When he did hear 3LO on the crystal set on one occasion, he had all his neighbours visit over to his place to witness the event.

Came across this video by accident Similar experience where I live, tho now in 2024 portable reception is much better on DAB and has been for a while. A couple of little things… I can’t remember for sure, but aren’t some FM transmissions vertical only….meaning you need a vertical aerial. Other FM transmissions being mixed mode, so you can still use a “legacy” horizontal VHF aerial for it….but vertical is also good. We went thru the transition from having just 1 main VHF mast, to having several available in different directions….ditto for DAB. so the Omnidirectional aerials are critical in order to receive from all transmitting masts……ideal for most people. but I have to point out….omnidirectional aerials have much less gain or are much less sensitive than directional ones. So if anyone lives in a remote location…you may still be better to go with a directional, multi element, vertical aerial for FM and DAB. That said, being remote isn’t too much of an issue-it is what is between you can the transmitter that is more important.
@g4nsjАй бұрын
I think all FM transmissions use circular polarisation these days. Remote locations would definitely be better using a Yagi aerial. I think vertical aerials are popular because, where I live for example, there are several local transmitters in various directions. All the best, Ray.

Intresting vid, especially about sealing the connection box on the antenna, I installed a 3 element FM aerial on the gutter board of our house, near Portsmouth way back in 1989, sealed the box with silicone & that aerial is still in use today! It picks up all the stations from the Isle of Wight transmitters ( Rowridge for the BBC & Chillerton down for the commercial stations), plus various other local and not so local ones. Also in the summer with the right weather conditions I can often receive Stations from afield & France too. I use a Sony Hifi tuner with a handy feature - it has 2 FM aerial input sockets, switchable from the front control panel, so I can if need be connect a different aerial. On the subject of DAB, I've got a similar Roberts radio that has that removable cover on the back , although I've never unscrewed it, I'm not a huge fan of DAB radio, mainly due to the low bit rate & poor sound quality of many stations now, even the newer DAB plus ones don't offer much improvement in audio quality, my next kitchen radio may well be an Internet one, although I often stream stations from my phone to various Bluetooth speakers anyway.

Last year I installed a very "simple" outdoor-antenna for FM on the balcony of my flat in a skyscraper (10th floor) here in Germany to get a good signal into my Yamaha HiFi-receiver, after they switched off FM broadcasting via broadband-cabel... I'm lucky to have over 30 FM-stations here (more then before via BK), but inside the skyscraper-flat half from the opposite direction of them are shaded by the massive building (especially my favorite Rock-station that's 180 degree behind the building). I go best results by just installing a SIMPLE Lambda/2-"wire", also VERTICALY (which is not optimal, but receives all around). I feed the coax through a window-adapter flat-coax to the inside, and mounted the coax through the baseboard to my stereo. Sometimes a few stations have little static (depends on the wheater), but most of the time I get nearly ALL of them in good Stereo+RDS! :)

interesting about that bit of orange wire. I've just been restoring a 60's compact valve radio. I was getting a bit of distortion/sibilance on FM and I'm in the attic room. I was eyeing the circuit, maybe an alignment issue. Then I had the idea of throwing some wire out of the skylight. Didn't have any coax so just used some house wiring cable. 10ft outside, just lying on the roof and 10 ft inside. It's not entirely eliminated the sibalance but certainly improved it.

Hi Ray, I was interested in how you handle the 2 signals from both antennas and using a switch to change between the FM and the DAB signal. A simple solution is to use a 2 way "F" splitter and reverse it. That is, to connect the 2 incoming signals on the "output" side of the splitter and antenna cable to the receiver on the "input" side of the splitter. This combines both of the signals onto the single cable. You can do the same with FM and television signals onto the same antenna feed.

I bet it would have worked fine for both without any problems. I don't have a chimney on this house, that is a bit annoying! I pt a pole up on my shed for a dish, but I should have made it longer, but when the dish was mounted, they put it so near the top that I can't extend it a bit to hold other antennas. Bit annoying, I wasn't here when they did it so I had no say in it, but I will put up another if I find a scaffold pole lying about somewhere. They used to lie about everywhere, but I never see any these days! Shame, I might even have to buy one lol. Nice to see you here Ray once again.

