This is mine AWP-8. Restored it in 2018.

Bought in 2014.

This is mine AWP-8. Restored it in 2018.

I'm absolutely envious.
But I hope to catch up with you on this.

I just brought home the start of a new series, or rather, the continuation.
The first in a series of solid-state transoceanics is the Zenit Transoceanic Royal 1000 D.
It's in fantastic condition, just like it came from the store. So far, the only issue I see is the scale thread being pulled. The great thing is that even though it was found on eBay, it was a 35-minute drive from my house. So shipping was gas only, about 10 times cheaper than it would have been by mail.
Now, considering that the my last Transoceanic H500 is 70% complete, (the chassis is complete, and the body needs to be finished) all that's need to found is the very first one—the 7G605. But its price isn't inspiring yet. And the last two (maybe three)—the 3000 and the R7000 (D7000).

Vlad,

Is the R7000 the same as the D7000? I recently purchased an R7000-2 and am just gathering schematics and documentation. I can’t determine if D7000 is the same unit? Your new 1000D looks in excellent condition, congrats.

No, it's not the some. Different is not big, but any way it's other models.

Trans-Oceanic D-7000

Trans-Oceanic R-7000

[SRv2]

By chance have you come across a source for the front label on the R7000? My unit is missing that brand label.    

[Vlad95]

Should it look like this?
Unfortunately, you may have trouble finding this particular tab.
You can try finding a company that prints label like that.

Thanks for this thread, presently working on an H500. Restored some of these "T/O"s and have more on the shelf to be restored. Also have a Royal 3000 very nice radio, all that was done to it was cleaning.

Hello Guys,
Yes, I need to get working on my Zenith 3000 but this time of the year I am so busy.
hopefully this winter !

Sincerely Richard

Hi Vlad,

Nice job on the presentation! I have 4 Zenith portables:
-A 1948 Zenith 4G800 "Zenette"
-A 1947 6G001 "Universal"
-An 8G005 Transoceanic, earlier model with the 117Z6 rectifier
-A Royal 3000 Transoceanic.

The first 3 are functional. I recapped the Zenette. I need to recap the other two, but they are fully functional with no hum. A credit to the quality of the parts that Zenith used, 80 year old electrolytics that still function. Yes, they will be changed.

The 3000 needs to be recapped at the very least because, like most 60 year old transistor radios, this one is not functional. The chrome case has quite a bit of pitting (Chrome over pot metal, like 60s cars?) but I paid $19.00 plus shipping for it.

I picked the 8G005 over the others because:
-They sold for less than any of the other TOs, especially the unobtainable sailboat or bomber TO sets.
-No 1L6
-The loctal tubes are quite available and are"cooler looking" IMHO
-The push-pull output stage
-This one had a battery pack and extra 1.5V cell. There was actual residual voltage to the battery pack. Unusable, but there. I hollowed it out.

The chassis finish on both the 6G001 and 8G005 are in amazing condition, as are the bases of the loctal tubes. The wiring is still in good condition also. The cloth covering is not fantastic, but I did the shoe polish trick to sufficient satisfaction. I am more interested in the electronics than the aesthetics.

Yesterday, I finally cleaned it with rubbing alcohol to remove all traces of dust. I mainly do this to disinfect all the equipment I buy. It looks like it just came from the store.
I inserted the batteries and turned it on. Simply wonderful! It works just like it did in the store.
But ultimately, I was also disappointed. Not because of the receiver, which is flawless, but because of the overall condition of the old radio. This receiver, undoubtedly technically one of the best even now, is no better than my oldest TRF radios. Because there are only a few AM stations left on the BC band, and not a single, horror of horrors, NOT a single broadcast channel was detected on any SW band.
Although 5-10 years ago, there were over a dozen stations on the BC band, and some broadcast stations were present on all SW bands.

Overall, it seems AM broadcasting is on its last legs.

The 1L6 tube is rare and expensive these days. This tube is used only to support the high-frequency SW bands above 10 MHz. Below this range, a regular 1R5 tube works perfectly.
This is incredible because these tubes are truly very different, but it works if you use a 1R5 instead of a 1L6, simply by installing it in the base!
And this even works for the 25-19-16 meter bands. It might be slightly less stable and sensitive, but that's not important right now.
I've already mentioned this trick and tested it on all my radios equipped with a 1L6 tube. I might try the opposite trick – a 1L6 instead of a 1R5, just for fun.
As I wrote above, we no longer need to worry about supporting any channels other than BC, since there are currently no such stations.

[Vlad95]

No, it's not the some. Different is not big, but any way it's other models

I was wrong.
This is true for the Zenith Transoceanic D-7000 and Royal-7000.
Both models have a similar circuit using transistors.
But the latest model, the R-7000, is completely different. Its circuit is implemented using integrated circuits.
And it looks quite complex.

Hi Vlad,

I heard that and yes, the 2 tubes are radically different.  I can't quite remember but I think that someone had the same situation with a 6A8 vs a 6K8, again 2 very different tubes and the 6A8 somehow worked, at least for Broadcast Band.  I whipped out the ol' RCA Receiving Tube Manual and scratched my head.  I can see similar tubes work where one is optimized for shortwave, such as the difference between 1LA6 from the Zenith "Universal" (6G001) vs 1LC6 from the Zenith "Transoceanic" (8G005), but the other tube?  Somehow, when I looked at the others, I could see in a twisted way how they worked.

True, regarding Shortwave, everything is drying up except for a few religious and special interest stations.  However, we have many AM stations here in the New York Metro Area, almost all being news / talk or sports, religious or foreign language.  Shortwave service to the US from developed countries and institutions, such as Britain, France, Germany, the Vatican, etc. have shifted to the internet, and their shortwave signals are beamed to the developing world.  I think that maybe even the 80, 40 and 20 meter ham bands are drying up because the previous generation is drying up.  Heck, my generation is drying up!

I think that there are several factors at work here:

• First off, the FM broadcast band offers superior fidelity and freedom from noise.
  
• Secondly, the noise from all the EMI out there (CFL and LED lighting, WiFi, Smart homes, remotely read power meters, switching power supplies, and electric vehicles.  There is a lot of talk about Auto manufacturers, especially Tesla and possibly Ford, dropping AM from factory installed radios.  (I remember that in the 50s and 60s, some Euro cars came equipped with at least one shortwave band on their radios, in addition to AM broadcast.  I think that even Long Wave was popular in Europe.  You would know better if you grew up there.)
  
• Thirdly, I think that subscription radio (Sirius XM, Etc.) MusicChoice on cable, etc. is cutting into the need for AM.
  
• Fourthly, the amount of time spent on podcasts, social media, computer and iPhone screens, etc.  A bad source for news.
  
• Finally, I think that so many consume their music from their iPhones.
  

As a kid and later as an adult field engineer, on late fall nights, I used to like to "AM DX" either with my AA5 Emerson or the car radio (especially the ones in the late 80s, early 90s Dodge Caravans) and was amazed to pick up CKLW in Windsor, WLS from Chicago as well as stations from Atlanta, Boston, Buffalo, etc. I even picked up a non-clear channel station from Tennessee. But that's how "skip" works.

I would think that there are about 5 clear-channel high power and about 7-10 other relatively strong AM stations that I can receive in the car if on the local highways where there are no power lines, trucks with GPS and telemetry, etc.  In the house, it is VERY different.

I bought this Zenith Transoceanic D7000Y 5 minutes ago.
Now my Zenith Transoceanic collection is almost complete.

[Jimradio]

Just purchased an RCA 6BX671 a couple of weeks ago, looking forward to your restoration article.
