Perfect companion for the MX-S series handhelds  Time owned: 3 to 6 months
Mizuho is fairly well known for their brick SSB/CW monoband HF and 6 meter handhelds. The current series put out either 2W on HF or 1W on 6m. For each handheld there is a matching little monoband amp that boosts the HTs up to 10 watts. For example, a PL-7S matches the MX-7S 40 meter HT. For those of us who own several of these handhelds, though, a single, multiband amp makes more sense. At least for a little while the folks at Mizuho agreed, hence the PL-1000.

The PL-1000 is the same width and height as any of the other PL series amplifiers, but it's deeper. The other major differences are the bandswitch in the front and the 20W of rated output, and those differences are huge.

The amp runs on 12V DC and provides the 9V DC necessary for powering the HT, so it eliminates the need for Mizuho's little 9V power supply or DC-DC converter. The amp covers 6-80 meters. Operation with the MX-18S (17m) or MX-24S (12m) is possible in the 20m and 15m band positions respectively. The power switch has three positions: HIGH (amplifier on), OFF (powered down), or THROU (misspelled: no amplification, but power provided to the HT). The input is a pigtail on the front of the unit with a BNC connector on the end that attaches directly to the antenna connector on the HT. Output is a standard SO-239 connector on the back.

The little amp is compact, quiet, and a pleasure to operate. Mine delivers a true 20W with 2W input from my MX-7S, MX-14S, MX-18S, or MX-21S. I don't have an MX-6S, so I don't know how much I'd get out on 6m. My MX-6Z (250mW 6m HT) does not have enough output to drive the amp. It also won't work with the MX-10Z or MX-15--only with the newer series of HTs.

Of all the accessories Mizuho has made this has to be the best. Add the HTs of your choice, a 4A power supply, a CW-2S QSK/sidetone unit, and an MS-2 speaker/mic. and you turn your little handhelds into a compact, capable base station that's still quite small and portable. It's a pity these are rare items. Mizuho did a wonderful job with the PL-1000.