Hi Ray, thanks for sharing another interesting video. I am not sure how well DAB DX performs here, as I don't own a DAB receiver, apart from a tiny pocket one. However, digital TV tends to lose channels, when there is thick cloud or rain happening nearby. I am guessing that DAB may have similar problems during bad weather. With the bad static increasing on AM radio, outside aerials may even be soon needed there as well. For FM reception, I use a Matchmaster outside antenna horizontally polarized on a rotator. This also prevents unwanted local FM overload, when checking for DX. Anyway, take care and all the best. Rob.

The radios might be getting better, but the broadcast bit rates seem to be getting worse and worse, when you think of the brilliant high quality stereo VHF you used to get in the 70s and 80s compared to the audio quality on DAB now. I'd skip DAB and go straight to internet radio and then if you have wifi around the house (plug in wifi repeaters are cheap) then you have a high quality portable radio with much more choice and no outdoor aerials to wire up.

Then you push the screen back on itself until it is covering the remaining plastic screening for 300 mm. Tape it down and mount it vertically. So the backfolded screen is anti-phase to the protruding inner core, producing a balanced aerial. Have you herd of this? It has improved my DAB, but not cured the dropouts totally. Can you suggest something better?

please i have ST-15B fm transmitter which i wanted to use for a small radio station. and asking if i can use the normal tv antenna to my transmitter

Fairly recently I set up an external antenna so I could receive a decent signal from the FM community radio station I manage, about 20 KM from where we live. My initial experiments used an old TV "rabbit ears" type antenna spread out so it was set up as a vertical. That worked really well, but for the final setup in a different location on the property I got the best signal by putting them in a V configuration, basically how you would typically deploy rabbits ears on a telle! Now my question to you is that although these rabbits ears are nothing more than two telescopic rods, they are connected to a short piece of 300 ohm ribbon feeder and then into a balun before going through my coax into the radio, this being a surplus car radio set up as a base receiver. Should they actually be terminated with the ribbon feeder and the balun? Since they are not a *folded* dipole wouldn't they match better directly into the 75 ohm coax and give a better signal that way? Or, since I have them set up in the "V" configuration does that change the characteristic impedance of the antenna, making it more like 300 ohms, hence the ribbon & the balun?

I wish that our American Digital Radio standard Called HDradio was as popular here as your DAB standard is there in the UK. It would also be nice if the FCC would tie the new ATSC 3.0 standard to Digital Radio and allow digital TVs to receive Digital radio and smart car head units to receive Digital TV.

Hi and thanks for your informative video.I fitted a 75 ohm coax socket to my Grundig DAB radio ( all I had) which hasnt been much use since I moved house. It doesnt like the chassis being connected to the ring of the socket and prefers it left off.Can you explain why this is and will it be a problem when I eventually get my dab aerial installed.It works with a conventional TV aerial after testing.Can I connect the ground to the chassi via component?Thanks
@g4nsj5 жыл бұрын
Hi Alan, to be honest I don't know why that should be. Connecting the outer of the coax to the chassis should be fine. Try using a capacitor between the chassis and the outer ring of the coax socket. Perhaps a 0.0uF or something.

Hey Ray, I live in the U.S., not sure I am familiar with the term DAB. Is it a digital mode or something we in the states just call Internet - or Cel signals?
@Gubel19904 жыл бұрын
You in the U.S. only have IBOC/HD-Radio, which is just a further side-carrier on top of a regular analog FM station that carries digital data-streams - nothing special here with the antenna (VHF Band II, 87.5-108 MHz). DAB+ here in Europe is a separatr digital-only standard for radio broadcasting, that also can carry multiple digital AAC-compressed audio-streams. It ist standardized to use the VHF Band 3 (174-230 MHz), that earlier has been used for analog PAL-B TV-transmission. It also keeps the old channel-spacing of the earlier TV-channels (VHF 5-12 here), and breaks them further down in quarter (A/B/C/D). So you just need a VHF-3-Band antenna to receive those channels properly. FM runs independantly on VHF-2. So you have to deal with two different antennas (VHF3 about half the wavelength of VHF2), and even (mostly) 2 different polarisations (FM mainly horizontal here, DAB mainly vertikal).
