Hello, I'm looking for a small'ish portable HF rig and it's come down to the FT-857 or the IC7000 I know the 7000 is twice the price ! is it really worth that much more ?? ideas please - this will be my first foray into HF TX as well !!

I would look for a closeout IC706MKIIG. But I am partial to that rig because I own two of them. The 857 is a nice radio for the money.

If it were me, I'd lean more towards the IC-7000 or, the close out of the IC-706MKIIG.

Why? Easier on the eyes (at least mine Grin) in terms of the display. All the push buttons are right in front of you as opposed to the FT-857. Any one of the three radios here are good if you just want to hit the power button and operate on the fly. I've played around with all three radios side by side comparison before I settled with the MKIIG as a mobile. The sub menus on the MKIIG and IC-7000 were less of a pain than the FT-857 IMHO. That's just me. YMMV.

HF TX mobile you say? I'll let Alan fill you in on the wiring, bonding, and the caveats of operating HF mobile. Good luck with you install.

The FT857 is getting rather long in tooth, as is the IC706MkIIg. Both use audio DSP which is fine, but isn't nearly as effective as the IF based on in the 7000.

Most of the menu items in the 7000 are set, and forget. The only difficult procedure is programming the memories. You sure wouldn't want to do that while under way. There are apps which allow you to program the whole radio via the CI-V data port.

Said data port can also be used to control a fully automatic antenna controller. The other two are far less capable in this respect.

The most important part is the antenna, and far too often that is a scrimped-on item.

I've got an FT-857D, and have grown to like it very much.
The menus are kind of a pain at first, but you get used to it.

I looked at the IC-7000 before making my decision. Nice radio.
And IF DSP will be more effective than audio DSP. No doubt about that.
The 7000 has lots of cool features the 857 doesn't have. But reports
of it having overheating problems worried me. And it's rather pricey.

The only thing I see really wrong with the 857D, is that it does not
do full break-in keying on CW. I operate CW quite a bit, and the lack
of full break-in really took some work to get used to. But the size,
capabilities, and power requirements, along with the much lower
price tag caused me to decide to purchase the 857D.

Obviously, your mileage may vary. Do your shopping, do your
research based on what YOU think is important, then make your
choice, get on the air and have fun. That's really the most
important part.

PS - Hamvention is coming up. A great oppurtunity to see
everything under one roof, in one place. It's a good time, too.
Highly recommended!

I'm always amazed when someone reports a heat problem with any modern transceiver. Darn right they get hot! About half the input power goes up in heat. It is especially evident in miniature transceivers. I suspect that's why the unknowing install extra fans to keep the heat sink cooler. It is as if the amateur community knows more than the designer of the transceiver in question. And, once posted on some blog, suddenly the non issue, becomes de rigueur problem. Hogwash!

People who have heat related issues, never think about how, and where they mount their transceivers. Sticking them into cubby holes, or hiding them in center consoles, is an obvious faux pas. What needs to be done, it to mount them as clear as possible, using the factory suppled mounting brackets so the air can flow all around the transceiver.

As for the Hamvention... I suspect, based on the past few years, the IC-7000 will sell for ≈$1,099.

I was tempted by the 7000 as well, and came to the conclusion that it wasn't $600 better.

I liked the fact that the 857d draws less juice. I can operate for hours on a 12 volt, 7 amp  $40 motorcycle battery from my backpack.

It's also smaller, so it fits in tighter places in the dash. I'm realizing now that I will eventually get several radios, but the 857d is a proven performer, and a good starter radio for a new ham, that won't break the bank.

I've got about 3 months on mine, and my license, lots of fun so far.

If for some reason you DO get a MkIIg, whatever you do,
no matter how good of a bargain it is, no matter how "mint"
it looks on the outside, BE VERY SURE THAT THE SERIAL NUMBERS
START with 150xxxx and NOT 012xxxx
.

The MkIIG's that start with "012xxxx" Serial Numbers
use the notoriously failure prone and absolutely UNOBTANIUM
PA Transistors. To make matters WORSE (if possible) even the
PA boards WITHOUT the PA's for those serial numbers are UNOBTANIUM.
Can't be found. Nada, zip, zilch. Anyone with half a brain who had has owned
a 120xxxx MkIIG that died (of some other reason than PA) has already
parted out the PA Board for at least $400.

There is a Tech in the Midwest who will MODIFY a "newer" PA
board to fit the "012xxxx", but he charges $500 JUST FOR THE
BOARD MOD. It is NOT a job for the faint f heart, but for the foolhardy.
That $500 is BEFORE any other needed parts  & work! (The "150xxxx" MkIIG PA Board,
IF YOU CAN FIND ONE, is about $600 from Icom.)

And of course this is assuming that there is NOTHING ELSE at
all wrong with the rig

All of the transceivers mentioned here output a nominal 100 watts. In order to do that, the input power to the finals must be about 200 watts. Plus, you have driver current, fan current, etc. And, all three transceivers mentioned here draw a max of 22 amps at 13.8 volts. Concluding that the FT847 draws less power, is an incorrect assumption.

I also agree with the 706MkIIg problem, but I'll add this. Currently, the only way you can repair a late model 706MkIIg is to replace the complete PA board; the final is not available by itself as mentioned above. If you believe the scuttlebutt, even those are getting rare. Speaking only for myself, I wouldn't touch a brand new, still in the box, 706MkIIg for the reasons stated.

Basically, the same issue affects the FT857, albeit PA boards are still available. For how long is the real question.

Also, the 857d covers HF and vhf, so you don't need a separate 2 meter radio.

So does the IC-7000. Fact is, it runs nearly double the 2 meter, and 440 output than the 857.

FT-857d - 100w @ HF-6m / 50w @ 2m / 20w @ 70cm - 22A current at full TX
IC-7000 - 100w @ HF-6m / 50w @ 2m / 35w @ 70cm  - 22A current at full TX

Alan, how is that double the 2 meter and 440 output power?

Kenwood TS480:
  • Doesn't suffer from lower TX power output when you turn the engine off
  • All the functions you want to use are on buttons on the front panel - you don't need a stupid "quick guide" manual to figure out where the menu to change the mic gain, power, NB level etc is
  • It has a display you can actually see in direct sunlight
  • The "Face Off" kit is included with the radio as standard
  • The speaker is built into the front panel
  • It doesn't use proprietary leads. You can make up a separation cable with a crimp tool and some spare CAT6 network cable.
  • All the buttons are backlit
  • All the menu entries are in plain English
  • It has no known issues.
  • Still in production.
  • FAR BETTER HF PERFORMANCE THAN BOTH OF THE OTHERS
  • Excellent second hand buy.

Run 13.8 volts to the back of both, and measure the power into a dummy load.
