Is anyone noticing that the mfsk modes are now "missing" the LOWEST tone at the start of every transmission?
?
I am not referring to the "preamble" tone (option) at 1500 Hz, and am not referring to the TXID signal.
?
At the start of every MFSK mode, after the TXID tones end, the lowest of the 16 MFSK tones is sent for about 1/5th second, to identify the lowest pitch tone.
Then the data stream begins, using all 16 MFSK tones.
?
I have been seeing this initial LOW tone on the waterfall for years with MFSK? and hearing this, but not with the newest FLDIGI 4.2.06 version. ?
The LOWEST tone is now missing.
?
However, I do hear it again on the alpha? Fldigi 4.2.06.21
Now that is strange!
?
Please pay attention and let me know if you also observe this new situation: report to ?k3euibarry@...
