K3 VS 7600 Sherwood List

K3 still at top. 7600 rated #15 for dynamic range. Even an old TS-830 tops
it!

Re: K3 VS 7600 Sherwood List

Guess which radio has the best 100 kHz blocking dynamic range (146 dB),
actually 6 dB better than the K3?

...

Answer: The Drake TR-7, which was introduced over 30 years ago!

Of course, with its wide roofing filter the close-in dynamic range is
much worse and it doesn't have microprocessor control and all the bells
and whistles of a modern rig. But for raw performance, it's still
pretty hard to beat.

Have one and the R-7 RX also. Awesome old time rigs!

Besides RX dynamic range there are a lot of things by which one can
compare a good transceiver.
I am sure that many people will love the ic7600. It has some very nice
features.

Hi Tom

And who can ignore the TS830S! 30 years old and its giving the $10K IC7800
and most other modern radios a good run for their money. It can even have a bandscope WOW, amazing for a $500 dollar radio thats so old. Bye golly by gosh you will even be able to fix it, and it has all the right "numbers" on both RX and TX.

The FT102 would be another good candidate.

Now why does some entrepreneur not manufacturer the TS830S in China? Add a bandscope and a 200 watt solid state amplifier and you will have lots of change left over from $10k. ChIcom sounds like a good name!

Re: K3 VS 7600 Sherwood List

Now, if manufacturers would put their analyzers aside, and just sit down and LISTEN to those grand old rigs.... And make dsp models with the same characteristics and sound.

What a wonderful world it would be ;-)

I wouldn't mind a TS-830 replica with all dsp inside.

The small MCF (monolitic ceramic filters) used by Icom at the 7600,7700
and the 7800 at the first IF will never compete in selectivity with the
REAL roofing filters used in our K3's.That's why their dynamic range at
2Khz will never be even close.

TS-830 was the best radio ever built by Kenwood but the best feature it had was the TX speech processor which was the most efficient in its class,it made the radio sound like a KW and with a pure punchy clean audio.
