  • F****r! QRM (not rude btw)

    PowernumptyPowernumpty
    I posted this to the UKQRM group.
    Turns out this specific issue and charger type was mentioned in RadCom (RSGB magazine) a few months back.
    The actual issue is that the manufacturers are leaving off… (more)

  • OV display time adjustment needed

    Would not an OV per minute with logging or max hold be better than relying on the the visual indicator?

    Always good to hear it worked in the end!

    That Beagelbone voltage dip thing has caught a lot of people but the general power management and control has probably saved more hardware and installs than… (more)

    Why is it not good?

    I know feeding 5.3V to the Kiwi sounds a bit agricultural but I have unintentionally fed much more than that into the Kiwi (not Beaglebone direct) over an extended period without… (more)

    Thursday I noticed my WPSR results and spot ranking had tanked, I check a receiver and there was an almighty level of QRM, checked the noise charts and spotted that it started at around 8:15 the… (more)

    One for Rob (no follow up needed),
    Checking my Grafana plots, 40m together with 60m were virtually a straight line, all the others looked normal.

    Long story short I had a -1000dBm/1Hz recorded at the… (more)

  • Listen together with another user

    PowernumptyPowernumpty
    Hi Tom,
    Quite interesting idea to have a "follow" feature, would probably need the users permission (or a pop up "user x wants to follow") or it gets a bit creepy.
    Yeah, "stalker mode enabled...".

    Project needs a "Thermal Cape"
    I've ordered some bits as my scrap box only has a couple of heat pipes and both need a lot of work, would get round the space issue though.
    This is just waiting for some… (more)

  • KiwiSDR + MLA-30

    PowernumptyPowernumpty
    The ML-30 has an impedance mismatch that means there is a noise spike around 5MHz with the supplied loop, DSL creates loads around 15MHz so phone lines are an issue.
    That said for a balcony install… (more)

  • Noise at roughly 60 KHz intervals

    It would be interesting to test both the ethernet cable and the supply to the Nano router with a few turns through ferrite.

    This is a remarkable difference so I assume the Kiwi is also physicaly very… (more)
