FT1000MP-MkV Intemodulation Audio & Video Recordings

Three equal-level signals on 7010.0, 7010.70 and 7011.60 kHz.
This mix is typical of WW contests.
Two Inrad 250 Hz CW filters.

file im-3xs9+30-ampon.mov:   signal levels S9 + 30 dB, "flat" preamp ON (IPO OFF)
file im-3xs9+20-ampoff.mov:  signal levels S9 + 20 dB, preamp OFF (IPO ON)

With preamp OFF (IPO ON) there is practically no intermodulation with signal levels up to S9 + 10 dB.

Close-in intermodulation levels like these are typical of contemporary HF receivers.
FT1000MP-MkV is probably neither significantly worse,
nor significantly better than the rest of the bunch.

Snimci intermodulacije na FT1000MP-MkV

Tri signala istog nivoa na 7010.0, 7010.70 i 7011.60 kHz.
Ovakva "mesavina" je tipicna za WW takmicenja.
Dva Inrad CW filtra po 250 Hz.

fajl im-3xs9+30-ampon.mov:   nivoi signala S9 + 30 dB, ukljucen "flat" pretpojacavac
fajl im-3xs9+20-ampoff.mov:  nivoi signala S9 + 20 dB, iskljucen pretpojacavac

Sa iskljucenim pretpojacavacem prakticno nema intermodulacije sa signalima nivoa do S9 + 10 dB.

Ovakav nivo intermodulacije sa bliskim signalima je tipican za savremene KT uredjaje.
FT1000MP-MkV verovatno nije bitno losiji, a ni bolji od ostalih.
