I have owned a ft-840 for almost 6 years and It's a good radio and will run fine on am. It is lowlevel modulated as is almost all sideband radios but having run mine on 29.01 mhz AM it sounds just fine. I never looked to see how far down the power will go but WHY would you turn the power down????

Racer is 50% right you are a am guy you want a high level modulated rig. Spending upwards of 700 ( other 50% ) or more for AM is at best pricy. Most radios with ssb are low level be they HAM or EXPORT.
Now I OWN A FT-840 FULLY DECKED OUT and it will cost over 800 bucks to do that this again is a HAM radio and far more money that even a good 100 watt export set.
If you buy a ft-840 to use TRANSMIT ( not just lissin to the bands ...it's a GREAT shortwave reciever but am filter is REQUIRED HERE TOO ) For AM you MUST have the AM filter ( $130) so now you up at 700 bucks. For FM the board is about 60 more. On mine i have the 500 cps CW filter too ( $130 ) more and run A Radio shack Audio DSP. A lot of money for a radio but it covers 160-10 transmit and receives from about 100khz to 30 mhz in 10 hz steps.
AM is so wide band that the channel selector is most likely good enough. The digital tunning is meanless on a AM signal it splits it into more that 30 parts the 840 will tune 100 hz steps on AM and 10 hz on ssb/cw . You can be off 2 KHZ and still copy AM on most radios...... NO PROBLEM....that's 20 clicks on the 840's tunning dial. |

And it's true that most HF rigs are designed with SSB in mind. So the AM performance on an HF rig will not be as good as it would be on virtually any of the exports.

Bob_p - I disagree. I think an amateur rig is excellent. The receivers are better, once you adjust it properly AM sounds great, and the SSB performance can't be beaten. With the cost of used solid state HF rigs being so reasonable, I don't think you could get more bang for the buck.

Honestly, yes with the filtering and all for $500.00 for a nice used HF rig, you get quite a bit. But if you want to be loud on AM, I still think the S-3, or something it like, it would be better suited for his purposes.
Then if he wants the power turned down, that’s probably to run a linear. So in that case it could be a problem too.
And of course he's asking about 100% modulation, and as you said to get the most audio out of an HF rig, your going to have to play with settings, it's not like a CB, or export radio where they come built to scream right out of the box.

THANK YOU BOB !
Harley110 get a S-3 or one of the other AM only exports and youll be much happer than spending that much money on a radio.

Hey...maybe I need that HF radio to practice receiving code.
Or maybe I need it just for receive purposes.
I do shoot skip on the regular 40. It's not my fault...I can't help the way the atmosphere behaves.

Just because it transmits on AMATEUR frequencies & CB channels does not automatically mean that all are going to use it illegally...they might just appreciate the advanced noise filtering and excellent channel rejection ( bleed over ) that amateur type rigs DO offer that ordinary cb radios do not ( even the fanciest models ).
Do not automatically guess ( I did not use the word assume ) that every person who has an AMATEUR rig and only talks on cb channels uses it on freeband or amateur frequencies when they get the opportunity...most just want / need a better-than-average radio, which is what the AMATEUR rigs offer ( even the bottom-of-the-line models ).
Treat others like you want to be treated...be nice. |

Ok here it is,
If you wish to discuss the Legal aspects of radios or use of radios and what is Legal or Illegal to use and where PLEASE post them in the:
CB and Ham Legal Discussion Area ONLY!
It is no fun for the Moderators to have to waste our time answering e-mails from members and editing or deleting post's to avoid comments or flame wars directed at other members, that have NOTHING to do with the Original question.
Thank You!

Virtually all Ham Radios in the class of the ft-840 have variable power. They all typically vary from fully power to 1watt low.. Full power on these 100w radios will usually produce about 40w DK on AM and PEP aroung 80w. SSB is a real 100w PEP. I expect that there is an AMC adjust in all of these HAMs. If you never saw the inside of one UL be amazed..
If you go this route I highly recomend the ICOM735 as a base station. I have used two. One on a ship i was stationed on as the MARS OP and then i bought one off EBAY as soon as i transfered. wish i didn't sale it now. anyway too big for new car mobile use. I bet you can get one for about 300 on ebay
I used the icom 735 a little on am it had awsomely clear, clean tx audio but not LOUD. People knew you were on something different and i would say about 50% of my contact ask 1st WHAT Kind of radio are U on? It sounds NICE> :-) |
