UBC3500XLT

[millsey]

Hi Guys,

Although a newbie here, I have been listening on Airband for many years. I have a home brew synthesised Rx's dating from my Days at Ambit International in the 70's which still works very well. Based here in Chelmsford I am able to hear EGSS very well and also EGLL director and approach on 119.725 and 120.40 using a high outside antenna.

I recently purchased an Eton Satellit 750 to further enhance my listening and it's cr*p. Problem is simply that you cannot change the B/W in Airband mode to wide, and the narrow bandwidth is too narrow (7KHz ??) As you perhaps know, many channels in the London area are using a Tx offset. For example 118.825 hears the A/C but I have to retune to 118.830 to hear LATC's side of the transmission. Then you miss the A/C again !

I want to buy a UBC3500XLT and suspect this will be fine, as is an IC-R5 that I currently also have - but try as I might I cannot find any bandwidth figures given in the Uniden data. So hopefully you guys can put my mind at rest and confirm that you all hear both sides of the conversation.

I'm also playing with SDR Airband radios and this shows the offset Tx frequencies easily on the waterfall display..

I use a 3500 and have no issues. Go for it dude!

...and welcome to T1

Yeah i use a 3500 too and works great for me on airband.

The UBC3500XLT only has one AM bandwidth, and it's 25 kHz. I'm not aware of any commercially available scanners that do 8.33 kHz channelling properly. You just have to put up with the compromise.

iv got a icom ic-r3 scanner i want to swap for a ubc 3500 if anyones interested

ic-r3 covers everything up to 2.6ghz and has a built in lcd tv

Ive got the UBC 3500 too and it works very well for me too - give it a shot

The 3500xlt does do 8.33

It 'does' 8.33 in the sense that you can tune in 8.33 steps and key in 8.33 frequencies.

But it does NOT 'do' 8.33 kHz bandwidth. It only has one AM bandwidth, 25 kHz.

So if you tune to an 8.33 freq that has 8.33 channels on adjacent frequencies, you will hear all three channels.

Fortunately there aren't many examples of such adjacent 8.33 channels.
