847 hidden menu to make the receive more sensitive

[wheel bender]

I out worked my friend's yaesu with a delta force on fm mode. He wants to know if he can open up the receive a bit to hear the weaker stations, any help will be usefull.

Any service menu settings that increase RX gain will also increase the noise level.

Did you test them side by side on the same antenna?

Personally, I'd be wary of chaning service menu settings. an 847 would make for a pretty expensive paperweight!

That's the important bit, a chap local to me works hf pedesrian mobile and he can be 1/2 a mile away talking states side and can barely hear who he's talking to (ok so my antenna's crap )

Side by side, and using the same antenna.

I also suggest your friend buys himself a bhi nes dsp speaker, massive difference on receive, much better than the built in DSP on the FT847.

1) The 847's recieve on HF isn't that great - it's primarily a VHF/UHF multimode.

2) Anything you change in the menu to increase the gain will increase the noise also.

3) Anything you change in the menu to increase the S-meter reading will not necessarily increase the actual signal.

4) The 847 will make an expensive paperweight.

5) In case you missed the point of the other points above - leave it alone!

We wern't running on the same aerial. Thanks for all your replies. I'll pass them on to him. He tried altering the secret menu and as you say only increased the noise level. I know exactly what you mean about it not handling 27mhz like some other radios dedicated to those frequencies can. Thanks again for your replies. He's waiting for a Delta force to arrive.....Lol!

I'm willing to bet an 847 will outperform a Delta Force on 11m.

I'll have a pound on that too my moneys on the 847, and that's after owning both at some stage

But, Yeti, many people in here think that a higher S-meter reading means it receives better...

Oh FFS....

There probably is nothing wrong with his Yaesu and everything wrong with his antenna. You cannot claim to have "out performed" his Yaesu unless you were on the same antenna.

Congratulations on probably getting him to waste £200+ to see no improvement.

Mine too. Wheel Benders comparison was not a true one because his antenna is probably working far better.

I have two antennas here. The CP6 on 20m is 6dB down on the 20m dipole depending on location of the other station. On stations in Russia, the dipole will sometimes hear stations that are completely unheard on the CP6 and vice versa if there are stations to the south.

So unless he went round to his mates house, unplugged the 847 and plugged in the Delta Force, then its not a fair comparison.

I reckon there's £200+ just about to be thrown away.
