[TenTec] IMD Measurements - Yaesu/Inrad vs Orion

[Eric SENSI]

Which is the speed needed to reach those key clicks with the keyer ???

I can hear no clicks at all into my sidetone when using my G4ZPY straight
key !

With the iambic vibroplex, I did not test it yet with the keyer.

I'm watching the enveloppe on my o'scope and it's cool... at least at slow
speed.

Thanks for answer.

Eric, ON6CV.

the real difference amount to?  (Use of the #762 reflects CW only)

ARRL:
"The real problem shows up during contests when signals
may be every 0.5 kHz (for CW) or every 2 kHz (for SSB
contests)."

Spacing         ARRL MkV        ARRL MP         RSGB MP
2 kHz           79 (+10)        71 (+2)         71 (+3)

Comparable RSGB data for Orion's 2400 Hz filter at 2 kHz spacings
is 89 dB.  RSGB did not test the optional 1800 Hz filter but
Sherwood measured 93 dB at 2 kHz.


 >Still odd, how many posts include the word "defective" when describing
the Orion, or one of it's related parts <in this case, the CW filter>.
Naaaa ... there's no QC problems ... 95% OK is just fine.  B-(

         Since the introduction of the FT-1000D in the late 80's,
what percentage of the FT-1000/D/MP/Mkv/Field have had key clicks?
And what has the manufacturer done to correct these?

Answer: 100% and NOTHING AT ALL...it's the users problem (and the
rest of us that have to listen through them all the time).

                                                 73,  Bill  W4ZV
