Yup, with his then top of the line ICOM transceiver Art Bell managed a surprisingly clean, if slightly over legal limit, signal. (Calibrating S-Meters can lead to some surprising

You can have clean ESSB. Simon Brown, G4ELI https://www.sdr-radio.com

Or..they have found the essb setting..and want to be loud?

The IC-7300 is almost 101% idiot-proof. I was hoping the FTDX-10 would be the same. It *could* be the PSU but I doubt it. Simon Brown, G4ELI https://www.sdr-radio.com

It may be that it's a decent PA but the operators have an attitude, "I want to see 100 watts on the meter when I speak." Most hams on the air don't seem to realize that this is not a

I suppose they made it too simple for a lid to overdrive the transmitter. Or perhaps he is over driving his 10 kW transmitter. This is part of the reason I've been remarkably inactive

Ah, Shame – the FTDX-10 has a different PA module to the FTDX-101, I was hoping it would be clean ☹ . Simon Brown, G4ELI https://www.sdr-radio.com

I just wish operators of FTDX10's could learn how NOT to QRM the band! I have found ONLY ONE user of the FTDX10 that did NOT have a lousy signal... Exhibit A: The IC-7300's always have a nice 3kHz

Beyond the scope of my current interests.....I will let someone else do that if they like. Gedas, W8BYA EN70JTGallery at http://w8bya.com (under repair)Light travels faster than

I guess it is a good thing an ex-tempest engineer took the data :-) (have no fear, no unintentional RF leakage or coupling). Gedas, W8BYA EN70JTGallery at

Modulate the test signal. Try NFM with varying modulation frequencies and levels. The S-Meter's performance may lead you to some interesting conclusions. At one time I could make an NFM

Showing the raw data would be nice. There are a lot of analog RF effects that could upset the reporting, most notably cable leakage. {^_^}

It's not an easy subject to wrap your mind around. I'm sure I am not the be all and end all of knowledge here. But, this is a bullet I bit with my first USB toy, a USB 1.1 something

May I suggest to you that you take a slow cruise through the menu system. You might discover a whole lot of goodies you had no idea were there. (I am sure somebody else has already

Hi Dave and thank you for that snapshot of the transmission. It is really neat to see a look at the spectrum from the "other" side of pond of many of the signals that we

I have been doing some experimenting and based on my experience with other SDRs I still don’t understand what is going on. Comparative measurements are fine, but it appears that I cannot really use

For those who missed it, this is what it looked like during the warm up phase before the second transmission: a bit wobbly, but not bad for its age! Received near York on an HF+ and a Wellbrook
