Default What is the best HF transceiver these days?

Hello,

I've been out of the hobby for years now, but want to purchase an HF
rig, possibly with the 6m and 2m and even 70cm options. My main
concern is that the radio have the best and most flexible receiver
possible. I'd like to do some DSP work and if the receiver is a
software receiver and is programmable, that would be very desirable.

I was looking at the TenTec site and they advertise a transceiver with
0.35 uV sensitivity at 10db S+N/N in a 3KHz SSB mode. On the other
hand, the Kenwood 480 guys are claiming a 0.10 uV sensitivity, but
didn't say what mode.

It looks to me like TenTec is the most technologically advanced, but
then why the lower sensitivity? I wonder if Kenwood is not completely
truthful.

Well anyway, what's going on? Are these the right brands to be
looking at anyway?

Thank you,

StevenS

BPL will be ending Ham Radio soon.

Save your $$$$.

I think you can't go wrong with any of the major makers such as TenTec,
Yaesu, Icom, and Kenwood. They are all good. In either case, the
sensitivity is excellent and you as the operator probably won't notice the
difference. Your antenna setup will make the major difference.

Instead, decide what features you want and how important each feature is to
you. Then see how the various radios stack up. For example both my
husband's Icom 741 and my Kenwood TS-2000 have built in keyers on which you
can set the speed. However on his there is no readout as to what the speed
is. You have to just set it by ear to the approximate speed that you want
but within its range it is infinitely variable (i.e. not limited to whole
number increments). On mine, I get a readout of the setting and can set it
at a specific speed. but it is limited to whole number increments. So what
do you prefer? His radio allows the add-on filters internally as well as
having DSP. Mine does not. Again what is important to you?

I would not concern thyself with BPL too much.....
they have got enough problems of their own.

Are you looking at the software defined radio angle?
There are a couple of those now being manufactured that
might be better platforms for doing DSP work.

Ya .... right.

Check out www.eham.com ... look at the equipment reviews section.

Firstly, Ham Radio is not a hobby, it's a technical pursuit.

The best transceiver for any self-respecting _REAL_ Radio Ham is
the one that he conceives and makes for himself.

CBers, OTOH, have a hobby and buy their rigs off the shelf, even
sending them back to the emporium if needing repair.

You'd be surprised at how many CBers-Masquerading-As-Radio-Hams
there are to be found today!

Looking at sensitivity without examining the other receiver characteristics
won't tell you much.
You should take into account all of these:
Sensitivity
Dynamic range
Selectivity -- Filter Characteristics such as Shape factor (skirt
selectivity) and ripple
Intermodulation Distortion
Phase Noise - Noise floor
Minimum Discernable Signal
DSP performance
More

See Selecting a rig at URL:
http://www.arrl.org/tis/info/pdf/29379.pdf

Then read the reviews

The ARRL transceiver reviews is a good place to compare these specs and what
they mean.
http://www.arrl.org/members-only/prodrev/

A rig can have super sensitivity specs with lousy dynamic range -- it is
difficult to get both -- lots of tradeoffs in receiver design.
Dynamic range is a very important receiver spec as is selectivity as well as
sensitivity.

Look for high receiver intercept points, excellent dynamic range, sharp
selectivity and a low phase-noise synthesizer

Be careful when comparing a $1000 radio to a $3300 radio -- there are
usually good reasons for the higher price.
