At 27 MHz and a distance of 1000 km, propagation will be the main determinant of the possibility of communications. Propagation will primarily be a factor of time of day and the sun spot conditions. You can get a fairly accurate estimate by using propagation prediction sites such as VOACAP. If your interest is exchanging messages between stations, one of ...

When you ask if a QRP transmitter could be used to solve your problem, I presume that you mean a low-powered transmitter on HF, meaning roughly 3 – 30 MHz. That would solve the problem of limited range associated with the VHF and higher-frequency bands, but a large antenna would be necessary. The problem is that radio spectrum, especially in the HF ...

As mentioned in a comment, if you ask a legal question you need to give us an idea of where you are. Please add a country tag. However - this is one that’s not hard to answer without knowing where you are. Generally, around the world, if you are to transmit as a radio amateur in any case apart from an actual emergency, then you need to be licensed in the ...

The purpose for licensed ham radio in and of itself is education (whether for self or others), experimentation and for recreation. So yup, to transmit, you'll need a license (at least for the US and UK). You can, however, listen to ham broadcasts without a license (at least in the UK, where I'm familiar with the laws)

Welcome to ham radio! Discussion of some of the simplest and most common forms of ham radio antennas (aerials) begins on page 72 of the Study Manual for the Restricted Grade Indian amateur radio licence. The half-wave dipole may be the single most common amateur antenna at HF because it is simple and inexpensive to build, easy to erect and almost 100% ...

I strongly suggest that you begin with a one-band radio kit. There are several manufacturers and the cost is likely to be quite reasonable even with shipping. The main reasons are: to get on the air as quickly as possible. Even a little experience with real-world operations will likely change your view on what you want from a radio. The main obstacle to ...

Two things here. Per the 1984 amendment to the Amateur Service Act vide. GSR#1225/84 An SWL licence is required to use a communications receiver. This is available 'upon request' from the WPC for a nominal fee Caveat Emptor This category of licence may have been superseded by a later amendment made in 2009/2010; let me ask around and get back to you The ...

I would say, your task is a challenging one, but not unsolvable. 27 MHz CB radio band should work similar to 10m amateur radio band. I suggest to start with simple experiments. For instance, solder a simple oscillator. In my experience Clapp oscillator is quite simple to solder, see schematic in this article https://eax.me/clapp-oscillator/ . Then add a 555 ...

As you say in your post, that this is urgent, there are plenty of options for you to find out information quickly: Contact the Amateur Radio Society India. Contact the Wireless Planning & Coordination Wing of the Ministry of Communications and Information Technology, Department of Telecommunications. Other than that, you can obviously download the ...

If you are just transmitting GPS coordinates and at a slow rate and need a bandwidth of about 50kbps or less then have a look at LoRa technology. It is low power, low data rate and spread spectrum but it is very reliable with a range over 10km (some as far as 50km) on licence free VHF and UHF bands. It is designed for IoT uses in a noisy environment it could ...

Licensing and tests vary per country. Amateur radio in India: https://en.wikipedia.org/wiki/Amateur_radio_in_India Licensing in India: https://en.wikipedia.org/wiki/Amateur_radio_licence_categories_in_India I couldn't find any practice test questions for the Indian tests, but there are a lot of questions free on-line and in book form for the U.S. tests. ...

Hmm, I want to say no. Here is why. If you answer is clear if you intended to operate and radiate then yes regardless if it is educational or not then you need to get a license.

The Wireless Telegraph Act 1973 says: “The receiving apparatus of any wireless telegraph shall not be used for any unauthorized reception or interception of wireless telegraph communications”. I suspect this is more to do with listening in to police or aircraft radio (for which two UK plane-spotters [were] charged with intercepting communications in 2010) ...
