2014 I can hear non classical instrumental music, but it's tough copy with a weak/fair signal and a lot of local static from departing storms.
2102 Devo "Freedom of Choice"

Very Interesting!

Looks like I received them on 1700 kHz back on 2018: https://www.hfunderground.com/board/index.php/topic,46754.0.html

Back in 2010, 1710 kHz was Radio Celestial, with the rumor they bought the old Lubavitcher transmitter: https://www.hfunderground.com/board/index.php/topic,3890.0.html

Active antennas often send DC down the coax to power a remote amplifier circuit. They also typically have a DC blocking capacitor on the bias tee injection circuit to block DC being sent to the receiver. Yours seems to be missing that. You have to wonder what else it is missing.

Many (most?) radios have a capacitor on the RF input, which also would act to block the DC. If yours has that, it should be OK. If it doesn't, then yes, the radio could be damaged.

You could always add your own capacitor inline to the radio connection, to block DC. The value depends on the frequency range, from memory something like 0.1 uF should be OK?

SDR recording catch - quite weak, just a carrier.

A good signal here from sign on, for about 20 minutes before I had to disconnect antennas due to storms.

2141 Weak copy here, carrier, maybe some audio?

Hi NQC,

Yes, I've heard the argument before about operating in the MW band so the general public can tune in. I simply don't buy it. Radio listenership by the general public is at all time lows. Many simply don't listen to the radio anymore. Those that do listen to FM mostly (hence all the closures of AM stations). The few that do listen to AM are not tuning around the band, to see what's on those weird frequencies above 1600 kHz, where there's never a station to listen to. It's just not happening.

Even within the radio hobby, there's very few checking for MW pirates. This is probably (mostly) a case of "no one is listening for MW pirates because there's rarely any on... there's rarely any MW pirates on because no one is listening to them... no one is listening for MW pirates because there's rarely any on..." 

If pirates want to operate on MW, and and be heard, they need to be above 1710 kHz, period. Every so often I hear someone on 1620 kHz, and invariably they're getting buried under Cuba, or someone else. Occasionally they'll be heard mixing with Cuba, and rarely with Cuba in the background.   And of course 1710 kHz is jammed (I'm purposely using that word) by the Hudson County TIS Of Doom, with their now 5 year old recordings of where to go to get shots, with maybe an update about a road closure.

Not to mention the fact that the Pirate Act's multi million dollar fines don't apply outside the MW band.

I record 1600-1770 kHz 24/7, and use Carrier Sleuth to help me quickly go through the file and identify any possible pirate transmissions so I can then listen to them, either domestic or foreign DX (which I occasionally hear in winter). I even originally wrote it just for finding MW pirates!  Shameless plug for those who want to download Carrier Sleuth and give it a try, also handy with finding "regular" MW stations: https://www.blackcatsystems.com/software/medium_wave_carrier_display_app.html

But absolutely, advanced notification of transmissions is going to significantly increase potential listenership.

As far as why there's so little MW pirate activity (radio hobbyist oriented, vs those who think they're reaching the general public), I agree that part of it is technical. Antennas are larger and more complicated. Most modern transmitters can go down that far, and even older ones probably don't need a lot of modification since it's not that far from 160 meters - and if you operate above 1710 kHz, you're that much closer to 160 meters - another advantage!  ;D

Likewise for listeners, you need larger antennas to have a chance to hear low power (relative to MW broadcast stations) pirates. Being able to tune in the frequencies isn't an issue for hobbyists of course.  There's still other issues, static levels especially in summer. Propagation - you need night time paths for any chance of DX. And the best time for reception of MW DX is local mornings, not evenings.

IMHO MW pirate radio activity is a small niche segment of an already small niche - radio hobbyists.  I do think if there was more regular activity, that would lead to more listeners, leading to more activity. It's just getting to that point.

I think that's what happened to a large extent with 43 meter SW pirate radio activity, over the past decade or three it's gone from "I hope I hear a few pirates this week" to "Wow, there's ten pirate transmissions every day and there's three or four (or more!) stations on at the same time, I almost have too much to listen to!". If someone asked me "when was the golden age of shortwave pirate radio" I'd tell them "right now".

I should amend my last thought to 43 meter SW pirate radio activity in the *eastern* USA. It's still relatively sparse/rare out west. And I think it's the same reason - less activity means fewer listeners means less activity...

p.s. Maybe we should move this thread to the general discussions so others can chime in? Not many will see it here since there's so few MW pirate stations/listeners  :P

Excellent copy here on the SDR recording.

Thanks NQC !

Yes, It's great to see/hear the activity on 1720 and 1730, even in the summer! 

Once we get back to fall/winter, reception should be even better. Hopefully there will be some stuff to hear  ;D

Late SDR recording catch
0143 Already on the air / heard when the power came back on. Hearing music, not quite strong enough to ID.
0804 A bit stronger now, R&B music?
0920 Sign off

Late SDR recording catch

1131 Signed on, very weak
1134 Glenn Miller "A String Of Pearls", stronger signal now
1135 Radio Free Euphonia ID
... lots of QSB during the rest of the transmission, with the signal varying between very good and barely audible
1247 Off

SDR recording catch

2227 Signed on, quite strong, SIO 444, but unshazzamable music. Instrumental, modern jazz? Seemed like the same half dozen notes over and over, so it could have been  ;D
2246 Off

SDR recording catch

0043 Signed on
0044 Weak music heard - Def Leppard "Photograph" ?
0048 Eddie Money "Two Tickets to Paradise" - a bit stronger now

0056 Pink Floyd "Comfortably Numb"
0102 Rush "Closer To The Heart"
0106 Aldo Nova "Fantasy"
0111 Joe Walsh "Life's Been Good"
0118 OM speaking? "Uh oh"?

A very good signal here on the SDR recording.

Late SDR recording catch

0110 Signed on with Rage Against The Machine -  "Killing In The Name", SIO 433, some static from storms
