[Icom] QSK w/756Pro??

Wed, 03 Jul 2002 20:12:21 -0700

Hi Dave,

...to say nothing of the receiver birdies produced by the Omni's rather
peculiar frequency-generation scheme. I would love to poke around inside
that radio with an RF probe connected to my HP spectrum analyser.

Cheers for now, 73,
Adam

Hi Everyone,

I purchased my Pro II at Dayton.  Since then it has caused me to sell my
Omni VI after six years and in spite  of a complete retrofit of aftermarket
filters and several major mods that I performed on it.

Though this will be considered blasphemy by the Ten Tec Loyal, the Pro II
has vastly better QSK than the Omni VI which exhibits a nasty sidetone
click, and receiver thumps and whooses on each changeover. QSK on the Omni
VI was miserable. It also could not be much improved.

The Pro II is on of the best QSK rigs from Japan I have used. Not perfect
(as is nearly achieved with my remaining Omni V) but nearly so.

I also use an outboard keyer on all my rigs, the Idiom Press CMOS-4, a great
unit.  It removes the leading character truncation caused by the rig's 10 ms
relay delay. The CMOS-4 has a "k" compensation factor to match this kind of
delay on many different rigs.  I use an 8 ms compensation factor on the Pro
II.  Check it out at http://www.idiompress.com/cmos4.html

My $.02

I could also tell you about my adventures with the Omni VI's CPU chip
induced receiver  birdies but alas that is best left for another day.
