I plan to buy some transceiver. I am mainly interested in CW operation (since I was a radio telegrapher in the army 🙂 ). I want to ask which band is most suitable for reception, or I would rather not buy a device that would receive on a band without activity. On which band is the most active CW operation and can very distant stations be listened to? I have a degree in electrical engineering and I unfortunately started to be interested in HAM only now that I have a cottage in the village. At first, I planned to 'patch' some 40m or 80m receiver because I know there issufficient activity. However, unfortunately, I do not have the necessary expensive devices like osc, gen. Unfortunately, I will have to buy some ready-made receiver or transceiver. But which band? 🙂 Thank you for the info

Transceiver = Tracing a receiver. It means it both receives and transmits, and if it doesn't have a brand, you waste your money 😉
In the HF band, what matters most is when you have time to listen, because some bands are open at night, some during the day. But if you want to listen to distant CW, i.e. DX stations, I would recommend WARC bands (10, 18, 21, 24.5 MHz), although the activity there is less frequent than, for example, on 20 meters. But according to years of listening, it's similar with CW. At 3.5 MHz, CW is harder to hear (especially during the day) because it's mostly a band for inland states, but around 14 MHz (20m) CW is nonstop, just like on other bands (including WARC).

Thank you for the reply. I was considering a transceiver because maybe in the future I would get my own call sign 🙂 Although I am already 30, so I don't know if such people later get licenses. Anyway, some receiver would come in handy. Do you know what I should get?

One more, maybe a stupid question for you: Do handhelds have CW operation for transmission? So I connect the key and go?

Most handheld stations are suitable for FM operation, the newer ones allow reception of other modes, including CW, but not transmission.

However, there are also small devices, e.g., FT-817 http://www.rigpix.com/Yaesu/ft817nd.htm or kits like TJ2A http://www.youkits.com/

Since telegraph devices can be constructed with just a few dozen components, there are several kit producers in the world, e.g.: http://www.smallwonderlabs.com/Rockmite.htm
http://www.fix.net/~jparker/wilderness/nc40a.htm
http://www.Elecraft.com/

So regular handhelds, can I only work in phone mode or possibly in packet radio? Nothing more?

Yes, that's right.

Technologicky by výrobca asi zvládol aj vyrobiť telegrafný handheld (niečo ako Dragon SS-201 http://www.thiecom.de/ae201s.htm), but these devices haven't really succeeded.

There are several reasons – due to battery power, the RF output is low, the ergonomics of control are challenging, and the parameters are weak due to the compactness and economy of the design. Moreover, the antenna would have to be external and connected with a thicker lead, e.g., a coaxial cable.

On CQ.sk you will find a description of Mizuho handheld stations. http://CQ.sk/modules.php?name=News&file=article&sid=67

I would consider, for example, the Elecraft KX1 to be interesting. http://www.Elecraft.com/KX1/KX1.htm or K1 http://www.Elecraft.com/k1_page.htm.

An overview of commercially produced devices is at http://www.rigpix.com/index.shtml . Among the largest manufacturers of devices are Icom, Kenwood, Yaesu, Alinco, Elecraft, and Ten-Tec.

Can you then receive CW with the handheld? Won't signals mix considering that CW requires higher selectivity?

Did you manage to study all the pages from the previous post in 40 minutes? Accept that a handheld is not a suitable device for CW. When receiving CW, you need not only selectivity, but you also need to write down amateur abbreviations and Q codes to know what the connection is about. Practically no one transmits in plain language; it would be very impractical during connections between amateurs from different countries. You can find receivers for amateur bands, whether single or multi-band, on the internet in hundreds of variants, from the simplest direct amplifiers to complexprofessional systems. You can even buy interesting kits that will fully satisfy you and will mostly work with minimal measurement requirements.

40min? I graduated from a secondary technical school (communication technology). I was a radio telegraphist in the army. I studied (did not finish) telecommunications management at university (a combination of telecommunications technology and economics).
I know the theory. Unfortunately, that war didn't give me much because the only thing I did there was sit in front of a receiver where the signs HXVH NVKL were repeated all day long. Occasionally, QTR, QRK, and a series of hundreds of characters appeared that had nothing to do with the communication protocol. We responded by phone 🙂 So that's where my interest in CW comes from. I have no idea about the technique and operations, so before I send the form to the telecommunication office, I want to get a bit familiar and of course learn. I started this topic because I hope that experienced radio amateurs will advise me.wink

The question is what you want to request at the telecommunications office. If you just want to listen to CW operation, you do not need any permission. If you want to send listening QSL cards, you just formally request the assignment of a listener's number.
If you also want to transmit, you will have to pass some level of exams, e.g., receiving and transmitting Morse at the required speed and quality. You will find all this in the relevant regulations.
Try to specify a bit more which area of amateur radio activities interests you the most and which direction you want to focus on, and you will definitely get most of the necessary information. Your original question only about the possibility of receiving CW is too limiting.

Definitely CW and also transmitting on HF (I would like to have some QSL cards). Also transmitting and receiving via PC. Phone operation does not attract me much. I don't know how it is with you, but here the laws have recently changed and Morse exams are no longer held. I can't transmit, I can only receive with a 60. I would really like to build a simple quality transceiver, but unfortunately, I don't have an osc, generator, and decoder. Just basic tools, soldering iron, multimeter… 🙂
I didn't know that call signs are assigned even for those who only listen.

Hi Janop, everyone has written something to you here, but it is all taken out of context. First, write from which city you are, and we will try to find someone from the amateurs whom you could contact, or we will tell you whether there is still a collective station in your place of residence where you could learn more conditions and, of course, help you in further development.

Regarding your questions, without PERMISSION you can only transmit in the CB band and that in phone or packet (but I don't know if anyone is still working there).
For operation in the amateur radio band and echolink, you need PERMISSION!
According to our concession. Broadcasting without a concession, now I don't know if it's an offense or a crime, but there is certainly a high fine for it.
The license is issued by the Slovak Telecommunications Office in Bratislava based on the conducted exams.

If you don't have the opportunity to become a member of the collective, next year OM3REU will hold summer courses for future radio amateurs, where all questions for successful exam completion will be covered.

As a listener, you can apply for a working number of a radio listener from the Slovak Radio Amateur Association in Bratislava on Wolkrova Street without exams.

It is very important that you do not become an 'internet radio amateur' and if possible, get involved in some radio club. That's basically everything in a nutshell.

About 50m from me is OM3WKS, but I don't know him personally, just by sight. Maybe I'll approach him. We'll see if I find the courage 🙂
