This morning (Saturday July 20), I went to the New Jersey Antique Radio Club (NJARC) Summer Swap Meet.

They typically hold three Swap Meets each year at various locations This time it was at the InfoAge Science

History Learning Center in Wall, NJ. The InfoAge Center has many exhibits including:

InfoAge Space Exploration Center

World War II Radar

Marconi Wireless Room

Radio and Television Museum

Vintage Computers

plus much more

Check out this link.

If you are ever in the area, I highly recommend a visit to it.

The Swap Meet was held outdoors and it was a hot humid morning – 80 degrees at 6 am with 90 percent humidity. By 9 am it was 90 degrees. But it was worth the hour trip.

I acquired one new radio – the Nova-Tech Pilot II Direction Finding 4 Band transistor radio. It’s in great condition and is working. It’s an interesting radio.

The four bands are Beacon (190-400 kHz), Broadcast (550-1600 kHz), Marine (1.6-4.5 MHz) and VHF (108-136 MHz).

There is a rotatable antenna on the top that is used to get your bearing. The top of the radio has the Bearing in degrees. It includes Squelch and DF Level controls; both can be switched off. The DF Level is the RF Gain and I read somewhere that when it is activated the AGC is switched off.

I was very fortunate in that the radio came with the three telescoping antennas – all in perfect condition. It also included the original AC Power Adapter.

All for only $25. A great bargain.

The radio seems very sensitive on the Broadcast Band.

I tuned it to my standard test weak station – WALK, 1370, in Patchogue, NY. This station is a 500 watt repeater station to WHLI, 1100 in Hamstead, NY. With most of my radios, I can barely hear a station in the noise. The exception is the Panasonic RF-2200 which can pick it up the best. The Pilot II could pick up a readable signal of WALK.

Very impressive.

Below are some photos of the radio.

Thanks for sharing this, Bill! No doubt, you snagged a fantastic deal on the Nova Tech Pilot II. My dear friend Michael Pool (who passed away earlier this year) acquired one and loved it. Here’s a link to his guest post about this cool DF receiver.

Thanks for sharing the photos and links to the NJARC swap meet. Looks like an event I’d certainly love to attend!

A 1960s Signal Sniffer

by The Professor

I just recently purchased a radio that on eBay that looks very intriguing, especially if you happen to DX AM Radio. It’s a mid-60s portable made in Japan – a Nova Tech Pilot II . However, wasn’t just a grab ën go to the beach kind of transistor set. This radio has a serious side. It’s actually an RDF – a “radio direction finder.”

I have seen these kinds of radios before, somewhere. Only the ones I’ve noticed were older and had more of a military look. Although I’ve never actually attended a hamfest, I’m sure these types of receivers might be found at a gathering like that.

But this is a smaller and frankly more stylish version of RDF. Not to go into too much detail about something I know little about, but before GPS became ubiquitous, devices like this would commonly assist in the navigation of ships and aircraft by pinpointing “beacon” transmitters at specific known locations.

As you might imagine, this type of technology was (and probably still is) a strategic tool for military purposes. In fact, one of more “infamous” incidents of using radio direction finders was when they were utilized by the Japanese in the bombing of Pearl Harbor. Their bombers just honed in on the signal of a Honolulu AM station (KGU at 760kHz) as their beacon.

So, this radio has three bands which were traditionally used by beacon transmitters. Besides the medium wave band, it also has a section of the longwave spectrum, and the VHF airband. Other models included the old marine band (around 3 to 5MHz). A later model also included the CB frequencies, and another included a VHF police band (called the Nova Tech Action!!).

So, no shortwave on this one. No FM either, but I have plenty of radios with those bands (like almost all of them). Of course, there’s not much to find on this side of the world on longwave these days, and listening to aircraft communications has its fans but it’s not something I’ve done much. But this thing has a unique toolset for medium wave DXing. And after doing a little research online I’ve discovered that the big rotating double ferrite on top is only one of the attributes it offers for AM DXing purposes.

For one, it has an RF amplifier in the front end to help pull those weak signals up out of the noise floor. For another, it has a pure RF gain function called “DF” (direction finder), which when turned on shuts down the AGC (automatic gain control) and allows you to tweak the RF gain any way you like. And it also has a very accurate tuning meter. That all sounds good to me.

So, I haven’t actually seen my Nova Tech in the flesh yet, and it will be probably a couple of weeks before I get a chance to give it a test drive. But I’m pretty confident in my purchase at this point. More than a few people have spoken glowingly of the AM DXing capabilities of this set. But one of the reasons I decided to go ahead and bid on this device was that not only did the dealer have an excellent eBay rating, but he says he also fully serviced the radio electronically and physically restored most of its original beauty. Apparently, it was cleaned up, recapped, and even a transistor was replaced. And he also aligned the AM band IF and re-peaked the antenna trim for AM and the airband.

Although this radio is still a twinkle in my eye at this point, I thought I’d mention it here in hopes some of the fine readers of this blog might have something to say about DXing with direction finding radios. And I was especially hoping that a few people might have personal experience with these 60s era Nova Tech receivers. I also noticed online that there are U.K. versions of these RDFs that were branded as “Bendix” radios.

All insights offered as comments are appreciated, and once I spend some time with this radio I’ll be sure to offer some of my own.

I always find it so much fun to await the arrival of an interesting old radio I’ve purchased on eBay, especially one that I’d never heard of before.

Thanks for sharing your find, Professor! I was not at all familiar with the Nova Tech Pilot II. I love the Transoceanicesque design! No doubt, it’ll be a handsome addition to your collection, and I’m willing to bet a MW DX machine as well!
