WOW! That's all I can say. This new Airband Receiver from AOR is top-flight and I want one! But sadly I can't have one - yet. The AR-7400 was unveiled at the Tokyo HamFest in 2019 but the Corona Virus has obviously put paid to a 2020 launch.
Hopefully, the Japanese manufacturer will soon be able to provide us with an expected delivery date in the UK and I've got my name on one already.
This stunning new scanner appears to be set in an AR-DV1 case and shares all the DV1's buttons and dials. The screen is split into 4 readouts, showing the frequency (and other information) of each of the receivers 4 VFOs. Both Civil and Military bands are covered (plus they've thrown in the Broadcast band).
Apparently, the receiver can scan the entire civil-airband in less than 1 second!!! Now that's fast by anyone's standards. As you can see in the photo, it has an SDCARD slot and a record button just like the DV-1.
I have no idea, but I'm kinda hoping that you can program the scanner to record a particular VFO when the squelch is broken. That would be handy for monitoring the emergency channel and recording any event that occurs even when you're not within ear shot.
Being able to monitor 4 separate channels at the same time is a real boon and on the back of the receiver you'll find 4 sockets for 4 separate speakers - one per VFO (obviously). It also has a line-out. The only negative I can see about this airband scanner is the fact that it only has one antenna socket (BNC) 😓
No prices have been announced or even hinted at, but I'm guessing that it's gonna be pretty damned expensive.
Coverage: VHF band 108 ~ 137MHz (AM), UHF band 225 ~ 400MHz (AM), WFM 76 ~ 108MHz;<
IF Bandwidth : AM mode 6kHz (5.5kHz);
Reception: VHF / UHF 4-wave simultaneous reception;Speed: Ultra-high-speed 1-second scan / search. Example: The time required to scan the range of 108 ~ 137MHz is about 1 second (when the signal on all channels was not out).
Antenna Connector: 1 x BNC (Female);
Speaker: 1 x top mounted internal (assumed based on image) AND 4 x 3.5mm rear speaker output jacks
Other: 1 x Micro USB (front) 1 x Line 3.5mm jack (rear), 1 x SD/SDHC card reader (front), 1 x Auxiliary socket (rear) (assumed based on image).
UPDATE 1: I heard from someone on FaceBook (Rick King) that AOR have been having issues with harmonics and the SDR chip and that's contributed to the delays too. Rick further commented that he felt the 10 character alpha-tag restriction was a let-down. Personally it wouldn't bother me too much because I'd be using tags such as EGCC-TWR1 but I suppose longer tags would be helpful. The small screen comes in for some criticism too.
