting how many records fit in 6 in inches of shelf space then adding up linear inches of shelved records and doing the math. This leads me to about:
1450 – 45’s
550 – LP’s
And no idea on the 78’s, as they’re sort of stacked up here and…[Read more]
There’s nothing to apologize for, AMRadioLegend. We all appreciate updates on this highly anticipated device.
Rich, the issue of the legality of the Talking House & Range Extender has been dealt with extensively here in the past.
From the website of the manufacturer:
“When I connect my Talking House Transmitter to a Range Extender (Antenna…[Read more]
Rich, the Talking House plus coax and ATU as an entire configuration was certified under Part 15.219 by the FCC. That means that it complies with those rules, as long as it is installed as supplied with no modifications made (including attaching a long ground lead). I’m struggling as to why you posted those calculations (someone might infer t…[Read more]
Ok Rich, the model with the ATU is irrelevant. Let’s assume the ATU is fed vertically with 25 feet of coax. Only a twit would place the transmitter at the base exposing it to weather. Your modeling does not show a fence mounted (3 feet) ATU with much of the coax horizontal or laying on the ground. As I said, you have no idea how I or anyone e…[Read more]
Amateur radio communication at the mw level is almost always narrow band type modes, such as CW. Beacons are essentially a narrow, CW pulse. It’s very difficult to communicate with SSB at those power levels, never mind AM, which requires a much greater bandwidth.
Mind you, it might be worthwhile attempting to use SSB on 13.56, just to see the k…[Read more]
Here we go with another hour of perfectly good polka and old time music! Show #272 is waiting for you at the usual link:
Felt like and extra-fun show to me! Enjoy!

Small towns are disappearing as well, so it’s not surprising that their radio stations are going.
I don’t like it, and don’t agree with it, but it just may be the natural order of things as we get more and more connected in other ways.
It doesn’t mean that we (Part 15 broadcasters) have to give up and/or stop.
Those corporate radio stations…[Read more]
There have been a few people in the past who have used the ISM frequency at 13.56 and have posted about it. If I recall correctly, range was similar to Part 15 AM stations that they had run, but that’s all I can remember (1/2 to 1 mile).
It’s important to note that on the ISM frequency you’re not limited by output power, but by field strength -…[Read more]
Part 15.219 doesn’t limit field strength.
The Talking House transmitter, combined with the ATU (and coax) has been FCC certified, and so if you use it as supplied, without adding a long ground lead to the ATU, the field strength (or the fact that the coax may radiate) doesn’t matter.
