Becky;

Thank you for signing in from Zimbabwe! And glad to hear your experience with that cheap shortwave receiver kit. It seems like the coil in my kit was bad if yours worked. Hope I have time to investigate it more.
Because CIC 21-020 is basically a crystal receiver plus RF and AF amplifier, good selectivity was not expected from the beginning, and indeed, it was poor.
If more selectivity is desired, I think adding a regeneration circuit will be practical and interesting. Using FET and building a coil will be necessary. Some kit manufactures such as Vectronics and Ten-Tec offer regeneration receivers.

Take care and good luck!

Found your website while looking for information on the Hammarlund HQ-170. I need IF transformer T1 to restore this radio. Any idea where I could find one?
Thanks, Dave

Hi,
great to find your site. Just built the SW receiver CIC 21-020. Got it to work without replacing the tuning coil, but a 20ft antenna at dusk did the trick. Also found selectivity impractical.

Your site for this kit is in Japanese! Did you have any ideas of how to make this practical or know of any other cheap, but practical SW receiver designs for the 50m band. I'm a bit of a beginner out in the sticks (backwoods of Zimbabwe) and I need all the help I can get. Thanks...

Seems like tube testers are still have demands. Although
the TE-50 is a simple tester, one may pay 40 to 60 dollars
for it. If two buyers get hot in an auction, could be more.

I'm also looking SBE SB-36 schematic and information.
I know it was made in Japan, and supposedly the rig
was marketted in Japan as well - it was the first
digital readout rig in Japan. I'll let you know when
I get the news.

Sorry for my slow response, and thank you for your visit.
I'm really happy to hear your feedback!

Okay, first question was asked by Joseph, about the shortwave
feaver in Japan in the 1970s. The boom was mainly among young
boys, ranging from 10 years old (I was eleven at that time) to
14 years old - elementary school to junior high school. With
portable shortwave radio, boys listened mainly Japanese language
program of overseas stations. This is because those boys could
not understand any foreign language, and there were many Japanese
programs offered by BBC, DW, HCJB and Radio Peking, to name
a few. However, main purpose was to collect QSL cards, rather
than enjoying the program itself. The boom lasted for several
years, then the next generation kids had less interest in shortwave;
instead they excited about computer games, which was quite new.

Dan San,
Fortunate enough to get a Panasonic RF-2200 receiver in reasonably good condition, it arrived yesterday. Only problem is the telescopic whip was damaged and don't know where I can get a suitable replacement.

In any case I was up till very late last night like a little kid again playing with this radio. For such a vintage set I was most impressed by the MW DX performance of this radio. Money well spent. Now I need to locate the Sony ICF-5900W Sky Sensor.

The Ramsey CW filter AF-1 is interesting, you should look also at the Vectronics VEC-821K Super CW filter - Also a Kit. 80, 110 and 180Hz, 60 db down 1 octave from centre frequency, 8 poles of active IC filtering using cascaded low-Q stages. Centering frequency of 750Hz abd up to 15 db noise reduction with a built in ANL circuit.

Very good and interesting site!!!

I own a SBE SB-36 and am looking for a Manual for it and History on it. I know it was 1965-66 vintage and Frequency read out, and also it has an RIT circuit and about 250 Watts output. Receive audio is the best I ever heardfrom a Tube and Electronic Hybred.
It is Chrome and Black very impressive.

I really appreciated the beautiful shortwave systems you have. Lovely.
I didn't know there was a sw boom in Japan in the 70's. What did they listen to?

My home page is way out of date.

I recently obtained an Echophone Commercial EC-1. After replacing the filter capacitor and one burned out tube is places excellently. I obtained most of my information about this receiver from your restoration project. Thanks for the good work!

Enjoyed very much you your beautifully illustrated feature on radio restoration. I have a Benmar 555a which is just magnificent on the AM Broadcast and Beacon bands. Would you know where to find an instruction book for this or service manual so that I might align it for accuracy? Great reading, will tell fellow radio buffs about your presentation.

I love the picture and information you posted regarding the Echophone EC-1b. I've got one too (I've got the older EC-1), and it's my faverate old radio.

I found your articles on the Sony ICF 5900w of great interest, this was my first portable transceiver. I am still looking for one today as the one I had was sold, I would like to keep one now due to fond memories of the past. I also own the ICF 5800.

Nice page!
