MX-6

The MX-6 was introduced in October, 1981 and was the very first Mizuho SSB/CW HT. All their HF and VHF Pico transceivers (HTs) are derivative of the MX-6 design. This model was replaced by the MX-6Z in August, 1982 and was never sold outside of Japan. The original MX-6 is considered quite rare.

Ouput power of the MX-6 was 250mW SSB/CW. This model had a screw in telescopic antenna and a mini phono plug for an external antenna input. While there is a headphone jack on the top of the unit there was no allowance for an external speaker/mic. The MX-6 runs on either a 9V battery or 6 AAA cells, alkaline or rechargable. An internal charging circuit was included for NiCad batteries, a feature which was dropped in the MX-6Z but reinstated in the later MX-6S.

The MX-6 also uses the 11.2735MHz IF that was reinrtoduced in the MX-6S and all the later Pico transceivers. As a result the MX-6 does use exactly the same crustals as the MX-6S, FX-6, and MX-606D transceivers. All other early 250mW Mizuho Pico transceivers, including the MX-6Z, use a 7.7975 IF and require different crystals.

If you have a manual or schematic for the MX-6 please contact the webmaster so that we may included them, as well as detailed specifications, on this page.
