Did you use the WAN IP address or URL? And in the latter case: with or without " etc?

I've connected successfully (for Rx only; did not try Tx) with a Remote Quisk rig in New Zealand (from East Coast USA) ... round trip was about 205 msec.

I hooked up a MIFI unit to emulate a real life internet connection, but it did not work out. All forwarding was set as laid out in the Remote documentation, but to no avail. I called the MIFI (server) using its URL as well as the actual WAN IP address, but no succes. The round trip delay is fairly high, 50 to 200 ms, hence I wonder if that could be the cause why connection was not established?

Hello Jim,
Keeps getting better, LNA slider works as you have said and is the best solution. I have one bug to report which has been through several recent versions: The Config/TX Audio screen has no boxes to display the audio levels anymore. They were pretty handy for setting mic gain although it can be done just as well by using FDX and observing while making sure no clipping is happening in Pulse Audio Volume Control for PA but a little more care is needed for alsa.
I don't know if it is a bug in the software or RF breakthrough but after a period of transmit the graphical display freezes on my remote. Everything else works fine and I can tune with the cursor moving but nothing else on the frozen graphical display. TX and RX are fully working and if I shut down the Ctl-Head and restart it all works fine again so the graphic channel had not stopped from the remote and VNC viewer also shows it running on remote when Ctl-Head is frozen. I'm reluctant to report this as a bug as it could be RF getting into my system but over the last 3 days I have put common mode chokes onto every ethernet cable at both ends and run the remote via wifi further eliminating RF into CAT-6 cables. Another thing that makes me think that it may not be RF is that it happens on all bands which I would not expect from RF breakthrough as it tends to be frequency independent. I would be interested to hear if any one else has experienced this issue.

Hello Nigel,

Thanks for the screen shot!

I'm not sure what the mountain in the middle is, but the I/Q calibration is used to remove "ghost" images mirrored around the VFO frequency.

In your screen shot, it looks like the VFO is at 9995 KHz, with WWV at 10000 KHz (5 KHz above the VFO) ... looking for a mirror image of WWV at 9990 KHz (5 KHz below the VFO), I don't really see anything, which is good.

OTOH, we may be seeing a mirror image of the 9980 KHz (15KHz below the VFO) broadcast station at 10010 KHz (15 KHz above the VFO).? Does changing the I/Q balance change the amplitude of this (possible) image?? If so, that shows that I/Q balance is making a difference.? If not, perhaps it is simply another signal.

NOTE:? We may be able to see the (possible) 9980 mirror image much better than the WWV mirror image, because the? 9980 broadcast signal is about 20 dB above WWV's signal, and its (possible) mirror image is just about 20 dB above the noise floor.? WWV's mirror image might be just at or below the (somewhat stronger) noise floor at 9990, masking the image.

Suggestion:? To avoid possible strange results from listening outside the intended range of the receiver, try finding one or more strong CW signals in the 40 meter band ... look for mirror images on the other side of the VFO ... it's easy to visually tell if it's a mirror of a CW signal, based on when the signal is keyed vs not ... you can even listen to the mirror image to listen for the same call sign, or CW tempo/style.? BTW, it's good to calibrate close to the frequency you are intending to use, as I/Q calibration can shift somewhat with frequency.

Good luck!

OK, I will have to drag the service monitor up there, but will have to wait until the snow clears a bit!? I thought I could adjust it by tuning a carrier, of which there seems to be many.? I can get a good signal from WWV on 10MHz in? the evening, so the frequency calibration is spot on.

Understand about the remote - I am using VNC to access the headless node.

Another thing is that Tony Parks sold me this as a 4-8 MHz RX ensemble, so I'm wondering how much of what I am seeing is images - certainly not WWV so I wonder if he shipped me a wider-band one by mistake.

Not sure if attachments go through here but I will try - the 10MHz WWV signal is perfectly readable and the over-modulated signal at 9980 is a religious broadcaster.

I assume that the mountain in the middle is what I am supposed to be getting rid of!

Hello Nigel,

I tested on a local machine (no remote feature) with my RxTx Ensemble and everything seems to be working. When I inject a sine wave, the slider controls adjust the image to zero. And I don't see a frozen graph display. Note that you can not adjust the image from the control head in a remote setup. Adjust at the remote. If you still have problems, please describe more completely. And send any tracebacks.

Here is the working version of the tune botton widget. Thanks to Harald, OE6HKE.
