The CW signal must be radiated on the center frequency. This won't make ANY difference except that you will have two memory settings for the same channel. One for SSB and data and RTTY modes, and one for CW mode which will simply occupy 10 memory slots. If the FCC engineers want to hear a 1.5 khz tone, that's THEIR problem, not ours. Maybe there will be some "simple simon" type doing any monitoring and he will have a "reference" frequency of 1500 hz. plus or minus what ever the "tolerances" are in PPM. As I said this ISN'T OUR WORRY.
Will be nice to have a "CW" place to go that will be unmolested by contesters on weekends! When is this supposed to appear in the Federal Register" anybody know? 73, Sandy W5TVW -----Original Message----- From: Mike Morrow Sent: Saturday, November 19, 2011 2:13 PM To: [email protected] Subject: [Elecraft] US 60 Meter Band Changes Approved by FCC - CW Issues I wrote: >(3) Three emission modes (CW, RTTY, Data) are authorized in addition to the > existing USB mode. There's interesting detail about carrier versus center frequency in the *new* Section 97.303: ---QUOTE--- (h) 60 m band: (1) In the 5330.5-5406.4 kHz band (60 m band), amateur stations may transmit only on the five center frequencies specified in the table below. In order to meet this requirement, control operators of stations transmitting phone, data, and RTTY emissions (emission designators 2K80J3E, 2K80J2D, and 60H0J2B, respectively) may set the carrier frequency 1.5 kHz below the center frequency as specified in the table below. For CW emissions (emission designator 150HA1A), the carrier frequency is set to the center frequency... 60M BAND FREQUENCIES (KHZ) Carrier Center 5330.5 5332.0 5346.5 5348.0 5357.0 5358.5 5371.5 5373.0 5403.5 5405.0 ---END QUOTE--- Note the *requirement*: "For CW emissions ... the carrier frequency is set to the center frequency." For example, switching from USB Phone on 5357.0 kHz to CW on the *same* channel, the transmitter must transmit on 5358.5 kHz. That will produce a 1500 Hz tone in a USB receiver set to 5357.0 kHz. It appears that now a transceiver will need to shift not only the transmitter's carrier from 5357.0 to 5358.5 kHz, but also receiver's effective frequency up by the amount needed to produce the desired sidetone when tuned to a 5358.5 kHz CW signal. The wording in the new rule seems to introduce an unfortunate and valueless complexity for CW operation.
