I did some experiments in the past (around 1997 ???). Not allowed here in The Netherlands. I made soe contacts here localy over 30km with a yagi. When there was tropo conditions during the summer I made QSO's with the UK. (600 - 800km). I'm not active anymore on that band. I did sell the radio's.... Interesting time when building yagi's for that band...
totaly usless for mobile ops at this freq range unless you have one or more repeaters to work with,that why mobile phone companies have so many nodes all over to get the coverage they need for mobile users,,,i reckon 934 was doomed from the start due to high cost of radio,s etc,mobile phone firms still own this part of the spectrum,dont know if they use it anymore,but intresting anyway,,i do like to work uhf mobile.
@daddymalony I have seen a 934MHz QSO from North Staffordshire to Jersey, clear as a bell, but that was rare. From the same spot I never managed to hear anything coming from Jersey on 27 MHz on many occasions, although I got second hand reports of being heard there. That was straight 8 watts or less on the 934. Most of the time though the range is quite short, strongly attenuated by anything that gets in the way of a line of sight path.
In the United States the amateur radio band is 902-928 MHz. Although repeaters are absolutely necessary for any real ability to talk with any distance, site-to-site, or simplex operation, is unrealistic because of the characteristics of frequencies in that range. I use converted Motorola radio equipment with 30-watts RF output (mobile), and even that isn't enough at times! My portable is also a Motorola commercial radio with 3-watts RF output and is only good for limited range. Great stuff tho!
I can cover CB/934/81 20 + 20 and also soon to be getting a Vertex 800MHz radio for the SRD channels.
I think it's about time we fought to get a band around here back. The stole it from us just as equipment was beginning to get affordable and yet there are many unused gaps between 846 and 935MHz where 40 channels could be squeezed in for the enjoyment of citizens all over Europe.
We need a regular activity day. I propose the second Sunday of each month.
If the isobars run from your station to Holland and Norway, and you are running good yagies, you have very good probabilities of making reliable regular contacts over that distance especially if you can work local coastal areas in that direction.
There also needs to be a known Sub Audible common tone to ensure that strong GSM signals do not open up the squelch. CTSS was not installed in the old 934 radios that als had wider deviation and frequency drift that is unheard of today.
Across the UK there are still many active users. The problem is that if tell that to most people, they immediately turn on their radio or scanner and say, "I can't hear anyone" so that can't be true.
Now, you need yagies, the question is, is everyone going to go Horizontal? or remain vertical?
Now, radios have CTSS codes, narrow deviation, that allows many more channels.
If more people use it, they will get it back, its the old story, use it or loose it.
I also worked the 934mhz band for a short while and made some good friends who i never got to meet. I sure remember you though Frans and its been a very long time. I wonder if you remember me as i was also in the 934mhz club uk.
I own a Reftec,a Delta 1 and a Comtel all boxed as new plus a Nevada SWR bridge and twin Yagi beam........never run them,but meaning to take them to high ground, just to see if I can hear any stations???........DAVE ,North Lincolnshire.
Yeah I have one of these, but Never use it as Im aware that it is illegal to operate etc etc, apparently mobile phone companies have bought this frequency in the UK, anyone know this if this is true?
K0BBF, you are incorrect. The term CB applies to radio services on several bands. In the US alone it has applied to radio in at least three different bands, 27, 157, and 460 MHz. Today only the 27 MHz (ok, 26.985 to 27.405, Class C CB) band is still used.
In other parts of the world there are several other bands still in use today.
The 934 MHz stuff was a UK specific thing if I remember right, maybe including AU.
The Net (and youtube) is a World community, think beyond your borders.
