The Cept Channels

Post by Buick Mackane »

Did / Does anybody use them ? Around here they were always very quiet, Makes you wonder why they bothered allocating these channels. Because by the time they were introduced the bottom had fell out the CB Boom. Was it the late 80's or early 90's they became legal ?

According to UK CB Radio Servicing ofcom advise that radios modified to cover the cept channels should be scrapped, But he removes the mod.

And the reason you couldn't legally do the mod is because the cept channels had tighter specs that 27/81 radios couldn't meet,

Anyhoo always quiet round these parts

In Poland we use only cept channels since always. I hear many UK when propagation is high.

I remember viewing one of Richards videos a few months back when he had inadvertently purchased a new President Richard. He was royally not happy with himself for not realising what it was. He ended up refusing to even modify for use on 11m, instead using it as a 10m radio in his van.

Yeah, CEPT up here Jason, as you know is very quiet. I normally only here anything when there's propagation in to Europe on FM or stateside on SSB/AM.
The only local activity I hear from time to time is a group of 3 or 4 that use CH 19 or 19A on SSB of all modes. That's about it.

I didn't know that CEPT was a tighter spec than MPT1326. I just thought that the bandwidth wasn't available to cover both when modded.

Yeah, Apparently receiver rejection is tighter and increased sensitivity. It had to meet a certain requirement to be type approved, And modded 27/81 rigs couldn't meet the spec.

Also folk put a trimmer across the reference xtal to trim the frequency, But that shifted the I.F Which resulted in it being slightly deaf,

CEPT was about 12 years too late for us in the UK.

Not that there are many people that I can hear anyway, but when I stick it on the CEPT channels, there's the off-chance that I'll hear some foreign stations now and again while I'm soldering something. Me actually switching on the radio is rare though ;)

A few of us around here use channel 1 MID on USB in the evening but apart from that I just use it for DX like many people, what with some decent stateside coming in during late afternoons on LSB.

CEPT was used for Taxi's around these parts up until very recently.

Other than that it was always pretty dead. It was too noisy for local comms due to noise from abroad, but being only FM it was next to useless for chatting back to foreign stations, apart from the odd one in Germany.

There is no such thing as a Fidelity 1000 which is too good to scrap.

Cept channels around here are used for DX but year's ago we used it for nets and I rarely ventured on to the Muppets and when I bought my Jumbo it was used on super low and super super low as well as midband and the occasional use of low band
