The TW-100Â is a nice, but not well known shortwave transceiver. It was built by Transworld in California for government agencies and NGO’s. The set is solidly build and uses high quality components.
A while ago I’ve spent some time scanning the complete service manual of the transceiver. It should be complete and I will correct omissions or errors as far as possible.
The file is big (38MB) and contains all pages of the manual in scanned form. I have not tried to convert to text, mainly because this would be another large bit of work.
