    I really enjoyed your 3 part video, I built a mag lop using a junk box condenser and made my loop more of a 8 sided pentagon with 3/4 copper . One interesting fact the 40m peak , was at the same location of my condenser as yours peaked and my loop works good on 40 and 20 m too . I copied Minn talking to Penn at S9 from Oregon (ssb). I really like your condenser and I want to build another one for 80M as the current loop is nil on 80M . The loop works on ssb but seems very good on cw signals in SWL mode. I really enjoyed your inventiveness and think process. . I am building a verticle too. But right now my random wire tree to tree at 30 feet above ground is better . Not sure of the SWR but use a MFJ ant tuner that really peaks the wire .

      +Gail Wisher Thanks :) Since these videos have been posted, I've found that the loops's operation really depends on luck. I replaced the inner loop with slightly thicker copper, and used less coax. That just won't tune up anywhere. On replacement with original inner loop, it worked fine. I probably need a bigger/ less touchy vari-cap. I'll probably build that when I have time. I can't actually afford to get variable vacuum caps, but those would be really nice to have (or a fun project...). On wire antennas, I've been having issues with SWR being low, but power out to antenna is also dropped (Not ALC action); one of the things on my to-do list is a roller inductor.

    No doubt you have a great future in electronics. Thanks for the videos.... de KA3LNA (Delaware)

    Kudos on the home made capacitor, cool! I used a geared down DC motor on my loop with a switch and resistor network to let me run it even slower for fine tuning. Another thing I did was a remote field strength pickup next to the loop. Makes tuning a lot easier since you just peak the strength rather than having to fiddle with a SWR meter.
    I go over it in a vid, here: 73

    You should ask if the freq in use be for u tx signal easy way to piss alot people off

    Is that an old Kenwood TS-130s? I have one of those.
