70MHz also called 4mtr Hamband
« on: July 26, 2014, 03:52:54 AM »
Hi friends,


I am wondering if there are any hamstations interested in 4mtrs/70MHz.

YES i realise that it is not a Hamband in Thailand at this moment, but possibly some
of you guys are already listening for DX.

When you have never heard of this Amateurband then visit this website http://www.70mhz.org
and here you find the worldwide allocations  http://www.70mhz.org/index.php?categoryid=2&p2_articleid=316.
Band usually runs from 70.000 to 70.500 MHz with some exceptions. 

There are about 35 countries/DXCC's active and every year there follow more.
Possibly you guys can start with beacons and spotfrequencies to open up the band.

Tnx interest in reading this.

The main problem with 4m is that it's only allocated in IARU region 1, which is Europe, Africa and the Middle East. That pretty much means there is no chance of 4m being allocated to amateur radio in Thailand in the foreseeable future.

However, just last Thursday! Thailand was granted the use of 50-54MHz (6m), 430-440MHz (70cm) and several microwave bands, starting with the 23cm band. Also, the 2m band was widened by 500kHz to 146.500MHz. See here for the full Thai band plan: http://www.qsl.net/rast/text/2014HF-VHFbandplan.html

This is great news for radio amateurs in Thailand :)

Hi Scott,

Congrats on these expansions.
You will all enjoy those, no doubt  :)
 

I am aware that 70MHz is "not yet" a Hamband in Thailand.

The same for USA, but as i proposed in my initial write up here, they have a beacon and why not start that in your country as well?

It will give a good possibility to check propagation.

My best ever heard DX from Europe on 70MHz, at least one i did get positive identified, is a Taxiservice in Auckland New Zealand.
So 70MHz is a very interesting band and more DX to hear/work then you might expect.

To add to my last comments.

Here the website of a new Hamradio manufacturer and dedicated 70 MHz transceiver.

www.nobleradio.eu.

On the webpage you can download the manual and see pictures of the in- and outside of transceiver.
