Hello, I would like to start with amateur radio, but only passively, listening on all possible bands.
Unfortunately, I only have very layman's knowledge about it, I therefore want to ask you to refer to some practical literature or specific advice.
I would like to own some review receivers and in the evenings in the dark to listen and monitor the tuned frequencies, I just don't know how to accept it, what frequencies should I focus on?, what can be heard on them, first of all, what kind of antenna will I need?, unfortunately, I live in a panel house in Bratislava in Parzalka on the ground floor… but I also go to Lipt Mikulas.

as a listener you have a choice of a whole range of receivers. You just have to decide, what would you prefer. Whether searching and listening to radio stations (na DV, SV and KV), or listening to amateur radio operation on KV (but also on DV and some VHF bands) or listening to some specific professional services (such as airport beacons on DV etc.).
For listening to radio stations, one of the overview receivers allowing listening to AM in the DV ranges will suffice, SV and KV (cca do 30 MHz or slightly higher). If it has the possibility to change the width of the received band, it's a big advantage. There are plenty of receivers of this type on the market.
A receiver capable of receiving unmodulated telegraphy is necessary for listening to traffic in radio amateur bands (CW) and phonics with one sideband (SSB). Another requirement is the ability to change the width of the received band. Either a receiver from an army sale will do here (somewhat bulky equipment and difficult to transport), or one designed specifically for radio amateurs.
You can read some information on the pages for listeners, e.g.
SWL info … http://swl.czechian.net
Czechoslovak DX club … http://www.dx.cz
Or a local radio amateur can advise you.
There is no need to worry much at first with a reception antenna - even with small antennas you will hear interesting things at first and later you will be equipped according to your needs.
I wish you the best of luck in the beginning.
Josef, Category QRPWe made the first historical connection via a converter, you can find a lot of interesting materials for beginners on the site http://www.hamradio.sk/zacinajucim/zacinajucim.htm .
Spring.Joseph, Spring, thank you very much for the responses, I will read some articles to at least get my bearings. I would certainly enjoy listening to everything that is outside of everyday consumer broadcasting, especially remote exotic stations, radioamaterov, lighthouses, police, aircraft, everything :).
I understand that I have to choose something more specific, Unfortunately, I don't have €5,000 for expensive broadband receivers, I really like the ICOM ic-7600…Except it's like buying a plane and not knowing how to fly it. Even my probably not very good location and possibilities – the panel on the ground floor will probably tell me what maximum good receiver I would need, you probably deserve a better antenna and a better location, I do not know, I'm just thinking out loud.,
I am an electrical engineer, I make flat joints from 12 years 🙂 maybe I will find some suitable construction, but most of the time I was mainly devoted to NF and low-voltage electronics.In any case, thank you very much.
done.Hi Zdena!
I might have a solution for you. SDR worked with him. It is a relatively simple construction and I can hear frequencies from 0-30MHz, I can even see +-42khz from the tuned frequency, what are the other stations there.
You can find more information on the website sdr.ipip.cz, I specifically built a DR2B receiver from YU1LM.
By the way, if you want to know how it actually works, there is also online advice like this http://websdr.org
Good luck!We made the first historical connection via a converter
Online listening and tuning of amateur radio frequencies will allow you, for example 7 band shortwave Dutch project at http://websdr.ewi.utwente.nl:8901. There is also a globaltuners.com project, which also allows you to listen and tune the receivers of DX maniacs all over the world, 2 subsequently, he devoted himself to the construction of the transmitting and receiving HF equipment 3 they are also in Slovakia. I'm not dissuading you from building or buying radio, but this way you can at least get a taste and then decide for yourself furtherTone
I also decoded the APRS from ISS several times, but I haven't been able to send it to a large antenna yet, those web SDR advise, it's a paradise, this is exactly what I will enjoy, but it will probably have even more benefits when I have to receive it physically, although the waterfall display on SDR is a good thing.
I have already found an article in amateur radio – we broadcast on amateur radio bands, I start reading.
I have to do some research on antennas, I'm at a loss and I don't know how to solve it, I found some miniwhip antenna, whether it should be effective for a beginner…Hey hey it's cool, you can also catch stations on a piece of wire. I live at 4. floors, so I threw 20 m of wire on the tree and I am listening cheerfully… 🙂
Anonym-Zdenci, I don't understand why it logs me in and out
Well, I will have to decide somehow, I definitely like the SDR Perseus as well, but also acceptable for reasonable money, ICOM IC-718, Ten-Tec Receipt … I am already preparing a huge map for the wall and I will make threads like in the movie Contact. 🙂
Good luck Zdenek, I would also like to point out a little, that in big cities it is mainly on DV, Quite a high level of interference in the SV and lower KV bands (discharge lamps, city transport, various undisturbed appliances and many others). Just so you're not too surprised at first, that you are far from hearing it, what did you hear about it “internet radio” and that sometimes it is “shorter antenna better, than the longer one” …
But if you have the chance to leave (at least for the weekend) out of town (or to a smaller town), you will probably be satisfied …
Just – you have to feel it, find out what to hear where and how …
If you decide to buy a good radio – it can only be approved …
I wish you much success and well-being in your initial steps into the world of radio waves …One more addition – the devices you mention are transceivers (but you probably know that …) and so you should avoid it if possible, to try (albeit by mistake) transmit to a non-adapted antenna – it could easily happen, that you would really only have a receiver from it …
😆 so operate without a microphone … that's pretty much a certainty … 😆There may be more noise when receiving the cable,
yes, that's what I thought too, they are probably well geographically located with decent antennas, I will admit that I am always more of a pessimist than an optimist, I realize that a good reception depends on my knowledge, constant attempts, experiences..I might be able to place the antenna on the roof of the panel house and run the wiring through the stanchion..there could be a decent antenna on the roof.
How do you write?, I'd probably rather buy a scanner like TRX so that it doesn't happen by chance that I'll be tempted to put something on the air and I won't have permission yet..
I quite like the ICOM IC-R75, supposedly, the YAESU VR-5000 should be somewhat worse, I understand that these are incomes in some medium consumer class, I'm still finding out, to another, I don't buy anything, I also have to wait about a month or two to settle the finances so that I don't risk €700 unnecessarily.
Brief description from the manual: The RF-10 radio station is a company portable HF radio station, intended for command at company-platoon level. He carries and serves her 1 man.
Origin and warning: This radio station was used by the Czech-Slovak army, it is currently being replaced by the more modern RF-13, but it is probably still in partial use. At the beginning, I want to point out, that this radio station is not homologated and the frequencies on which it broadcasts are not accessible without a license, therefore use it only at your own risk. I managed to find out, that it is best if you broadcast on frequencies from 46 do 47 MHz, this band is referred to as dead and only some companies use it. In the forest, you shouldn't disturb anyone with a long rod antenna anyway, but still follow the rule – speak only when necessary, do not say your names, in case of interception of a foreign signal, change to a pre-agreed frequency. Above all, do not broadcast near military units. Even if they don't have the necessary meters for that and don't even have time to find out your location, zbytočne nerisujte – there are nice fines for that.
Where to buy: It is paradoxical, but it seems that the army sells these radio stations despite the ban. Most often, someone sells them on the Internet through advertisements, quite a few in Slovakia, but if you look on the Czech internet you will certainly find many people, who sell the RF-10. I even looked through a military clearance catalog once (Slovak military unit) and the RF-10 was also sold there. So it's not quite clear to me now, why does the military sell it even though that frequency is not allowed. But you probably won't catch much in the future, since modern radios have coded broadcasts.
