Hi John, Scrolling of the image would be fine. Maybe an Shift-right click on a suitable top alignment reference point (e.g. image border) and an Shift-left click (or similar) on the same point towards the bottom half of the image could be used to se…

Hi John, Some other suggestions. Would it be possible to use something like Shift - Click on FAX to align ? It's too easy to accidentally click on the image and mess up the alignment. A double action would fix that problem. Would it also be possible…

Hi John, Is it possible to have the option to default to the currently tuned frequency rather than the first pre-set ? This would allow non-standard or newly discovered frequencies to be more easily used. Plus can the audio be muted when the Fax de…

Hi Kari, OK - that fixed it :-) Thanks for the quick reply and even quicker fix ! Regards, Martin - G8JNJ

Hi Ron, I don't really have a favourite. It's just that I remember using a radio with Ham Radio Deluxe that had a DX spot 'click and tune' feature that was quite useful, hence the suggestion for further discussion. It would turn the KiWi into an act…

Hi James, OK understood. In that situation I think input protection diodes would probably be the least of your problems :-( Regards, Martin - G8JNJ
-
Hi James, The loop is relatively small so the level of field strength required for the diodes to generate IMD product above the noise floor would generally need to be quite high. Unless you are living very close to a Broadcast site it's unlikely tha…

Hi James, I replied directly but thought it may also be of interest to others. This is an interesting design, but I notice that the common mode attenuation figures are quoted as dB in a 50 Ohm system (which is fair enough in itself), however the com…

Hi All, I think you may be able to achieve this by using something like Auto-it (free). https://www.autoitscript.com/site/ I have used it in the past when running WSPR to change bands in different sequences depending upon the time of day or night. …

Link-11 frequently appears in pairs separated by approx 3.6KHz When tuned to using USB, the lower dial frequency of the pair tends to be XXXX.7 and the upper frequency tends to be XXXY.3 Regards, Martin - G8JNJ

Hi Ron, I made a mistake in my last posting. I said DARN but I meant HAARP. DARN is active and can be heard sounding like a road drill as it stays on a frequency for a few seconds before moving to a new one. Regards, Martin - G8JNJ
-
Hi Ron, As far as I'm aware DARN is only occasionally used these days when they can afford to put some money in the electricity meter. However there are a whole host of other atmospheric sounders and radars that can be heard almost continuously. Her…

Hi James, You misunderstand, my suggestion was to place the ferrite bead and resistor at the amplifier input (in series with the whip) as shown in the link that was later posted by John. http://www.pa3fwm.nl/technotes/tn05.html#lpf This method work…
-
Hi James, You should be able to fix the FM BC interference problem that you have with the Clifton whip. Three or four turns on a small single hole ferrite bead in series with the connection from the whip to the amplifier should do it. If not add an …

Hi John, This is excellent. Are you moving towards being able to setup background WSPR decoding when there are unused receivers available ? Ref to https://github.com/jks-prv/Beagle_SDR_GPS/issues/49 Regards, Martin - G8JNJ
-
Could the Squelch muting also be used to temporarily stop the audio stream in order to conserve network bandwidth ? Rather than a simple level based squelch could some form of 'intelligent' speech detection algorithm be incorporated ? Regards, Mart…

Hi John I think I'd prefer it to remain an admin only option but with an extra confirmation dialog. Regards, Martin - G8JNJ

Hi J-Luc, It may be that your SDR I/Q balance has been disturbed. I have had this happen to me when a user adjusted it incorrectly. Open up the IQ_Display extension. Set the IQ gain to about 80dB. Disconnect the antenna at the SDR so that no signals…

Great - thanks for adding this John. Regards, Martin

Hi All, Ron said "I've written to Andr?s and suggested a different rating system for the receivers listed at sdr.hu . You never know, he might consider a usage based rather than a vote based rating system." Ha ! and just as I've managed to…
-
I think Phil's suggestion of a last used frequency memory would be useful. I often find that I listen to one frequency whilst scrolling up or down the adjacent spectrum. If I quickly tune to a new frequency to hear what's been transmitted, it would …

Hi John, Your kiwisdr.jks.com:8074/admin running 1.83 works OK for me on the PC I previously had problems with when running 1.81. Regards, Martin

Hi, I also have this frustration. I've tried to assist where I can by sending personal emails to admins where I think I can help improve things. But unfortunately in some cases the Admins are more software orientated than having any real interest …

OK thanks John. Martin - G8JNJ

It doesn't work for me with local IP and Firefox or Chrome. Cookies cleared in both cases. Regards, Martin

Hi John, Ah OK, I haven't updated my main public KiWi. The KiWi with the problem is at http://southwest.ddns.net:8077/admin. How is this ? Uncaught SyntaxError: Unexpected token )kiwi_util.js:396 getVarFromString: NO SCOPE cfg.ant_switch.denymixing…
