While I concur fully with the Comments being filed in this proceeding by the Western States VHF-Microwave Society (WSVMS), of which I am a member, I am also filing my own comments for two reasons: 1) To discuss some of the policy implications of this proceeding in light of the dominant role ofwide-bandwidth FM repeaters in the VHF-UHF amateur bands and the technological advances in communications now occurring; and 2) To place in the record a paper I published last year that summarizes the 60-year history of amateur experimentation in the 1.25 meter band, documenting significant contri- butions to the state of the art by radio amateurs. My point, above all, is that experimentation and innovation by radio amateurs are still important--and that such activities cannot continue if the Commission abandons its 1 I have been a licensed radio amateur since 1957 and active on the 222 MHz band since the 1960s.

Digital Modes RTTY
Digital Modes RTTY Digital communication modes represent one of the fastest growing areas of interest in amateur radio, with the past decade seeing many developments. While there are other digital modes that radio amateurs are experimenting with, RTTY, AMTOR, and Packet Radio are the main digital modes on amateur radio. Newer modes such as GTOR are also emerging as amateur radio continues to develop in the area of digital communications. Baudot code is still the common denominator of digital modes, but it is far from standardised itself. While many use the term Baudot Code, others use the term Murray Code. These two names acknowledge two important telegraph pioneers, both of whom made major contributions in this field, however the correct term is CCITT International Alphabet No. 2. The differences between in practical systems is apparent in the punctuation characters and would not be noticed between two operators unless they used punctuation such as ! : % @ etc. Baudot is sent at differing speeds in different areas. Most US operation is at 45.45 baud (a hangover from a speed limitation by the FCC of 60 wpm for any coded operation), at 45 baud in Europe, while all operation in New Zealand is at 50 baud (after a collective decision to standardise to the commercial speed). Nowadays, computers have almost completely taken over from the mechanical teleprinter, so baud rate changes are no longer the problem they once were. ASCII This is used to a very small degree on amateur bands. The proliferation of personal computers in the ham shack, often with in–built communications facilities designed to work on telephone networks, encourages this mode, however there are much more practical ways to use a computer on the air.
