  • Ice Is Nice! first ride of 2026

    After reinstalling the dashboard rehab patient, I took Dorable for her first ride of the year

    Started out just under freezing, wound up just over,had a superb 35 mile ride to Lake Wissota State Park, a ride around the lake and the cruised Irvine Park in downtown Chippewa Falls.

    the state park staff have a pretty nifty rig to check the trails in the winter (I have seen it on wheels in the summer)

    The heated gloves I got last fall came in very useful yet again, thanks Savior Heat for quality gloves at a quality price.

    today also was the first outing for the new HJC I80 Velly helmet

    As well as the Osmo Action 3 camera I got used from B&H photo, I picked up a chin mount made for the I80 from chinmounts.com

    Hacked up the video from the cam and saw I only had it set for 1080/30fps, next run gets 2.7k/30fps

  • Repeater Gives Me Raspberries! Part Deux

    did some audio samples of the offending fruit,, only getting raspberries when there is modulation. Will try swinging audio levels to the other end of the scale. And If I can a different sound card.

  • Repeater Gives Me Raspberries!

    Setting up a replacement VHF machine for one of the club’s sites, its nearly ready to deploy. But there is a issue I cant work out. The thing gives everyone a randomly timed raspberry!

    its a MTR2000 with a Masters Communications RA-DR1X interface using a RPi4 running ASL3 asl3-3.7.1 using the SimpleUSB channel driver

    Have a listen, first bit is 1000Hz test tone with berries, then without the test tone and still with berries, the whizzing sound is the fan from one of the service monitors

    I have heard this on 2 other machines (Quantar and MASTR II) running older ASL versions and the USBRadio channel driver, at much lower levels and with less volume and fewer occurrences.

    I had always attributed this to the DSP driver, but in this case it cant be that.

    I do not believe I have any audio setting far out of whack, If I put 3Khz in I get 3Khz out

    Here are the parameters

    Device String is 1-1.2:1.0
    Card is 1
    Rx Level currently set to 500
    Tx A Level currently set to 500
    Tx B Level currently set to 500

    this artifact only occurs on receiver audio and is sent out both local and out to the network, not on audio from other sources

    This one has got me stumped, and everyone on air notices it right off.
