 I am a long haul trucker and operate mobile/portable from any of the 48 states when I'm not at home in Columbus, TX.

Qsl direct and include my location on your card because  I do not keep a log while driving. I will send mine back to you in a few days or weeks, after I get home.

73 & gldx, Timothy   N7HLS

Readability

The R stands for "Readability". Readability is a qualitative assessment of how easy or difficult it is to correctly copy the information being sent during the transmission. In a Morse code telegraphy transmission, readability refers to how easy or difficult it is to distinguish each of the characters in the text of the message being sent; in a voice transmission, readability refers to how easy or difficult it is for each spoken word to be understood correctly. Readability is measured on a scale of 1 to 5.[1]

  1. Unreadable
  2. Barely readable, occasional words distinguishable
  3. Readable with considerable difficulty
  4. Readable with practically no difficulty
  5. Perfectly readable

Strength

  1. Faint signal, barely perceptible
  2. Very weak
  3. Weak
  4. Fair
  5. Fairly good
  6. Good
  7. Moderately strong
  8. Strong
  9. Very strong signals

Tone

  1. Sixty cycle a.c or less, very rough and broad
  2. Very rough a.c., very harsh and broad
  3. Rough a.c. tone, rectified but not filtered
  4. Rough note, some trace of filtering
  5. Filtered rectified a.c. but strongly ripple-modulated
  6. Filtered tone, definite trace of ripple modulation
  7. Near pure tone, trace of ripple modulation
  8. Near perfect tone, slight trace of modulation
  9. Perfect tone, no trace of ripple or modulation of any kind

Suffixes were historically added to indicate other signal properties, and might be sent as "599K":

  • X: stable frequency (crystal control)
  • C: "chirp" (frequency shift when keying)
  • K: key clicks