934MHz UHF CB was UK only, though tests were done in Germany in the early 90's, plus there were some Dutch ops. Oz & NZ have 40 channel UHF FM CB centered on 477MHz - 27MHz kit is very hard to find 'down under' now - in OZ anyway. OZ also has hundreds of repeaters and '477' is still very much used with GPS included in transceivers. '477' got in *just* before mobile phones took off. Several other Australasian nations have derivitives of 'OZ/NZ' UHF CB on different frequencies, as well as hf & vhf
Australia & now NZ have 40 uhf CB channels centred on the lower & more affordable frequency of 477MHz - with hundreds of repeaters in Australia, where GPS is built into uhf CB radios. Other Australasian nations have similar 40 channel uhf CB, but on different frequencies like 450MHz.
In the US, CB started after WW2 on 400MHz, and today the 23 channel G.P.R.S. system works on 462/467MHz - with repeaters.
FT, here in the UK we have 2 legal 40 channel 27MHz allocations, the one you mention [= US class D?] and the UK only 27.60125 - 27.99125, both fm. NZ has hf CB on *26*.330 - *26*.770MHz. Different countries in Europe have different specs. despite wanting to be 'harmonised'. Germany has an additional 40 channels below the US standard channels.
Delta 1's drift until they warm up, they have a crystal oven. The 27MHz radio was a Bluebird, the transverter was a Grandstand. 934 in n London was busier than the entire 12MHz of 2m & 70cms, yet 934 was withdrawn and the underused ham bands were unscathed!!
I used the 934 MHz band in the early to mid 90's & what a superb band it was, good range & crystal clear quality, the range during lift conditions was 100's of km, sold all my gear in 96 regret it dearly now, been a licenced ham since 92 & still reckon 934 was the best band of the lot, located in South Liverpool here........934 callsign was CA148
Why do people say 934Mhz has been sold to mobile phone companies when at the time of writing [Sept 2008] it's still CLEAR and UNUSED. In the mid 90's, there was more activity on 934 that the entire 12Mhz of 2m & 70cms combined - yet 934 was withdrawn and the amateur bands were allowed to carry on..... Should have been the other way round. Used Cybernet Delta 1 radios changed hands for between £200 - 300, now they're being given away..... Best band going with no idiots and very dedicated ops.
That's one band I wish I'd tried. After they legalised CB, it became unusable on 27mhz for several years. Too crowded, too many idiots. I imagine there were some good ops on 934, and it would've been interesting when there was a 'lift' on the band. Contacts over long distances possible.
A 16 bay stacked J-Pole would have about 11 dBd gain. 934 is not the best choice for communication in a omni area. Try a yagi (or 8) and quite possibly you'll get 100 km that way. Feedline loss is KILLER at that frequency....hardline is best. Good Luck.
whwt with the tiny antenna required,I can't help thinking this was a missed oportunity,I heard these 934 rigs were really expensive compared to the 27 rigs is this true and could this have been why no one took this up???
you still see these rigs on e bay they don't really fetch a lot,I saw one that was a homebase,a bit like a harrier cbq to look at. maybe it would have had more success as an amateur band? Today it could still serve a purpose as a band for the elderly and infirm,it may give them some companionship if they don't get out or see anyone very often,just a thought.
I've got a few old old cb mags with a proposes idea of 934 being the new way forward. As far as i can remember it was only a short range level terrained frequency. I must did them all out for old times sake.
Am up and running on 934 in the leicester area. Using homemade dipole but hoping to make a beam soon. Have two Cybernet Delta's and hoping to put one in the car.
I did some experiments in the past (around 1997 ???). Not allowed here in The Netherlands. I made soe contacts here localy over 30km with a yagi.

With good propogations it was easy to reach them from Holland.

the reftec radios were lousy
the cybernet deltas had significant (25KHz) drift problems
anyone remember the 27-934 transverter (was it a reftek bluebird ??)
but yes a great band - that didn't get used - and got given to someone else who had a use for it (as we - the public didn't have one!)
remember that 70cms and 23cms users !!
I just swept 934MHz on my analyser and I can see 200KHz wide GSM carriers - so it seems to have been used
cheers for now
