When CB was legalised in 1981 two bands were made available, 27MHz and 934MHz. 934 never really caught on and it was withdrawn a few years ago. I'm told there are still a few die-hards using old 934 rigs out there but as few rigs were ever sold it'd be a miracle to find anyone to talk to. I think that freq has been reassigned now anyway, so [a] it's more likely to attract attention and more likely to have interference. |

I have a Reftec,Delta 1 and a Comtel all as new and boxed and a stacked beam, but never tried them.in 1999 this band was withdrawn for use ,but its very good if you get high up (Line of site ) as its Microwave band.You need top notch coax like Andrews Heliax and propper "N" type connectors.Your PL259s are useless much above 144 MHZ.The equipment was very expensive in 1981...£400 for the radio!!When EU Midband was legalised in 1988 the RA (now Ofcom) gave them 11 years to stop using the band and from that date no new radios were built.Its a big mistake in my eyes as the operators were true enthusiasts ,and operated like radio amateurs.I've been thinking of taking a radio and beam on the hills and putting a post on UK CB Radio forum on Yahoo groups as theres still some guys on there and see what I can do......I know its not legal and they said mobile phone were on there.......well maybe the old ones ...but not the digital ones now!!!!.Any gear that comes on Fleebay fetches propper top dollar,so unless their collecting it like me.........somebody must be active!!! :rolleyes: |

There has been quite alot of 934mhz equipment on ebay lately. My guess is though that the band is dead. So unless we can string a few of us together and give it a go, that would probably the only way you might get a contact on there. Also at that height in frequency it will only be line of sight, so beams are the only way in the hope of making a decent contact. I was working with 70cms (430mhz) last Sunday and managed contacts with vertical polarization to stations on high ground easily. Furthest was 65 miles with both reports each way at 5/9+. So on 70cms on high ground you could easily on 10 watts vertical make 120/150 miles again depending whats in the way. With beams, well that could increase significantly. I know 934mhz is twice the frequency but i still think you could make a good distance running horizontal. As for mobile phone use on the band, i'm sure most phones are on 1800mhz now? Only way to find out i guess is dig out that 934 set and have a listen..que Dave

As far as I'm aware, 02 and Vodafone operate around 900Mhz and Orange and T-Mobile operate around 1800Mhz. Pretty much all phones these days are dual band so they can operate with different networks (some are tri-band and quad band too for use abroad). Which explains why T-Mobile users always have to run out of a building to make/receive a call as the building penetration of the 1800Mhz signal is so poor - I think Orange is better due to having better coverage. From what I've read, the word is that the 934 band is still clear, but I've not read a definitive answer on the subject. Cheers Gary |

i know this is a late reply but there quite a number of 934 operators around where I live and ive got a delta 1 and a base antenna also a mobile antenna .heard that you can use old cellphone antennas the glass on glass type work apparently so if you buy a car with one hook up your 934 rig and go mobile!

I believe you're right! I think the band is used by mobile phones now, T-mobile I think! |

My Reftec 20 channel..not the best, but tidy enough and fully working

I have a double side by side Yagi with like a mesh reflector on the back. I also as in a previous post have a Reftec ,a Cybernet Delta 1 and a Comtel. I was lucky enough around 5 years ago to buy a Nevada 934 SWR bridge from Knights second hand of all places. Try and buy some Andrews Heliax coax Mark and top quality plugs. Your skytronics RG58 (not that you use such junk......LOL) is no good up near 1GHZ.I see antennas and radios seem to fetch big Bucks on E-Gay . As for mobile phones. As far as I understand they moved when went digital. So could be worth an "Oldskool " Net. But as everyone knows........it's not legal now as it was back in its day.......but I guess pulling wheelies @ 100MPH on a Gixxer Thou is'nt neither......a risk some will take I guess !!!. Just remember showing your CB934/81 badge will not wash with "Grandson of Buzby". |

Finally have myself a stick for 934 mhz (well spotted Trev at the Dunton Radio/Boot fair thanks mate) Will hook it up to the Reftec and hope for the best....lol. Stick will be mounted in the loft just for the time being, then perhaps another antenna on the chimney stack Will i hear anything at all???? Simon Wizard ...when does the activity start on channel 7in the summer time? any other tips are greatly appreciated ....thanks in advance   EDIT....Obviously this is for RX purposes only Edited by Mark in Essex, 24 May 2011 - 08:22.

Using a Reftec 934 here and antenna for the band. Listened to Ireland on Channel 8 the other day but was not at all possible for the reply. There is a Swiss net still runs channel 7 some saturday evenings but also sometimes not on air as authorities are still trying to stamp this out |

Never used it, but I would think it would be very easy to make your own anttenas... |

I see that reftec has a toggle switch fitted for squelch wonder if it was a standard fitting The one I have is a red push button for squelch. PCBs inside look like homebrew construction! and very platicky on the front in fact the panel on mine is broken the rig works fine though. also got 4 working Delta1s, a smart NPR934 kestrel and a handheld JTI with charger which needs restoring badly!
