How to correct keyclick problem in ft1000 and ft1000d radios.

Clicks are most problematic when we try to copy weak signals next to moderately strong signals. How to recognize them, and how to identify clicks problems

The Necessary Bandwidth for CW Signals By George Grammer W1DF

Key clicks are generally undesired clicks or thumps generated by a CW transmitter as the key is put down or let up. How much does the rise time or bandwidth of a CW signal need to be limited to prevent other QSOs on adjacent frequencies from being annoyed by key clicks?

The CAT (Computer Aided Transceiver) System in the FT-950 transceiver provides control of frequency, VFO, memory, and other settings such as dual-channel memo- ries and diversity reception using an external personal computer. This allows multiple control operations to be fully automated as single mouse clicks or keystroke op- erations on the computer keyboard.

YaesuFT1000MK V stands out with improved close-spaced SSB transmit performance, reversing a trend seen in other modern radios. Featuring a class-A mode, it offers clean HV finals when kept out of ALC. However, two significant flaws persist: the noise blanker causes receiver IM distortion, and the transmitter lacks wave-shaping on CW, resulting in pronounced keyclicks. Preliminary tests reveal strong keyclicks +1kHz and -1kHz, prompting a combined modification to address both issues.
