[Elecraft] RF feedback? only when using KXPA100

This did not used to happen; it is new to my set-up, nothing I am aware of has changed... When trying to operate JT65, if I set the power to 10 watts, everything is fine (KXPA100 is not active). If I set to anything above 10 watts (yeah, like 11 watts or more), I get bad RF feedback (sounds

Thanks Brian. I've been reviewing my test setup. Because of limited USB ports on my normal station computer (laptop) I have been using a new (to me) desktop I'm building to be the station computer, to run both WSJT-X and my SDR-IQ software (SpectraVue) for this investigation. The sidebands

[Elecraft] KX3 Heatsink discussion

I'm puzzled by the comment posted yesterday: by Jim W7JR ""I've been doing a lot of FT-8 using my KX3 and my KXPA100 at 20 watts, and have noticed that the KX3 is heating up quite a bit and is almost hot to the touch"" Why should the KX3 be heating up, when the AMP is running only 20W ? Is the

Re: [Elecraft] K3: Odd ALC behavior

I was thinking that as the "ALC" meter isn't really showing ALC, but audio level when below I believe 5 bars? - that the ALC isn't being modulated, rather what we may be seeing is an artefact caused by the way the peak level of the audio is detected by sampling the audio at a particular

Re: [Elecraft] K3: Odd ALC behavior

I said earlier: "If I set the tone to 1500 Hz, the FT8 mid-band target, I'm presented with the cyclic ALC and some ~193 Hz, -50 dBc sidebands. " Ten KHz/div is too coarse to see these. Try again. Wes N7WS On 8/5/2017 1:01 PM, Brian Hunt wrote: Here are some spectrum photos from the tune

Re: [Elecraft] K3: Odd ALC behavior

Here are some spectrum photos from the tune signals of both FLDIGI and WSJT-X 1.8. All three are essentially identical showing some low level sideband noise +/- 30 kHz and down > 60dBc. There's no apparent difference in the spectra between pumping and non-pumping ALC, as Wes reported.

Re: [Elecraft] KX3/KX2 CAT to Rigblaster Advantage

Erik, Use the RS-232 interface, but you will need the KXSER cable to connect the KX3/2 to the DB9 connector. You can order it from Elecraft or construct your own. If you do not have the parts on hand but still want to build it, order the kit of parts W1SERKT from Elecraft. I am certain

Re: [Elecraft] K3: Odd ALC behavior

Except when the sound card is in the computer instead of the radio, "Line In" is receiving signal from the program via the sound card 'speaker' output, not the microphone. Moving the card into the radio doesn't change this. The only thing changed is it's too darned sensitive. Regards, Wes

[Elecraft] KX3/KX2 CAT to Rigblaster Advantage

The Rigblaster Advantage has both 3.5mm TTL CI-V/CAT and DB9 RS-232 interfaces, but it’s not clear which would be best to connect to the KX3/KX2. Googling found old posts that the KX3 ACC1 is flexible enough to handle either, so easiest would be a 3.5mm stereo mini cable, but does it have to be

Wayne, There are no beat notes. These frequencies, at least from the FT8 program in Tune mode are single frequency. Based upon output RF spectrum measurements*, with for example 1010 Hz input and 4-5 bars of ALC, I see spurious or intermodulation sidebands, down -65 dBc. If I change nothing

If you get a set of Beyerdynamics velour pads, you'll never go back to that flaky vinyl surface that OEM Yamaha and Sony use. They may even be to exact same size too , so I'd bet the Sony type will fit the CM-500. I have both and they look identical. They're a tad pricier at about $23 than the
