Airband frequencies

[Neil Springate]

Hi All,

I've just bought a Yupiteru MVT-7100 and have been advised that the preset
bands are not suitable for the uk, e.g. we need 12.5k steps for the airband.
As I am a newbie, could you tell me what I should set the airband to in
terms of frequency range, step size and mode (fm, am, wfm, usb, lsb, etc)?
Any other bands of interest? Marine perhaps? PMR? The receiver has a range
of 100kHz to 1.6GHz.

Also, is there a good reference work of frequencies online anywhere? Again,
being a bit thick, I would need to know the step size and mode for the
frequencies/bands

Hope you can help,

Neil.

Airband is normally 25kHz spacing, however you will need to select a
smaller step for some ATC frequencies because the ground stations often
transmit around 5KHz high or low of the nominal frequency, this is known
as offset frequencies, also 8.33 step channels are gradually creeping
in, for these frequencies you will need to select 1KHz steps. The VHF
airband is 108 - 136.975 MHz (voice communication is generally on
118 -136.975) AM. The military UHF airband is 225 - approx. 400 MHz AM
(25 KHz spacing). There are no 12.5 KHz spaced frequencies in the
airband.
There are also airport repeaters in the band 455.475 - 455.975 MHz,
NBFM, 12.5 KHz channel spacing.
Aircraft using HF will be between 2 & 30 MHz, USB.
Ship to shore channels are 156 - 163.4 MHz, 25 KHz channels spacing,
NBFM with a lot of traffic on channel 12 (Mersey Radio), 156.6 & channel
16 (calling channel), 156.8 where I live (nr Wrexham, North Wales).
For PMR stations, do a search 160 - 220 MHz, 12.5 KHz steps, NBFM.

Many thanks Mike,

That's certainly enough to get me going!

A little clarification needed here.

Chan 16 - Marine calling and public distress channel - 156.800MHz
Also try Chan 0 on 156.000MHz which is the Coastguard/RNLI/Helicopter
private channel.
You will find marine frequencies at
http://www.yachtcom.co.uk/comms/vhfchannels.htm

PMR will be found at 165-168.5MHz
Trunked on 178-182MHz and 201-206MHz with 12.5KHz spacing.
You will also find PMR at 85-87.5MHz and around 453-454 and 456-458MHz
UHF and most VHF are NBFM but you may still find some AM

These PMR are all base frequencies - you will have difficulty
receiving mobiles directly.

Amateur is on 70-70.5MHz, 144-146MHz, and 430-440MHz with a mixture of
FM, SSB, CW and some AM.

I suppose that being a radio ham myself I should have mentioned Amateur
Bands.
Now I must try and figure out all about this 6 metre thingy :-o)

Plus try 28-29.5, 50-52 and 1240-1325 for amateur. CB on 26.965-28. Some
military elsewhere but depends on area (in my area ground crews are in the
410 area). There are other things to be found, but just to get you
started...

[PromaBoss]

raf bases use 408-410 usafe and others still have some in 410-425 although
this was supposed to be closed for dolphin tetra to use[now defunct],some
old users never moved off

also 429-439.9875 extensively used by army/again USAF and MOD sites,other
gov users alos here hams are secondary users

443.5-445.5 also MOD used

Once again, many thanks for the responses. They have all been collated
and all the info will be entered, once I've worked out how to do it!

At least the MVT-7100 is very easy to use & set up.
The nicads that came with mine were crap with one cell permanently dying
after a years use, so I stuck 4 x 1300 mAH NiMH batteries in that I got
cheap at a supermarket, much better, although it's advisable to get them
out & clean the contacts from time to time.

Hi Mike,

I was wondering about the batteries - do you think it is safe to
recharge NiMH using the 7100's in built charger? Or would that be set up
specifically for NiCd? I've got a pile of 2300mAh NiMh's and have been
charging them with an external charger.

Cheers,

Neil.
