Title: Links to official Govt sites globally which specifically state approved freq.
Post by: rcforall on August 02, 2009, 12:27:33 PM
I checked and found this on a site :
Quote
A certain number of radio frequencies have been designated by law for use with rc airplanes and aircraft being controlled with an FM rc system (ie not 2.4GHz). They fall into the 72MHz band and each separate frequency has been giv
en a unique channel number.
Unquote

But can  you we make a collection of official of links to official site from around the world which clearly specify FM OR 2.4 G .
Guys I am not internet savy like many of you  so I think many of you guys would be better at links .

In fact this could be a WIKI .
It will be the first step that will help us to document  and  form a country wise data base of approved frequencies.
This could be used in making a presentation to the govt.

The next step as per me would be to approach the concerned authority thru some organization like aero club of Pune etc to seek govt approval and clarification on this and then request for frequency allocation for aero modeling.

US AMA - http://www.modelaircraft.org/events/frequencies.aspx

Britain BMFA - 2.4 specific (upto 100mw) - http://www.bmfa.org/publications/24ghzguidance.html

BMFA - 35Mhz etc details are part of their guide book -  http://www.bmfa.org/handbook/Handbook2007.pdf

FCC is the approving authority in the US like WPC is in India. AMA is not govt website.

@Sai please note that the policy is very clearly laid out. there is a standing committee on frequency allocation and the manufacturers of radio need to approach them.

Also kindly note that the power of the radio like 75milli watts etc is country specific for example US has a certain norm and countries like Germany or UK have different norms. The actual rule is that the radio manufacturers need to adhere to these country specific norms.

The problem in India most modellers buy radios from abroad or when they travel. Even WPC has laid out norms.

Regarding FM radios not allowed is not true. The radio manufacturer needs to approach the WPC with all relevant data and application with the samples of radio and have the same tested and all relevent data of the frequency modulation that manufacturer use needs to given to WPC and if they feel its OK they will allocate the freq. after the same has been approved by the standing committee.

Wonder if dealers like RC Dhamaka or the vendor itself (Airtronics) have got their sets sold in India approved by WPC ?  If any manufacturer/dealer can confirm this, that would really be good news, and end to a lot of speculations.

Most developed countries have the freq. allocated

Like for land vehicles will have a particular set of freq, so will Airplanes/Helis/Sailplanes will have theirs, Boats will have theirs, etc.

Most countries like Japan, Australia, New Zealand, Europe ( Different Countries), USA, Canada, Brazil, Singapore, etc all have country specific freqs.

@ anwar,

kindly note that to posses a delicenced freq radio is not a crime but where the radio has licenced band to posses it is a crime.

The Only delicenced freq is the 27Mhz with specified channels & 2.4Ghz

You are aware that you cannot fly 72Mhz in UK. so the same goes with India

Not sure what that meant.  Specifically, in lawyer speak, "possess" is completely different from "use" or "operate".

There are two issues;  [1] a particular band being allowed, and [2] specific equipment in that band being approved.  That was the gist of my question.

The reference to RC Dhamaka is incidental. That applies to any body selling radios here.

And even more interestingly, what if a radio seller approaches the WPC asking to approve a radio that is in 72Mhz, at the same time explaining how 27Mhz is practically dead ?

Would that trigger a process that will eventually get 72Mhz added to the list of allowed frequencies (27Mhz and 2.4Ghz) ?

Or should we expect outright rejection and shut doors ?

In my opinion it may be considered. The freq allocation is with the standing committee in WPC the standing committee has been appointed by the ministry of Telecommunication.

Katty ,
This thread is not to argue about what is right and wrong

What you have told is nothing new that we have not discussed or don't know .

Lets get to the intention of the thread to build a data base of various countries and their approved frequency.

So we have USA and UK now , what about other countries and their official notifications.

So Katty finds some links that will be useful to all of us.
