+This project set out to develop a 2-watt single ended IPA and keying interface between a Penelope and an unmodified Tokyo Hy-Power Model HL-45B Linear Amplifier.
 Tokyo Hy-Power HL-45B: With a rated output of 45 Watts and band-switchable harmonic filtering, the HL-45B is a good complement to Penelope. The HL-45B is specified for its 45 watts out with 5 watts in, but the experience of AD9DP and N6AS has been somewhat better than that – one can get by through 10m with about a watt, and certainly less than two watts.

 both primary and secondary of T2 in a 3:2 ratio. The wire type is noncritical but larger diameter is preferable.
 With a little patience on the last turn, it is possible to thread 5 turns of 20 gauge hookup wire with .050”

-The plot shows that power gain falls with increasing frequency between 7 and 28 Mhz. It is lower at 3.5 MHz due to transformer limitations and is only 6 to 7dB at 50MHz, which is beyond the specifications of the NTE235. The IPA nonetheless realized 0.5 watt out with the maximum 150mW available from a Penelope (into its 1.7:1 VSWR.) This was sufficient to obtain 30W from a HL-45B in the 6m band.
+The plot shows that power gain falls with increasing frequency between 7 and 28 Mhz. It is lower at 3.5 MHz due to transformer limitations and is only 6 to 7dB at 50MHz, which is beyond the specifications of the NTE235. The IPA nonetheless realized 0.5 watt out with the maximum 150mW indicated by Penelope (actually something less into the 1.7:1 VSWR.) This was sufficient to obtain 30W from a HL-45B in the 6m band.
 The plot also shows 2 to 4db of gain compression between 1 and 2 watts power output as the NTE235 runs out of collector swing. Up to 1 watt however, the gain was as flat as the available instruments could measure. The chart is no better than ±1db in the absolute because of instrument limitations, and as always in Amateur Radio, YRMV.
