European MW Pirate Radio / Charity Radio
« on: October 23, 2019, 2043 UTC »
Not a logging but Charity Radio from Ireland can just be heard here on a UK SDR on 927 Khz. http://g0ezy-kiwisdr.ddns.net:8073/ On for a short time only.
Shortwave Pirate Radio In North America And Around The World, And Other Signals That Go Bump In The Night
We seek to understand and document all radio transmissions, legal and otherwise, as part of the radio listening hobby. We do not encourage any radio operations contrary to regulations.
Always consult with the appropriate authorities if you have questions concerning what is permissible in your locale.
I found the band plan but it doesn't mention anything about a non-interference basis.
That's the one I ordered.
There's a top and bottom "cover" but the sides are open. It's not a big deal.
To take the stress off the SMA connectors, I've mounted it in a very small flight case with 2 "N" type sockets mounted on the side of the case. All connections will be made via the "N"s now.
There's a bigger version available now. Larger screen and I think it goes to 1.2 Ghz. About 3x the cost though.
And no reason why not.
The purpose of the ground radials is to act like like a mirror of the radiating element which is the vertical section and is why concentrating the radials there is best.
In my own present setup, I can't run a radial the full length of the horizontal anyway as it runs over a neighbours field. I do have about 30 unused radials at the end of the horizontal wire from a previous setup which I may connect to the current setup. The more the better!
I'm lucky that I have a proper Field Intensity Meter (Nems Clarke WX-2E, similar to a Potomac) so any changes I make can be accurately measured.

« on: September 20, 2019, 1941 UTC »The link to the Monitoring Times (in the bottom of the Wikipedia page)Can you link to the specific section please.
gives a much better answer to that question.
Saying that 5730-5900 can be used by broadcasting on a non-interference basis,
and many other details.

Only a hint of a signal. Just getting a little audio. Improving.

As far as I know it's 5900 although there are a number of legal stations below that.
The entire HF spectrum has legal stations broadcasting outside of the "official" bands.

General Radio Discussion / Re: Pirate DAB multiplexes take to the air in Dublin and Cork
« on: September 19, 2019, 1152 UTC »
At the speed Frank is rolling out "FreeDAB" (currently also testing in Dundalk and rumour that Sligo is next), it won't be long before he has greater coverage than the legal DAB operated by RTE. And with a greater range of stations.
There has being independent DAB in Ireland on trial basis. DB (Digital Broadcasting) in Dublin, Total Broadcast in the South East and most recently EireDAB in Cork and a test setup from RTE's studios in Dublin. All off air now.
Whilst I'm not sure that the publicity he is getting is going to be good for him, it might spur the BAI to consider licencing independent ops and stop giving in to the whims of the FM stations.

New frequency?
I'm hearing a signal on 5804. Nothing on 5824 here.

I received mine last Monday, just short of a month since ordering.
First impressions are good.
Checked it on an FM dipole which I believe is tuned to 91.6 Mhz. It returned a min reflected power on 91.4 but I will forgive it as the aerial is only about 8 feet up and the coax is dangling under it so may be throwing if off a bit. It may not have been calibrated to the band when I checked it also.
On one of my HF, aerials, it gave me a reading of 1:1 just off my operating frequency. The aerial is good for +/- 200 Khz (about 1.5:1 at the extremes) so happy with that. Z= 48.5 Ohm Zs.
Measured a new inverted MW antenna I just put up. Lovely curve on 1430 Khz. Z=40 Ohms without the atu so matching it should be easy enough.
I've measured several filters I have here, both homemade and factory built with interesting results. I think this could be an invaluable tool for building filters.
The build quality is OK. Pity it's not a in an enclosure.
Spent most of the morning I got it making up SMA patch cables.

General Radio Discussion / Re: FCC petitioned to open up 45 to 50 MHz for DRM+ broadcasts in the USA
« on: August 30, 2019, 1239 UTC »
I think DRM has missed the boat. Pity as I think it had potential but the receivers were poor and too expensive.
About 16 years ago, I converted my MW transmitter for DRM using DReaM software with some success but nobody could hear it except me, and only with a doctored radio and a PC.

« on: August 30, 2019, 1231 UTC »Some run a wire along the ground under the h portion of the L for its entire length, in addition to the radials at the v portion.
This is exactly what I do, with good signal reports.
And no reason why not.
