The first 8.33kHz-radios we bought in our club were KRT2's. After a season, we replaced them with 6201's since many club members found them to be much easier to use. The KRT2 has a comparatively complex menu structure which low-time pilots struggled with.

The Trig radio is also easy to use, but it does not highlight the active frequency like the Becker does.

The Air-Avionics radio is cheaper and even easier to use than the Becker 6201, but there's no release date yet. It's still in certification process. There's a pre-order option for EUR1.399 incl. VAT.

I find the KRT2 radio seems to give very clear transmission and reception. On my early firmware model the memory frequency input is a little buggy in that it sometimes takes a couple of goes to get digits to stick. I could send it off for an update but having got it set up there is no need.

Once you have set the relevant local frequencies in the memory I am not sure how frequency selection could be simpler. I would happily buy another - especially now that there is a new model with a colour display and a low profile version.
