Important Safety Note: Working on or testing equipment such as the Heathkit HW-101 transceiver and the HP-23 power supply is extremely dangerous since very high voltages are present when the equipment is turned on, and may even be present when the equipment is turned off and unplugged. If at all possible, do all work with the equipment off and unpluggedand be sure that the capacitors are properly discharged before working on the equipment. The operator assumes all risk and liability in such matters! Do not work on this type of equipment unless you are experienced with working around very high voltages!

There is nothing more important in restoring and operating a piece of equipment than having a copy of the operating manual. The operating manual can give important operating information that will allow the owner to get the most out of the equipment, and it is next to impossible to repair and restore a piece of equipment without the schematic diagram which is also contained in the manual..

I hunted through the web to obtain the files below. I am not the one who originally scanned the documents in .PDF format. I frankly do not remember where I found them, and therefore express my thanks to those who did scan them and my apologies that I was not able to give credit to those that so generously made them available.

Besides the manual and schematic diagram, it is always nice to see advertisements and modifications for a piece of gear that one owns. The ads help place the gear in its proper perspective and show how it fits into the grand scheme of things. Below you will find advertisements for the HW-101 that appeared in Ham Radio and Practical Wireless in the 1970s.

I hope you will find the files below useful in restoring, operating, and enjoying your HW-101
73 and see you on the air,
