Radio Equipment : HF Transceivers : Yaesu FT-1000MP

• FT 1000MP MK V and Keyclicks - 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.

• Preventing CW key clicks - 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?
