Yaesu / Standard Horizon SR-70, SR-100

I ran into these colorful, channel based radios from Yaesu / Standard Horizon. Output is 10 mW only, they do FM and AFSK/FM, and use operating frequencies that are clearly tailored to the Japanese market.

When looking at the accessory list, it seems that these radios are programmable, at least to some extent. From what I understand one channel bank is used for simplex, two other banks are pre-programmed for repeater use.

Looks like fun toys to me, when these would work in our amateur bands. No pricing available, and there’s no guarantee that these radios will ever be sold in an EU or US version.
