    Hey Fred.
    The airband allocation is 108-137 MHz… the allocation between 108 and 118 MHz is assigned to navigation and information services like VOR’s, NDB’s and ILS landing systems.
    118-137 is dedicated to voice comms and the channel spacing across Europe is 8.33.
    Hope this helps.

      Great that it'works for its price fred but I get what you are saying mate Alan from Luton 👍

    Its when you flash the moded firmware where this radio comes int its own. Use the spectrum function and you listen to the full airband at once so any transmission on any frequency you hear instantly. No scanning required. You can also reduce increase the (rf) gain so you can hear the overpowering signals perfectly. Works brilliantly.

  • @sparky71a
    @sparky71a 10 месяцев назад +8

    If you put the latest Egzumer firmware on with AM fix, it'll scan rapid,compared to what you have there. And the AM fix will mean you'll be able to hear the air transmissions properly,plus you'll be able to program your two different bands etc.

    Fred, here some help: first your sound on airband - your sound is distorted with the overhead close by planes (clearer on distant station), so pls INSTALL the Egzumer 0,21 mod firmware (it fixes AM saturation, my airband is now crystal clear, clearer than my flying radio actually). Second: don’t scan airband on “frequency scan”, you will miss 95% (or more, or all!) of the calls. Rather, make a list of the Approach, Tower, Ground, Airspace radar, SIV, etc frequencies of the airports near you and put them on memory channels (and alpha tag names, very neat on Egzumer). The SPEED of scan of memory channels is like a lightning! Very fast, you will practically listen non stop to airband calls. When you do this make a lgroup” of channels (on Egzumer you can have two scan groups) and make one let’s say “airband”, then you will scan only that very fast. In my case I have mixed airband with the 16 PMR channels, works just the same. You can make a group with any channel you’ve created. It is infinitely faster than frequency scan and besides the TWR, APP, GND frequencies are fixed, unlike CB conversations, so you can just find your local frequencies and chanalize them. Otherwise, to your curiosity the air frequencies are fitting 25khz step but since a few years already many airports and radios require the 8,33 kHz step (allows for more in between stations frequencies).
    Also, on the Egzumer you have a spectrum mode which lets you hear any peaking frequencies between two frequencies that you define (like 27,000 and 29,000mhz for example. You define from what squelch level (it’s a drawn “limbo” line that you descend or lift above the moving spectrum) the peaking frequencies will be heard. Note that other mods like “Fagci” also have spectrum mode but keep the airband distorted like on original radio. Hope you have fun with this fine firmware! I have one favor to ask but I do in a separate message. Cheers! Rosss

    Using egzumer, each allocated memory channel can be set in to a List I, List II or no list, you can do this by using a long press of key 5 whilst the memory is on the screen as you press Roman numerals on the right of the screen cycle to I, I I or both etc. Put your air channels say in I then in the sets memory 19 you can set scan List 1, List 2 or All, set to List 1 only your chosen Air Band memories will be scanned set to All the radio will scan all 200 memories conversely you can put some of your memories say CB channels in List 2 and scan just that list determined by the sets memory 19 again

    Spacing on airband is 8.33khz. But 25khz works. And what you’re listening to there is Heathrow Approach, that’s why it’s busy. Setting scan rate to 100khz you’ll miss 75% of stuff. Airband goes 118.000, 118.025, 118.050, 118.075, 118.100 etc (25khz step rate). Nowadays they use 8.33khz but you can still pick them up in 25khz spacings.

    Further to my last post, I use MMANA (web)or Dipole Calculator (play store) pop in 126.000mhz (London North Weather) and say 2mm for wire thickness. Make a home brew Dipole,with the results.I've walked around the garden with mine to find the best spot and and stuck it on the fence. Wired back to the shack,and attached to Quansheng K6. That length will scope you the whole Airband,and ain't bad on 2m!! I've now ordered some bits to make a dipole to fit directly to the Quansheng,using twin 60cm telescopics.Should be fun.

      You can lookup the service that uses any of the frequencies that broke the squelch on the web. It’s not secret information. Eg 118.825 (at 10:22) is Heathrow NW Approach. That’s why I said Heathrow Approach.

    Fred, when/if you have time, pls could you check this for me: I have a new CRT SS6900 radio. It works fine. But I have (like you) the 9900 so I got the 6900 exclusively for the CW morse mode. There I detect a problem and what I ask is to see if only my radio has this problem or all 6900. To check you will need an ordinary stereo jack cable (same small headphone stereo style jack on both sides) that will fit perfectly in the CW input on the back of your radio. Then take two crocodile clip wires (or just one ordinary wire ..) and short the base ring and the tip ring of the stereo jack that is on the other side of the cable, leave the middle ring free, it does nothing. When you short them you will hear the CW beep (this is how you can make your own DIY morse key shorting these rings). So the problem is, when I type VERY quickly three (or more) dots … the first dot is omitted, like the CW mode kicks in with a fraction of a second retard. This prevents one to type words starting with dots… if you test this do the dots very quick, and three is good number because you hear only two, if they are more you may get the impression of loosing count. It’s a simple thing but can’t explain it in a short way so thanks enormously for kind attention! If you try this pls write as a reply here. See you

The gentleman before that very kindly sent me a video trying what I asked and his test don’t seem to me as delaying the CW like mine. I have a feeling that the N models did it right but his “dots” are too slow for me to tell: one has to do three VERY quick dots and the first gets eaten if the delay is there… I just bought a secondhand President Lincoln I and when I receive it I’ll test it’s CWWM as well, I’m pretty sure it will be good… thanks a lot Fred!

    The Yeisu FT4 (basically a Beofeng in a suit) has a cool memory feature where it is possible to organise the memories into "banks" so that you can group all the PMR channels together in one bank, all the local repeaters in another bank etc. I wonder if its possible to put this feature into one of the custom firmwares, although I fully understand there isn't much memory to cram more code into.
