12 weeks to 6 months to get a repeater on the air (rmc repeater report nov 2000)

Timescales for dealing with the various stages of the licensing process have been agreed, this being a major complaint for many groups.
The various stages are explained in the guide and if the new timescales are successful then from submission of correct and full paperwork to issue of an NoV should take about 12 weeks for a repeater where amateurs have primary use of the band to 6 months where we are secondary users. The majority of this time is taken up by the various Government departments involved, and really cannot be expected to reduce much. Having said that, recent approvals have been forthcoming so quickly that the groups concerned have been delighted, and certainly have not been in a position to place their units in operation.


applying for an internet repeater link NOV?

The RA has requested that full details of stations being used to provide Internet links to repeaters be included on all future applications. The following data is required: -


presently pete g4bvv links the repeater most of the day on a dialup to irlp but that will change when a new NOV is issued and it will be connected on a high speed link.- this will make reflectors available again, as you cannot connect to reflectors using a dialup connection. we have had to apply again for a new NOV as the first application to the rsgb repeater management group got lost.

Slow take-up of 7.6MHz spaced repeaters on 70cm from (repeater report nov 2000)

In spite of obtaining agreement in principle for 7.6MHz spacing repeaters on 70cm take up has been disappointingly slow. As yet no dedicated Internet repeaters have been proposed in spite of the supposed demand earlier in the year and we have processed only one additional "normal" unit. So come on guys; we have done our bit by clearing the way; where are your proposals?

more 2m channels for internet linking

about a 9 months ago ukirlp asked the rsgb for more 2m frequencies forinternet linking we have never received a reply. as the ra subcontract this work to the rsgb it is little disappointing when we don’t even get a reply from them - we may have to write again

rsgb rmc committee member on Internet linking from the rmc minutes 21st april 2001 http://www.coldal.org.uk/mins0104.htm

We have received an application from M0AZM to join the committee as a VoIP expert. M0AZM will be invited to the next RMC meeting. ian norton m0azm now appears to have resigned so the rmc are still looking for a person who is a voip expert for internet linking projects

new irlp nodes

2 in leeds july 2002

1 in carlisle july 2002

articles on irlp

g3zhi has had an article published about irlp in ‘world radio’ which is an America ham magazine

articles have also appeared about irlp in cq vhf may 2002, radcom and radio active

other linking systems

eQSO and eCHOLINK and iLINK are windows based programs that can be downloaded from http://www.qsl.net/g3zhi and can be used for chatting to other hams on voice from your computer requiring a microphone and soundcard attached to it. 

sstv experiments

sstv experiments have been carried out using sstv over the reflectors and simplex links while it is ok to transmit sstv on some repeaters in the usa and vk it is at the present time it not ok to do so on repeaters in the uk so that must be avoided . g3zhi has sent and received sstv pictures using berts g4nji’s kenwood vhc-1 sstv handheld unit with melbourne and palm springs california while out cycling. this was done using berts 145.2875 irlp simplex link in rotherham.

lottery grant

one radio club got 6,000 for new equipment so maybe it’s a good idea to apply for a lottery grant to help fund the internet linking project in the uk.

ra stop rsgb news on internet gateways

the RSGB has been informed by the radiocommunications agency that it is not in a position to agree to any Internet gateways carrying the GB2RS news service at the present time and for the foreseeable future. The Society, which warmly welcomes this type of innovation, is obviously very disappointed at this news, but understands that the RA wishes to consider a number of licensing issues before allowing this type of amateur operation. Further details on this announcement can be obtained from the RA. (rsgb news)
