Sounds like ground side is coming in fine again, so it must have just been a bit of bad reception. I got a question for you HF guys... What kind of setup do you run to pick up the HF? Are there special scanners or antennas involved? For example, would I be able to pick them up with my current setup?

John, you need a shortwave receiver with sideband capability, as well as an appropriate antenna. Before even attempting I would first drive around your neighborhood with your car radio tuned to a weak AM station high on the dial (1300-1600) and see what kind of powerline, computer and TV noise might be in the area. If you are relatively rural (low noise level), you might be able to get away with an amplified vertical antenna like Dave uses up in NH, but the cheapest thing, property and available trees permitting, is to string up a simple horizontal dipole wire antenna, which can be more directional and picks up less man-made noise. For two of my three HF feeds I use old Radio Shack DX-400 portable receivers acquired at an average price of around $40, which can be modified to give pretty good performance, however with those consumer rigs you MUST have a narrow filter when using an external antenna because they will bleed all over the place at night when the HAMS and foreign broadcast start to pound the airwaves. Fortunately such filters are very cheap to make, needing nothing more than a couple inches of 2" PVC pipe, a few feet of rg-58 coax and a soldering iron. The Radio Shack solution is the best performance for the money solution I have found yet for HF. They are cheap, though they are old (from the 80's) and have common problems you need to look out for when buying, they are pretty stable if kept in a fairly temperature controlled environment, can give decent reception despite the use of a BFO instead of a product detector for sideband demodulation and are digital entry, which makes frequency selection easy.

There are also some USB dongle SDR (Software Defined Radio) receivers that work with a computer, which allows scheduled frequency hopping (higher bands are used during the day, lower at night) but they also suffer from poor selectivity and would require a filter or series of switched band filters. A step above that (as far as computer control) are pricier SDR's , often used by HAMs, which have much more selective RF circuitry and are essentially like the complete RF section of a radio without the audio back end or front panel controls, as well as many general coverage receivers, mostly made in Japan under well known names such as Drake, that are complete stand-alone receivers that may also have computer interface capability.

Finally there is used commercial gear, some legendary with names like Harris, Racal, Rockwell Collins, etc. from modern solid state ("sand state") back to "hollow state" tube rigs from the fifties and sixties that give extremely superior performance. I personally like the old, heavy stuff, but you need to be able to maintain it. My 6577/5550 feed uses a pair of somewhat legendary R-390 radios working together with a rarely seen CV-157 sideband converter, all configured (using only a hundred tubes) to merge and demodulate two different frequencies at once. It's different from simply merging two audio streams, the stronger signal from either receiver will suppress the signal or noise from the other. The feed is primarily on those two frequencies, but depending upon the band conditions ARINC may also go up to 8846 or 11396 during the day and down to 3455 or even 2887 at night, so if I am around and monitoring the bands in use I will re-tune the radio pair to track the primary and secondary frequencies in use at the time. Due to the heat generated in the equipment rack they serve double-duty heating the shack from fall to spring, but I do not run those rigs 24/7 for the feed in the summer when I would have to air-condition them and am often away and unable to babysit them anyway, so I switch to a pair of DX-400 rigs modified to work together in diversity reception the same way the boat-anchor rigs do.

Thanks for all that info. I had a feeling special equipment was needed. I'm not really planning on trying to get anything HF, I was just curious. Maybe someday I'll give it a try. Sounds like there's a lot more involved than picking up the VHF frequencies.

I don't know that it's harder, just different. In fact except for localized sources of interference that are generally not a problem with VHF, HF is in some ways easier since, with the same equipment you in NJ, me in CT and Dave in NH would be able to receive the same signals at about the same strength most of the time, whereas with VHF you can pick up the ground side of 133.5 where he and I never will, and there are other complex forms of interference or challenges to reception that often require specialized test equipment and significant expertise or experience with two-way radio. Anyway, there are some coverage gaps in HF for the Caribbean and North Atlantic routes, for example 3016, 5520 and 8906, so first you (or others) get your hands on a portable SW receiver or spend more time listening to the HF feeds and see if you catch the bug. Except for my two decades as an active pilot, I almost never listened to VHF unless in the cockpit, but have listened to aeronautical HF since I was about ten years old.

Maybe someday I'll give it a try. I'd try now, but you know how money always keeps you from doing anything fun. First thing I gotta do is split up ZNY and WRI/NEL.

I hope we will decide to add 133.5 back onto the ZNY part of the WRI scan before the storm moves in Tuesday! Should be some very interesting listening Tues & Wed...even if its all busy!

I do have an idea of how to include 33.5 in preparation for the storm, but it would only be a temporary solution. I could see how it comes in on the dedicated CTAF scanner, and if I get the ground side, leave it on there from Tues-Wed (in addition to the CTAF's). The local airports aren't too busy this time of year, so I wouldn't be missing much. The only problem may be that I think the CTAF scanner has a lower sensitivity, so I might not be able to pick up ground. Well, Dave said he'd be back tomorrow, so I'll see if he has any suggestions. The final decision of course is up to him.

I only say that cuz you had it in your scanner before when you were scanning 118.97, 125.32 & 133.5 together a day or so ago... All received ground-side fine. Whatever you (and Dave) can do is appreciated...

That's not a bad idea. CTAF's are probably less busy, especially if you can't pick up those little planes when they are on the ground. Just use the delay on 133.5 and not the others, to try to hold both sides (assuming you can pick up both sides with that scanner). It would be nice to monitor that freq from your location for a while, because as I said I am not sure you are picking up the arrivals when they first check in, which is at maximum range and may even be over your radio horizon. Even the Long Island south shore ARINC 129.9 feed can miss a plane here and there out at ZIBUT or OKONU, especially if they are at lower altitude, and that's an excellent, purpose designed antenna and amplified feed line system at almost sixty feet and in the clear. The check-ins are usually fifty miles even further south of of those waypoints, which theoretically you should be able to get if you had the equivalent performance because you are almost fifty miles closer to most of them. You may literally only get them at low tide... I'm not kidding. We'll see.

I'll put 33.5 on the CTAF scanner for a little bit right now and see what I get.
Now to find the manual so I can figure out how to program that scanner again...

Okay, holding 33.5 on the BLM feed for a little while. On a side note, the ground side of ZNY is coming in great tonight. Must be good atmospheric conditions.

I think it sounds like ground is coming in. I have no problem leaving 33.5 on during the storm, but I'll wait to see if Dave has any objections or other suggestions. I'll leave it in the scan with the delay until I hear back from Dave.
Okay, I don't see a delay button, so I guess there is no delay feature. Maybe it's on by default.

It's good to hear that you added 133.5 again. That's always a good frequency to listen to. The radio shack has a delay button, the bearcat does not. A delay is automatically included in the bearcat, you can't turn it off (unfortunately). Thanks John!

Yeah, I think I could live with this setup until I get myself a dedicated NEL/WRI scanner. As an aside, I see you have a Galaxy S4. I just ordered one Friday, and it should come tomorrow. Looking forward to replacing my iPhone.
Wow, I can't believe this is up to 73 posts. I really wasn't expecting my feed(s) to become so popular.
