  • I admit that I did not consider the risk of RF damage to my machine, which I raw dog directly via the provided USB port on my 7300 to my MacBook. Risky, but those 16 thread FT8 decodes in JTDX are too tempting. My computer doesn’t even seem to notice it’s running 28 Firefox tabs, an NTP time sync, JTDX, and GridTracker.

    I would like to use some remote tools to interact with my rig, but the one solution I was able to find was $100. Dumb, I know, to fret over $100 having just spent a pretty penny to obtain a 15m mast… but still, the cost for the remote software has less perceived value than the mast.

    I’ve just been introduced (like, literally yesterday) to FreeDV, but haven’t made any QSOs yet.

    The digital space is wonderful, and I love it so much.

    I love these posts mate, keep them up.





  • Not quite packet radio, but there’s a huge community for FT8 (very very limited communications bandwidth), there’s also JS8Call, but it’s sort of slow right now (on 20m at least). You might be interested in SSTV; there are various bands of activity, some on 20m (14.230Mhz and 14.233Mhz) and certainly other bands as well. The advantage of SSTV is that the more popular platforms (MMSSTV, BlackCat SSTV, and fldigi) can take audio input from your sound card and convert it to the SSTV broadcast.

    Pair that up with any WebSDR and you can get nearly any broadcast within reach of your browser and the WebSDR in question.


  • For #2, a hard-coded 3 days doesn’t scale well. Use a divisor, like 10 or 100 and divide the purchase by it then wait that number of days.

    $300 headphones? Three day wait at a divisor of 100, or 30 day wait with a divisor of 10. You could even key it to your hourly income and then it also scales with how much you make. At $7.25/hr that $300 purchase should wait 41 days. At $25/hr it’s 12 days; this also allows one to make incremental savings to pay for it outright.








  • I haven’t tried any radials, and tbh I’m not certain to where I would attach them given the j-pole design has a matching network in-built. I’ve got a 1:1 balun at the feedpoint and an inline choke at the radio. My 10m antenna of identical design is great, and this one is great too (I see ~1:1 at 14.250), it’s just much higher in the band than I had planned and I strongly suspect it’s simply ground reflection since the radiating element is way lower than the halfwave it ought to be.



  • The window line j-pole is a monoband vertical, a half wave radiating element and a quarter wave impedance matching section. On 20m the overall length of this thing is 14.4m.

    On my current mast, the radiating element comes down to about 1m off the ground and then I have the matching section strung perpendicularly across the fence to keep it off the ground.
