Locked Re: How to build a simple loop for the 15m band?
If it a receive only antenna you'll probably be alright ... If you need a little more capacitance you could parallel a fixed cap with a trimmer ... the main drawback is you'll probably only have 20Khz

Locked Degen 31A & 31MS Loop Antennas
Howdy Len and all, There sure must be something different between the 31A and 31MS control boxes, I have not opened them up to see what it could be unless of course my 31A control box is faulty!

Michael, thanks for a most interesting comparison. I won't quote the whole of it in my reply [ hint, hint ;-) ] This performance difference is intriguing. According to the DRM Software Radio Forums

Locked How to build a simple loop for the 15m band?
Dear community, I am searching for a simple solution for building a material-saving magnetic loop for the 15 m HAM band. If possible, I would like to use 0,8 cm flexible copper tube. Unfortunately, I

Howdy, I have found following indepth experiments today that the Degen DE31MS has a far superior tuning box compared to the standard 31, the MS version has better gain and slightly better signal to

Hi Len, I have uploaded a picture of the TG33 loop head unit for you. You can find it n the photos area under TG33 loop. As you will see, the TG33 MW loop uses an inductor in much the same way as the

Thanks for the reply. I decided to map my property today and found that I have 4 trees not quite at 40' and not real square but will do the job and it shortens my feedline run. Now all I need is

Hi Len, Please see my ost on the internals of the DE31MS loop head. The MW position utilses a bulk inductor to increase the the effective loop inductance. This may explain the odd ratio results with
