Interesting 70cm mobile rigs
- The Kenwood TM-455A is similar to the TM-255A but with 70cm coverage, rather than 2 meters. The TM-455A features 5 watts low and 35 watts high output.
- The Kenwood TS-811A operates from 430 to 450 MHz and is the 70 cm version of the Kenwood TS-711A.
(The TS-811B operates from 430 to 440 MHz.) BASE OR MOBILE???
- The Yaesu FT-780R is similar to the FT-480R but covers 70 cm instead of 2 meters. This version was available with either 430-439.99 MHz or 440-449.99 MHz coverage. The output power is 30 watts SSB PEP, 30 watts CW and 30 watts FM. Requires 4 amps.
432 MHz band
In some countries, the band starts at 432 MHz. In the UK, repeaters are around 433MHz, and the band is only 430-440MHz. (And in some countries, there is no allocation at all.) The 2m band is sometimes referred to as the 144MHz band, and the 3rd harmonic of that is 432MHz. I have heard the 23cm band referred to as the 1296MHz band, too - for the same reason (3rd harmonic of 432MHz and 9th harmonic of 144MHz).
