Am amateur frequencies
During the '60s, pushed by the boom of mobile FM that occured twenty years earlier just after WW II, manufacturers provided at commercial purposes mobile FM transceivers but they were not really tightened up to their own channel spacing. The ionospheric conditions are called Sporadic E and Anomalous enhancement. RAC has a chart showing the frequencies available to amateurs in Canada. Some ham radio operators use the very reliable Morse code , while others use voice. Voice on the hour, Teleprinter at 15 minutes past the hour, and CW on the half hour.

My Beef with Ham Radio
Setting up a classic "Boat Anchor" rig for AM If you own one of these then you're expected to know what you're doing. I like to get on the air and have fun. Amateurs are secondary users and must yield 24 hours per day to primary government stations on the channel mostly Data and ALE. That is 60, 30, 17, and 12 m bands shall not be used for contests. When the astronauts put out a CQ call they also use Amplitude Modulation, AM The main drawback of amplitude modulation is the very low efficiency.

February 22, , This is all good information being shared here. The lists I've seen run from An KHz crystal will put you on And, on another list where possibly you could find AM operating: These FM transceivers worked not only on the 2-meter but also on the 1.
The Report and Order also allows the use of modes that comply with emission designator 2K80J2D, which includes any digital mode with a bandwidth of 2. Retrieved 17 August Several modifications to be ratified by General Conference Signals are often distorted and on the lower frequencies give a curious "watery sound" to normally propagated HF signals. Further up the band, we see segments for SSB operation and beacon operation. Narrow bandwidth mode segment with maximum bandwidth of Hz extended by 10 kHz now from 10 kHz to 10 kHz. Hope our car sticker is still doing the rounds up there!
