Rod Blocksome’s Collins Surveys
Rod Blocksome K0DAS has been a Collins user and design engineer for Rockwell Collins for many years. Rod’s survey’s have contributed a wealth of interesting Collins information about the history of serial numbers, production numbers, design changes, and quantities built for many Collins radios. The success of Rod’s surveys are dependent on feedback from all Collins users, so if you can provide any additional information to the surveys listed below or would like to help gather and collate data for future Collins survey’s, please contact Rod at firstname.lastname@example.org.
- Scarce S/Line Units
- 32S-3A Transmitter

- 32V-1/2/3 Transmitters
- 75A-1/2/3/2A Receivers
- KWM-2/2A Transceiver

WHERE DO WE GO NEXT?
- More 75A-4 data to better define Canadian build
- Collect more data on KWM-2/2A to better define:
- missing serial number blocks
- scrambling methodology
- total production numbers
- Collect 70K-2 PTO serial numbers to clarify KWM-2/2A and S/Line units
- Need info on R-388A Receivers
- Survey other Collins models
There is still a lot more information to uncover!
