Does anyone know if there is anything which can compare to the FT 847 for what it can do?

Also what is a good price to pay for one? I know most of you are in the USA so I will simply cut the price in half. If anyone in the UK has a 847 forsale can you let me know by Email please

Thanks charlote 2E0BSS

The only radio that compares is the Kenwood TS-2000 which is still in production.

The FT-847 does not do the 60 meter band if that's important to you.

I use one as my primary radio on phone modes and am quite happy with it.  I'm sure it's not the end-all be-all but it works well for my modest needs.

It's adequate for satellite use but if you are serious about other weak-signal modes it's not a great radio in terms of sensitivity, etc.

If you could only have one radio, it's a good choice IMHO.

Here in the US, I see them on E-bay for $1,000 or so.  Which seems about right or maybe high since they were about $1,500 new.  If you can, get one with the optional filters.  If you work CW, the narrow filter is just astonishing if you have never used a 500 hz filter before...wow.

I like mine, others have varying opinions.

Thanks for the reply, 60m isn't important my license doesn't grant me 60m (5Meg)

$1000 is around £500 seems a good price considering I found one for £800.

TS-2000 new is way out of my budget @ £1300, second hand it's also £1000 again out of my budget. Guess I'm going to have to go with the FT-450 or IC 718 or even the 897 as I like my 857D

I'm still going to hold out for the 847 if I can get one at a sensible price.

Caution:  FT897 same as FT857, same circuit boards & firmware.  You'd be buying the same radio in a different box and not get any improvements.

Go for a used TS2000.  They run circles around the FT847.

Thanks for that I never realised that the FT 847 was the same as the 857 in a different case. The TS-2000 is above my budget even used ones. Going to have to review the situation and possibly budget. If I wasn't to bothered with the 4m but wanted to keep at least the 2m alongside HF,6 & 10 what would a good compromise be? I'm thinking about the FT-450 AT

Correction FT847 is not the same as FT857.

FT817, FT857, FT897 are basically the same radio.

The FT847 (eight four seven) is NOT.

FT847 and TS2000 were "competing" radios but the TS2000 runs circles around the FT847.

Again:

FT817, FT857, FT897 are basically the same radio.

The FT847 (eight four seven) is NOT.

The ft-857 and 897 have the same curcuit board layout.  The differences are the larger case and buttons, the ability to have 2 internal batteries for portable use, or an internal power supply.

I have both and they are rugged, high quality radios that never fail.  When filtered with ssb and/or cw filters  - the rig is fairly bulletproof.  

I've used an 857 mobile for 4 years and it's a wonderful performer.  

If you can find a good 897 - it's probably the best radio you can purchase at it's price.

I have been using the 847 for several years with no problem.  Very nice radio, however the DSP is audio only while the 2000 is IF based.  Both operate in satellite mode about the same if you are interested in that, and the 60 meter mod is relatively easy,  just a diode-extomy for the 847!

Some of the early 847's did have an audio amp problem, in that the volume control either gives little audio, or room filling audio with only slight adjustment.  There is also a fairly easy mod for that.

Look around on the net and you will find much info on both rigs to help with your decision.

Although I own the 847, if the prices were comparable, I'd probably go with the Kenwood just for the improved DSP.

Quote from a comparsion between the FT-847, the TS2000 and the IC7-something or other (who cares):

"The 6 Meter comparison is still ongoing and awaiting the 50.077 beacon to be active next week. My thanks to NW5E for his assistance with a weak signal source (hi, slight pun here). My observation for the best receiver is FT-847, TS2000X then IC-756Pro for 6 meters. They all were close but the stock FT-847 did hear the best when signals were in the mud. My original thoughts and expectations for the FT-847 were low.... I assumed it would be last, but. I was pleasantly surprised it was #1. The TS2000X has a lot of really nice bells and whistles and a pleasure to operate, but this comparison was for hearing weak VHF. The IC-756Pro's main claim to fame is the band scope...a plus for contests and 6 meter activity spots. Using the beacon signal source will be needed to further validate who hears the best. I still have a feeling the TS2000X may come out ahead. Most of my 6 Meter activity has been with the IC-756Pro and I enjoy using it. The dual watch mode and band scope feature does keep the rig as my main choice as a 6 meter contest station, so far...


On 2 meters, I used the 144.285 beacon and moved my antenna so the signal was in the noise. The FT-847 and IC-275H were neck and neck for top honors. The TS2000X was excellent, but when I just could make out the CW on the two other rigs, I could NOT hear a signal on the TS2000X. This was a surprise.


On 432, the FT-847 again out preformed the TS2000X on receive using the 432.390 beacon. It was close, but my ears could copy the CW better on the FT-847."

End of quote.

So much for the TS2000 running rings around the FT-847!

I compared my new TS-2000 to my old FT-847 on 80/40/20 meters and was very surprised to find that the FT-847 receiver was more sensitive than the one in the Kenwood.  I expected the opposite, so I tried again a day later.  I disconnected the coax jumper from the Kenwood and moved it to the Yaesu, just to make sure that the jumper wasn't causing a problem.  Same result.  The Yaesu could hear better than the Kenwood.  I like the Kenwood more, but it doesn't really work any better.

I have had an FT847 for over 10 years.

The "rap" on the radio is that it has a poor receiver for HF, and that its VHF/UHF performance is pretty good.

My experience is that the HF receive is quite sensitive but the radio has quite a few birdies and other anomalies that take away from selectivity, which is probably more important.

It has an EXCELLENT pre-amp for 2M and 440 and I've found nothing better for weak signal VHF/UHF work. It will also cross-band repeat. I reiterate: for VHF/UHF, it is my best performer.

I have an FT817, 857, and an 897 as well. The 847's VHF/UHF performance is markedly better than the later Yaesu radios. that's not to say the 817-897 are slouches; the 847 is a GREAT VHF/UHF radio.

Overall, it's a great one-rig radio. You could even take it mobile. There are 4 antenna outputs so you can dedicate one to HF, one to 6m, one to 2m and one to 440.

I won't ever sell mine. I do consider sending it back to Yaesu to see what they can do about the HF birdies, but the VHF perfomance is second-to-none IMHO. I just wish I could put 1296 MHZ on it.

I replaced the stock SSB filter in my FT-847 with an INRAD 1.8Khz version and it turned the rig into a completely new, useable receiver on HF.  The stock SSB filter was too wide and I was constantly getting interference and AGC overloading from strong signals 4-5Khz away.  This completely stopped when I switched to the INRAD filter.  

Before I replaced the filter I was considering selling the 847 and upgrading.  I decided to hold on to the rig because of the improvements in receive.  I've spoken to quite a few other 847 owners who have done the filter swap for the same reason.

If you want to get a food-fight started at an AMSAT meeting, start comparing the 847 & 2000; everyone has their favorite for very valid reasons.  

If you aren't in a hurry, Icom is about to launch the IC-9100 'shack in a box' radio.  It appears to be a combination of the IC-910 (an excellent satellite righ in itself) and one of the Icom 'Pro' radios.

I'm sorry I sold my FT-847.  I had mixed reviews.  It was awesome on VHF & UHF, but not quite as good on HF.  It really depends on what you are most interested in using the radio for.  If you are looking for a great VHF/UHF rig that included HF, the FT-847 is a good choice but if you are looking for a great HF rig with VHF/UHF included, the TS-2000 would be better.  

I'm looking forward to seeing what the Icom IC-9100 has to offer, and how much it will cost.  If they take the best of the Icom IC-910h and Icom IC-746pro, it will be an awesome radio.
