You're welcome - that is a LiveATC supported feed.

Thanks for the new RJAA feed and the RJTT feed !! Great coverage.

Just wondering about 121.650 (Clearance Delivery #1) on the RJAA feed, I know it's a published Clearance Delivery frequency, but checking some random archives it does not appear to be in use ? Anyone know if they ever actually use this frequency ? If not, any chance this radio/dongle could be used for maybe a more active frequency ? Maybe Tokyo control on 133.60 ?

Speaking of Tokyo Control, the RJTT feed covering Tokyo Control is excellent, very good controller and aircraft reception on 120.50, it's just this frequency is extremely busy and the feed tends to get overloaded and blocked with the other Control frequencies on there. Now that 125.90 is covered on the RJAA radio would it help if 125.90 was removed from the RJTT feed to help with congestion ?

Ideally 120.50 would be great as a stand alone frequency on the RJTT feed and another radio/dongle added for 133.70/123.70. If that is at all feasible on either feed I would be happy to donate to help out. With just a few more additions you could have all the Tokyo Control frequencies covered in that area too. Tokyo Control sector chart attached below for reference.

We're kind of maxed out at Narita. The only way we are able to have as many channels there as we do is due to the ability of the SDR and software to provide multiple feeds when the frequencies are close enough. For each SDR we currently have a 2.5 MHz window. So it becomes a tradeoff.

In this case, getting rid of Clearance Delivery would not buy us anything since that SDR is already in use for other important channels.

At Narita we are also on the edge of being able to pick up Tokyo Control. The RJTT receiver is closer to those transmitters.

We do have one slot to try 120.5 - not sure what the reception will be like but we'll test it. Not sure we should make any changes at RJTT, though....even though there is some congestion the reception on that radio will be better.

dave,

Thanks for the info.

Will be interesting to see what it sounds like, it's a very busy and interesting sector. Anyone know if you can hear the controller's from the RJAA area on some of the other Tokyo Control frequencies close by ? 133.600, 132.250, 120.975, 128.200, 124.100 and the backup frequency 134.00 ? I'd be willing to donate the funds for an old fashion scanner to cover these frequencies, even without controller reception, if anyone can accommodate it ?

I was just thinking about 125.90 as you got it covered at RJAA, but it is the night primary frequency, so maybe better to leave it on RJTT with the others ? Was kinda hoping maybe some frequencies could be split off to dedicated feeds there, or there is someone else in the area that could provide another feed ? Like I say I'd be willing to donate to get more SDR's or scanners there, but totally understand if it's not possible.

Thanks for the great work !
