Hi Jon, You might considerghpsdr3-alex using QtRadio. <http://napan.ca/ghpsdr3/index.php/Main_Page> 73, Rob KL7NA

Because the Softrock and associated PC are in an isolated room in the house, to keep everything in close proximity to the antenna, my radio servicing lab, etc etc, I have been trying to form a remote

The transformer wall warts are not regulated and will output circa 1.4X the rated voltage at no load, so “12V” has 16V output at the very low current draw of a Softrock Ensemble RX. A “9V”

Guys, I probably should have asked this years ago, but what power supply do you use for your Softrock?? I have both "wall wart" switching units and transformer type.? Right now, I've been using a

I wanted to make my Softrock ensemble cover all HF bands and increase the power output. I modified the Softrock so it could be used on all HF bands, and connected it to a uBitx that I was no longer

A +ve signal from a COM port. Controlled by the SDR software. 73 Alan G4ZFQ

What plugs into the PTT line on the Softrock 30/20 v6.2 board?

Some kind of choke or balun at the bnc that has dc ground will be protective to static and is a minimum. Lightning protection is difficult but you might look at various lightning protection like arc

Hi Alan, No, stereo mix/ mic, etc are not active.? I've turned off everything except what the card and SDR use.? Next step will be to switch out the SDRs since I have an identical one here.? See

Jon, This seems like you have a microphone active? Or, I wonder if you have "Stereo Mix" or, "Listen to this Device" set in Sound Properties or somewhere. This gives an echo effect. It will not

I tried to tackle the remaining interference today.? So far, no success.? It of course disappears if I unplug the connection from the sound card to the SDR. When I tune into those frequency spans

A few weeks ago, I finally put up a random wire for the Softrock. It has made a big difference in reception over both a simple passive indoor loop and an attic dipole.? It is made with thin magnet

Actually, I figured it out.? All this time, it appears I've had the HF and not the LF second unit.? A simple counting of the turns of the bandpass filters was the answer. Sorry to waste folks time

Jon, Then it is constructed as a normal HF Ensemble. Has it the extra chip? If so then there must be a link to make or break. 73 Alan G4ZFQ

That's not unusual ...? the name is from the What's important is that lsusb shows its correct VID/PID of 16c0:05dc ------------------------------------------------------------------- CUT

Much of that interference has been reduced, but not all.? Big step was making sure to place ferrite snap cores around all the cables.? I tried both a linear based power supply and switching with no

The important connection where the ground loop current is transformed into the interference voltage is from the SR audio output to the soundcard input. Try using a VERY short audio cable, with good

I have been using the LF, HF and VHF (built for 144 MHz) versions of the Ensemble II receiver. They all work well. But I have been using mostly SDR# (SDR Sharp) as the program. I'll check what

.? I also just set the LO multipliers to 16 (both of them), butI Jon, I can not see clearly but somehow you have an extra /4. The ABPF tab appears to have a figure in the Calculation column. It

Bob Although I didn't? get the transmit working properly on the Raspberry Pi I used the same setup? and procedure on a laptop with a Startech usb soundcard? and Linux? Mint and that appeared to?
