The HL-45B is a small compact HF and 6 meter amplifier capable of 45 Watts output on all modes. Band switching is manual, but all required low pass filters are included. Because it requires 5 Watts input to drive it to full power, detailed construction notes are provided to provide a small preamp between the Penelope and HL-45B.
Specifications and other information on the Tokyo Hy-Power labs' HL-45B are available at Tokyo Hy-Power's web site. The measured Gain of this amplifier is shown in Figure #1.
The Direct Connection Option
Phil Crosno, N6AS, did the initial work on the selection of this amplifier to provide additional power output for a HPSDR rig. His power output of a directly connected HL-45B to a Penelope/Mercury based transceiver is shown in Figure #2. Comparison of the HL-45B to the power output of the PenneyWhistle is shown in Figure #3 (using Penelope as the driver at 13.8 Volts in both cases).
The Full Output Option
David Poole, AD9DP, has developed a single transistor interface circuit that goes between the current Penelope/Mercury HPSDR components to drive the HL-45B to full power. Details on construction of this interface will be posted here as soon as testing is complete.
