GHD keys are made by Toshihiko Ujiie (JA7GHD) in Sendai City, Japan and are still
being produced. They are of a very high quality and the range covers both straight
and paddle keys. We do not have any available for sale at the moment, the details
below are for reference only.
Weighing a massive 3.5 lb (1560g) model GT501A has micrometric contact adjustment,
machined ceramic contact insert, aircraft quality bearings, and a massive lever with
two tapped holes for the knob, allowing for a half inch difference in lever length.
The positive, silky action of this key is almost beyond belief!
This key offers all of the features of the GT501A with the lever bent down to within
3mm of the base at closure. Overall the lever is a little bit longer so there is
a slight increase in leverage and mass. The knob is specially designed for comfortable
"disk grip" sending.
Model GT502 is virtually identical to the GT501A, on a smaller base and with two
mounting positions for the knob. The base measures 5x3-1/4" and it weights 2 Lb
Model GT502MIL is the "American Style" version of the 502, with bent lever. The
base measures 5x3-1/4" and it weighs 2 Lb 15 Oz. (1330g)
