TYT KT-7900D quad band

Postby G4RMT » Wed Oct 11, 2017 1:59 pm

This radio turned up today - got it on whim really to have a fiddle with. Up till now I have hated these dinky mobile form sets. I have a KT-8900 somewhere and it's horrible. A quick play with this quad band and I really like it. Easy to programme, and as the 220 and 350 bands hold no interest being pretty useless for FM, I have it set up with 4 things I do use. Setting channels to different spacings is easy, adding a repeater a cinch, with CTCSS, shifts and stuff simple - just tell it that you wish to go up or down in frequency, how much by, and for CTCSS, you get a list of tones frequencies - select one, press enter and it works. Simplest radio I've plugged in and got going for ages. Seems pretty sensitive too. I'll knock up a video review at some point, but it strikes me as a great cheap radio for new licencees.

It's been about for a while now, seems odd few people seem to have noticed?

I just looked them up on ebay & they say quad band, but then do not list four bands!!!

Essentially 144,220,350 and 440, and they all go up and down from the centre frequency. What I quite like is that the 4 slots that appear on power up can all cover all the bands - so you can have say, 2m in the first one, marine in the 2nd, 70cm in the third and UHF 446 or business band in the other. An old fashioned tuning knob, and a mobile friendly operating system. You hit menu on the mic, and then go up and down through the categories on the mic, or the radio knob. Press the knob to select - really nice an easy. I've not had time to fiddle more with the memory systems, but hopefully time will let me do this soon - then I'll do the video. So I'm very happy with this one - great for new hams. Bad points? Not really bad, but the size of the display with four lines of text means smallish text. That's it.

Video is up - and consists of the review and some comments about maybe not a good move to TX on the channels it came with as one is Belfast's ATIS frequency!

It's actually a nice radio, to be honest.
