The Tokyo Hy-Power HT 750 is a great
portable SSB/CW rig for the 40,15 and 6 meter bands. It weighs in at 1.5
lb. with the 8 AA batteries inside. Additional jacks are provided for a
speaker mic, key, and 12v dc. There is a pre amp switch located on the
bottom as well as a charge selector ( if NiCDs are used ). Controls consist
of PTT, RIT, Audio/on-off, Tuning, Step rate select, Frequency lock,
and Noise Blanker. Size is 2.7"w x 7.5"h x 1.8"d. The radio outputs a maximum
of 3 watts on 40 and 15m, and 2 watts on 6m. Included is also a 12v dc
cord for power or charging. Options include a leather case, external hand
speaker mic and a 4 ft. whip antenna with coils for each band.
The HT 750 has a very good front end and receives well. Even with the whip antenna RX is good, though if an external antenna is used usually the RX pre amp needs to be turned off. TX with the stock whip antenna/loading coils is of course poor. Not to say it can't be done as I've worked Italy on 15m with the 4 ft whip, It just makes the contacts real hard. When hooked to a proper antenna, the HT 750 works as well as any other QRP radio I've own... Mostly, if you can hear them, you can work them and that's all I'm really looking for.
This rig is my all round hiking/backpack radio. It's not the smallest
QRP rig I own, but it covers 2 popular HF bands in both SSB and CW and
not many radios do this in this size. The dual bands ( plus 6m )
allow for contacts in varying conditions. I also like the fact it can use
AAs, as these batteries are usually available regardless of location.
My HT 750 is packed in a weather proof lunch bag along with my ZM-2
tuner, a small straight key, mic, fishing line and 22g wire in lengths
of 33, 66, 85 ft.( also of course, an extra set of AAs ). My antenna used
is a long wire pulled into the highest location around ( and I can connect
the lengths in any combination ).
Sadly, at this time the radio is out of stock with Tokyo HyPower. The company predicts another run of production but was unable to give a better time frame than during the year (mid 2000).
These photos taken at Sunken Meadow State Park, NY. Great view of LI Sound from the tables on the Boardwalk. Trees on the side allow for an end feed wire. (The ZM-2 tuner handles both wire and coax) The small straight key comes from an unknown maker in Africa, it has a cover for a leg strap if needed. The paddle is from White Rook and contains a Tick chip. The small travel pack carries all the equipment needed for an outing. For longer outings, I pack the Poqet PC for logging and a small 4aHr battery.
