Re: What I like collecting.
Nice collection, thanks for sharing, as for me I like the older destop receivers, also since they're easier to repair

Re: The SULA antenna
also, since you have two 9:1 ready, and since you seem to have some room, if you want, pick a lenght of insulated wire and lay this antenna down

and I mean LITERALLY down on the ground

Re: The SULA antenna
You're welcome
If you can and want, please come back with some feedback after you'll have tested the SULA for a bit, it will be welcome and useful !

Re: The SULA antenna
Nope, I wrote it, the 73 is ok for lower frequencies, as for aiming the loop, I'll repear, the SULA is a directional antenna, so yes, you'll want to aim it at the desired signal

Re: The SULA antenna
As for the noise direction, I think the noise comes from different sources, regarding aiming the antenna, the SULA is directional, so it needs to be aimed, and then I suggest adding a preamp at the antenna Regarding the transformer, the turns ratio is the square root of the transformation ratio, so ...

Re: The SULA antenna
the sula size, resistor and height have been optimized for the "diamond" shape, so changing shape or size will require remodeling and optimizing the antenna, that said, yes, try raising the resistor value and also lay the coax so that the section coming down from feedpoint is long about 1 ...

Re: The SULA antenna
Late to the party :D Ok, here we go, I quickly built a NEC model for a round loop which should be pretty similar to your octagonal, the results of the simulation are below, notice that to recover the cardioid I had to change the resistor value to (around) 642 Ohm, also notice that the horizontal pat...
