Currently available Mizuho QRP gears …

We are not related MIZUHO company at all. These are currently available MIZUHO QRP products list with my comments here just as an information to foreign QRP friends. You can purchase them 10-15% off at amateur radio retailers in Tokyo ($1=YEN125.)

Transceiver
(We call them Pico series)
Model Price Freq. Mode Pout
MX-6S 32,000yen 50MHz SSB/CW 1W
MX-7S 32,000yen 7MHz SSB/CW 2W
MX-21S 32,000yen 21MHz SSB/CW 2W
PL-6S 21,600yen 50MHz Linear 10W
PL-7S 21,600yen 7MHz Linear 10W
PL-21S 21,600yen 21MHz Linear 10W

Comments: The smallest CW/SSB transceiver in the world. S/RF meter, Noise-branker, Attenuator installed handy talky type QRP rig. VXO A/B channel selection of each 50 kHz (below 7 MHz:25 kHz) coverage. IF is 11MHz.11Tr 3IC. The company sporadically make 3.5,14,18,28MHz version. It is very difficult to buy them because many amateur want to have it. Now only completed Pico transceiver is supplied. I suppose many failed to complete kit and troubled company.

 

Options for Pico:

Type Price Definition
PM1 3,300yen DC-DC converter
MS-1 4,600yen SpeakerMic
PR3-S 4,500yen Lack mount (MX,CW-2S,PL)
CW-2S 8,400yen CW semi-break-in unit /w sidetone
BM-6 1,500yen lather bag
PS-2 3,600yen AC adapter
Crystal 1,800yen any desired 25/50Khz band
PAN-62 5,200yen pocket dipole 50/144
AN-50 3,600yen 50MHz lod antenna
AN-7 4,800yen 7MHz lod antenna
AN-21 4,800yen 21MHz lod antenna

 

Comments: Pico need 9V power (AAA battery x 6). Feeding 12V will destroy the unit. I think the DC-DC is expensive you can make 9V with 7808 and one Di between the GND. CW-2S is recommended for CW operation.

 

Kits and misc.:

Type Price Definition
QP-21 3,000yen 21MHz, 1W, CW, transmitter
QP-7 3,000yen 7MHz, 1W, CW, transmitter
CK-1D 9,000yen Currtis Electric keyer
VFO-5D 6,000yen stable 5-5.5M VFO module
VFO-5D 6,000yen stable 7-7.1M VFO module
MA-1 1,300yen audio amp module
MA-20A 2,000yen Mic amp module
PF-1A 2,500yen CW peak filter module
KX-50K 8,000yen 50MHz antenna coupler

Comments: QP series are the most famous kit with fixed crystal. It does not change the price more than 10 years. The VFOs are sealed module with iron case.Japanese QRPer use this unit to avoid difficult unstable VFO problem which annoys other station.

"MIZUHO" means beautiful riceplant. The owner JA1AMH Mr.Takada named his company as he wish everyone to remember the beautiful country and free quiet life with his QRP radio goods in this busy world.

I am no relation with MIZUHO. Just a user enjoy MIZUHO.
