Product Description



The HF Super Packer Pro 100W Amplifier is a home construction project. Are you tired on being an appliance operator? Expand your horizon. Experience the thrill of building your own equipment.

The project is a group build experience where builders sign up for the next production run. When sufficient numbers exist, the run is begun. No down payment is required to show your interest.

"I have built a lot (way more than 100) kits from many different manufacturers over the past 50 years or so, but this is definitely one of the nicest kits I have ever seen. The quality of the board, the parts, the design, and the documentation to absolutely first rate, and you are most welcome to quote me in any marketing materials you might have. This is truly a beautiful piece of work Virgil, and you are to be highly complimented on it.

HF SuperPacker Pro 100W AmpDescription This project is designed to walk you through the build process step by step. We welcome first-time builders. Let us help you be all that you can be. The project parts and your efforts will provide you with a compact linear amplifier for use with QRP SSB/CW transmitters on the amateur bands 160 through 10 meters and which can be powered from a 12 volt DC supply. The design is a good balance between output power, physical size and battery power consumption. The completed amplifier will reward the builder with a clean, more powerful output signal for a QRP rig when radio conditions become marginal.

We are building an interest list. We need many more like you to join us. You can help support this project by telling others about this amateur radio building opportunity. We do not have an advertising budget and depend upon word-of-mouth and the reputation of HF Projects providing quality projects.

All surface mount parts are pre-mounted. The copper heat sink/fan assembly is pre-drilled and tapped. You will have to put together the amplifier module assembly, the control module assembly, the case assembly and the filter module assembly.

The amplifier's conservative design uses the MRF454 type matched pair transistors. If you have thoughts of using it with a Software Defined Radio, you might want to consider including the PA-100 preamp with your order. Go from milli-watt level to 100W.

You can sign up with an email to vstamps@comcast.net. We need your call sign and delivery address. Delivery schedule based on order of payment received.

Version 4 Firmware
HF SuperPacker Pro – 100 HF SuperPacker Pro – 100W Amplifier Project: HFSP PRO 4.xx FIRMWARE. Includes programmed PIC18F2685

I decided back in February to make another run at the software for the amp. There have been new processors with additional processing power and speed that have guided my steps. The PIC16F886 is being replaced with a PIC18F2685. It is a pin for replacement. One of the biggest boosts is speed going from 4MHz to 32MHz. Another positive feature is memory (96K of flash, 3328 bytes SRAM and 1024 bytes EEPROM) compared to PIC16F886 (8K flash, 368 bytes SRAM and 256 bytes EEPROM) It also has additional 16-bit timers. One is used for frequency measurement with an improved process. The new processor has hardware multiply and a richer instruction set for implementing code. In short, the new processor is vastly superior to the current part. Macros developed and used extensively to improve code readability and organization.

The first technical problem was to cure the intermittent LCD startup behavior. Success! With higher processor speed, I have real-time clock granularity of 1ms instead of 10ms so polling of non-interrupt events can be sensed and responded much faster. The faster processor permits higher scan rate of all measured parameters with smoother results utilizing over-sampling and digital filtering techniques. I systematically re-wrote from the ground up implementing a superior structure. For instance all the IO, display and switch inputs are events that only take microseconds to respond. The algorithm is a state machine with basically 8 menus with 5 events from the shaft encoder. External events handled are CAR or PTT. My early emphasis has been on writing the core structure with emphasis on speed and organization into a state machine.

The Menus allow calibration on a per band basis. They (menus) follow about the same structure as before. They are more difficult to get detail on each screen positioned because it is now a real time system where part of the code is written as a result of an event and other code has action on a timed update basis. 1. Volts and Amps (calibration for both) 2. Degrees C and STAT (monitoring of the heat sink) 3. Power In and Power Out (calibration per band basis) 4. Power Reflected and SWR (calibration per band basis of reflected power and a SWR calculation) 5. Gain and Frequency (computations) (frequency calibration) 6. Hold Time and Mode (hold time settings for CW and SSB) Choice of SSB or CW 7. Transmit and Attenuate option (manual test on/off and attenuator options (On/Off/Auto) 8. Filter Choice and Filter Mode (auto/manual)

I will be distributing the version 4 software loaded on a chip for all the registered builders who request it.

Many man hours were devoted to improve the software. Your support is truly appreciated. Happy Operating!

I plan to also adapt this software for the Version 1 HF SuperPacker Pro 100W Amp (2006). Look for an announcement from the web site.
