HELP- Very much a newbie on forums

Postby STIRLING15 » Thu Oct 12, 2017 6:44 am

I posted my first topic a couple of days ago and it was a poor effort, minus1 thankfully replied to it.
I currently have a Yupiteru MVT 7100 that i have had for many years. My problem is I have been away from scanning for several years and just recently retired. Thus now having time on my hands would like to rekindle an old hobby and aircraft scanning was part of that in both civil and military. Now we are moving to the 8.33 as a more common use thought it was time to upgrade my unit but cannot find the help that was once around. I used to deal with Lowes of Matlock but it appears they are either not around or don't have a shop anymore? I have been reading about the Icom RC-30 but this seems like it should of been released last year and there are no plans as yet for it to appear. I have also gleamed that I want a receiver and not a transceiver. Any help or advise would be greatly appreciated.

What Minus1 was saying is that very few scanners are designed to work on 8.33khz.
Think of frequency steps as being like a Bus stop. You need to stop the bus outside of Norwich Tower Number 124.250. It has several stop signs in the area & they are spaced for a certain size of vehicle.
The back of your bus may not be exactly in front of 124.250, but that is where your door should be to pick up passengers & your vehicle should fit into the bay & not obstruct other bus stops.
Scanning is like that. Currently most scanners are capable of showing 8.33khz steps, but they still have the old 25 khz filtering.
The idea of channel steps is that the band width of a transmitter or a receiver is less than the step size. As like that you only hear the frequency you want. But currently airband scanners hear the old 25 khz steps, so you are getting 3 bus stops in one.
Your Yupiteru MVT 7100 may not show 8.33khz steps, but it still has the same step size & it still has the required frequencies for existing airports.

If everyone were to write to Yaesu asking if they do a receive only version of the FTA-750L,
http://www.yaesu.co.uk/contact_us.php
the penny might drop that are missing a golden opportunity to fill a gap in the market…
I reserve the right to ignore people who have made no attempt to the read the manual, and expect others to do it for them.

Many thanks m0lsx I think I get all that and that my 7100 is still a good working unit, if I were to "upgrade " would you suggest anything?

Minus1 have just sent mail to Yaesu as you suggested awaiting their reply.

If you upgrade you in effect have three choices.
1. An airband transceiver, which you would be unwise to use, even on RX only, at the end a runway. My guess would be that you would stand a good chance of drawing unwanted attention onto you.
Scanners in the largest part are fine to use at the end of a runway. But I am not sure that airport security, the Police etc, would take the same view of a transceiver if they realised it was what you had.
2. A more modern version of what you already have. Thats a standard scanner, without 8.33khz filtering. This would give improvements, but not really improve airband coverage for you.
3. A big step up in terms of money to one of the few scanners that offers true 8.33 khz.

I believe some of the Software Defined Radios (SDR's) have adjustable filters. But SDR's are not as easy to use at the end of the runway & SDR's are not scanners, although due to the waterfall (the display of the radio spectrum on the screen) you can click on active frequencies across a reasonable spectrum with ease.
However even a £200 SDR radio like the SDRPlay2 is not good on airband without extra filtering due to broadcast stations being close by. FM broadcast near the Civil Air & DAB near Mil Air.

What is the best answer for you is dependent upon what exactly you want from your radio & how you use it.
For example at the end of the runway use 25 khz is mostly not an issue.

Thanks m0lsx that’s great info , my interest would be around aircraft civil and military for home use and runway plus anything I can pick up at distance. I think I will keep my MVT7100 for now and see if the Icom RC-30 ever appears . Thank you for your help .

I bought this SDR radio as a kit of parts to assemble yourself.
http://www.ebay.co.uk/itm/New-100KHz-1- ... SwJH1ZHT6-

It is very cheap at £16, and has room on the board to add specific notch filters if you want to, or other amps etc.
Nice solid alloy case but you do need a laptop , phone or tablet to run the software, and does take a bit of messing about to get things downloaded and set up.

It allows full coverage and I have picked up local air traffic and tower just with the very small antenna supplied from indoors. Quite easy to snap to a signal when you see it on the waterfall. Maybe one day someone will make scanning software for them?

The only drawback to this model is the VERY FINE soldering skills needed to attach two wires to the SDR dongle main IC. You need a needle sharp iron, mounted magnifying glass and a steady hand of a brain surgeon.
The whole dongle board is mounted inside of the kit board which is a very cheap way to break out the connections.

It's small size is the best benefit, as it is only the size of a fag packet, and if you have an Android phone you could have a very small and compact unit. Personally I would rather use it with a larger tablet and battery pack.
