Following is a section on Frequency Modulated Amateur Television.
Some of the links are to articles which I (WB9OQM) had written and were published in Amateur Television Quarterly (ATVQ) back in the 1990's, and a couple in 'QST' back in the 1970's.

'Comments on Commercial FM TV Standards as Applied to Amateur Operations' which appeared in ATVQ - Winter 1994 and

'Calibrate Your FM TV Receiver to Measure Video Deviation' which appeared in ATVQ - Spring 1994.

Also, here is a letter 'More on Video Preemphasis and Deviation Calibration' which I had written to Bill Parker (W8DMR) concerning an article of his which was published in ATVQ - Fall 1998.

'Low Frequency Test Tone FM TV Deviation Calibration' and a note on intermodulation.

'Estimate the Audio Deviation on a RF Subcarrier' Using an oscilloscope

'Calculate AB Amplifier Operating Parameters' for making Linear Power Amplifier adjustments for better linearity and efficiency.

Also, see 'QST' of October 1974 , 'Hints and Kinks' column for an article on using spent shotgun shells for plug-in coil forms.

Another 'QST' article, in the February 1977 issue, is 'Inexpensive Traps for Wire Antennas'. This article describes a pioneering use of coaxal cable in place of high voltage capacitors. This article has been a reference in the 'ARRL Antenna Book' for many years.

Volunteer Wanted: Someone in Geneva, Switzerland who can who can go to the International Telecommunication Union library and get the references from the original 'CCIR Recomendation 405'. The current 'CCIR Recomendation 405-1' does not carry those references.
