Sadly I don't have my radio available. I always enjoy the Big Q. It's too bad they don't give out more information or at least easter eggs. This was my second pirate station I logged on MW, the other being Underground Radio.
I have a lot of respect for those who setup a horizontal dipole on MW since we're talking about a lot of space. I broadcast using a vertical on the same frequencies and never get noticed by DXers, and for obvious reasons being that the horizontal polarization allows for skip and vertical doesn't.
Speaking on and on and on... I highly recommend a longwire or T type antenna for logging MW stations. These guys use similar antennas to transmit. A full dipole is unpractical for most of us.
With AM it's not about just the long wire up in the air, it's also a great part about the ground. I know many ask how to log MW pirates. Put down a few ground rods. Try different grounding.
Okay I am dragging this post on, but if you want to listen to medium wave pirates, setup an antenna like a MW transmitting pirate. People forget that SW antennas have little top loading, and rarely a good ground. Fix those two things and you will hear things on MW that you never have before, and even LW.
Rant... long explanation... coffee haha...
By the way if anyone is curious I will go on about my thoughts on this... Just ask..
Actually Kage a vertical has a low angle radiation pattern. Look at your long-haul 160 and 80 DXers. They use verticals (loading the towers against ground and such). These are the guys that get the record setters more than not. Being a dipole cannot be raised high enough in most circumstances to prevent it from becoming a cloud burner (great for short-haul 500-800 miles). Of course I'm not talking about verticals with lengths no more than 1/8 or even 1/16 the proper wavelength in many cases. I consider verticals of this type no more than resistors raised in the air
But for receive it's obviously another story with verticals. Yes they generally receive from all directions but so do dipoles mounted only a fraction above ground against their wavelength. Yes they tend to receive more man-made noise sources. But for someone in a low noise environment this may not be an issue.
I live on a small lot and generally use my Pixel active loop more than the dipole. I can manage about a 140' dipole length at best though currently I'm using a 100'. I'm just north of Detroit so the noise levels can be high at times and this is where the loop really saves the day in many cases. I'm now looking at installing an active whip and phasing it against my loop for a "steerable" null. Several have done this with good success so that may be in my future for even more improvement.
