This is a long document and at the end of it is the new licence terms and conditions.
Let's take the easy stuff first. You will be able to set up a gateway or repeater (with regard to licence class) with 5W ERP on primary bands with no NoV. This will be fully unattended. You will simply use your own callsign for this. NOTE: 5w ERP. This means you have to take the loss in the feeder and the gain of the aerial into consideration. This is simple enough to calculate and there are websites that will automate this process for you. However, there is no limit to the height of the aerial beyond the normal rules.
You will have to make sure that you are not going to cause interference with anyone else. You will need to look at the band plan and do your best not to cause issues with anything. If challenged by OFCOM, you will have to show how you came to that conclusion.
This is fine where we are the primary user. Where we are the secondary user, 70cm for example, you will still have to apply to OFCOM. in order to gain frequency clearance and possibly to get permission to be unattended. You cannot just set up a repeater or gateway on 70cm without doing this!
I will paste the relevant sections below to show this. I have confirmed this by email with OFCOM. Currently there is no mention of going anywhere else than OFCOM for this but I will report back if I hear anything different.
--------------------------------
Remote control operation
10. The Licensee must ensure that, when operating the Radio Equipment by Remote
Control:
a) any links used for the remote control of the Radio Equipment must be
adequately secure so as to ensure that no other person is able to control the
Radio Equipment;
b) remote control links using Amateur Radio frequencies must use frequency bands
above 30 MHz;
74
c) transmissions from the Radio Equipment can be terminated immediately
promptly; and
d) the Licence Number (as specified above) must be displayed on or next to any
unattended Radio Equipment located other than at the main station address.
---------------------------------
---------------------------------
Unattended operation
11. The Licensee must ensure that, when deploying Radio Equipment for Unattended
Operation:
a) any links used for the remote control of the Radio Equipment must be
adequately secure so as to ensure that no other person is able to control the
Radio Equipment;
b) transmissions from the Radio Equipment can be terminated promptly; and
c) the Licence Number № (as specified above) is displayed on or next to any
unattended Radio Equipment located other than at the main station address.
---------------------------------
Further to these in the draft licence, there is a section A3, Notice of Coordination. This states the rules when coordination is required between interested parties. The relevant section for our use is at the top of page 100
So, as you can see, it is not just as simple as putting a gateway or repeater on 5W ERP and away you go.
Be aware that most hotspots do not support VHF. You cannot, as above, simply put your hotspot onto your aerial and use it when you take the dog for a walk. To be honest, you should *NEVER* put a hotspot on a high gain aerial. The spectral purity of hotspots is poor to say the least!
I have filmed a video about all this and you can find it below.

Thanks for the clarifications. I'm sure this will help people understand the proposals more clearly. Ye, it is a long document but well worth a read.

No problem at all Tom. Thanks for the interest :)
ReplyDeleteIan, the extract from p100 that you’ve shown above refers to ‘repeater’, not also ‘gateway’. I think you may have conflated these. My understanding is that coordination is not required for a gateway at <=5W ERP; I infer that this is considered sufficiently similar to ‘normal’ use of this band as to not require further permission.

Hi Dave. I have emailed OFCOM for clarification on this and I will update the blog as soon as I have it. Thankyou for the comment. We all need to get our heads around this. :)
