I'm glad you watched the video. The Sony ICF-SW23 was sold in 2009 as the final version of the ICF-SW20, and was a fully analog portable radio with a double superheterodyne circuit configuration. It's extremely portable, but the shortwave reception performance of the radio on its own was a bit lacking. However, when using the included reel-type auxiliary antenna, I was able to hear overseas broadcasts at night very well. It had a very simple structure with only a sound quality switch and volume adjustment on the left side and no other functions, but it made a great contribution to reducing the weight of luggage when trekking. I remember that even with such a small radio, I was able to hear a lot of broadcasts while on the mountain. It looks similar to the CR-200 you mentioned in your comment, but the contents are completely different.

@@May_happiness_come_to_you_777 amazing to know!! Thanks for the info i have recently found my intrest in radios and boomboxes! I can too hear some broadcasts from other countries as i live in finnland am radio here is been closed since 2000s so it has to be from other countries i have heard also russian anyway thanks for the info have a nice day

I'm glad you watched the video. Unfortunately, production by PALSTAR has already ended. However, if you have the materials and a soldering iron, I think it's possible to make one yourself. The product is very expensive, but if you make it yourself you can probably make it for about 1/10 of the cost. The key parts of production are the use of high-quality ferrite bars and Litz wire, equally high-quality variable capacitors, and the design of low-loss amplification circuits. It's not something you can do right away, but it's a lot of fun to research and make it yourself, so why not give it a try?

I'm glad you watched the video. I was able to hear 7MHz LSB communications, but I was unable to hear any aviation/marine radio or high-band USB communications at the time I filmed. Solar activity is currently at its peak, which should allow radio signals to be picked up from greater distances, but results will vary depending on the time of day, antenna and receiving location. Perhaps the antenna was chosen incorrectly.

Я рад, что вы посмотрели видео. Используемая антенна представляет собой проволочную антенну длиной около 8 м. Это старое радио, которое осталось в доме моих родителей, и оно до сих пор хорошо работает и прекрасно звучит.

Я рад, что вы посмотрели видео. QTH - Токио, Япония. Я использую антенну AOR SA7000. Если вы находитесь на открытом воздухе, вы можете получить достаточную чувствительность, используя только встроенную выдвижную антенну, но из-за индивидуальных различий в самой радиостанции не все 2001D (2010) имеют такие же характеристики, как показано в этом видео. Однако если радиостанция и антенна хорошо подобраны, вы должны получить отличные результаты.

@@May_happiness_come_to_you_777 Спасибо за ответ

Ой ладно вам! У меня такой приемник. Много чего на его ловлю и вытягиваю дальние радиостанции

Copying the look of old Kenwood hf sets.

I am glad you watched my video. This radio appears to have excessive gain when a high performance antenna is connected. A few feet of wire antenna seems to work better.

I'm glad you watched the video. When I bought this, I tried various things to see if I could improve the sound quality of my relatively inexpensive portable shortwave radio. While the end result wasn't a huge success, I was at least able to make the audio on a weak signal stand out, so I think it was satisfactory. It especially contributed to easier listening on SSB/CW.

I'm glad you watched the video. The IC-R8500's RF gain control has only three selections, -10/-20/-30db, with only -20db available for frequencies below 500kHz. There was a time when this was a topic of discussion in Japan, but I believe it was due to the manufacturer's design philosophy. The functions and operation feel are similar to those of a stationary receiver, but when using the actual device it feels like a handheld device with enhanced scanning functions. Here in Japan where I live, it is popular among those who enjoy aviation radio and as an introductory model for SWL, and even though it has been discontinued, it still fetches high prices on the second-hand market.

@@May_happiness_come_to_you_777 Yes, they definitely command high prices on the used market. Interestingly I've read many complaints about the three position RF gain selector/control of the Bearcat DX-1000, which is much older. Yet no one complains about the lack of a RF gain potentiometer on the front of the IC-R8500. The AOR 5000/5000A/5001D all seem to only have AF gain and squelch controls on the front. Yet no one complains about there being no RF gain control, BFO, and other "knob" toys one would find on something like a Hammarlund HQ-180A. Maybe the desire for such "control knobs" as died away over the years?

動画をご覧頂きましてありがとうございます。 思えば鉱石ラジオに始まりボートアンカーも様々な一物達に触れてきました。 そのどれもが皆素晴らしい設計思想を持ち、実機の構成もラジオ少年が見たら心躍るものばかりで興味が尽きません。 このR390A/URRもそんな心くすぐる一台です。 本機は現場でかなり酷使された様子で、内部の汚れ具合や破損修理状況、金属のすり減り具合等を診るに過酷な環境にあった個体である事を想像できます。 全てのパートを動画でご紹介するには膨大な時間と手間暇を必要とする為、この動画もかなりの部分を削除編集してのアップロードとなりました。 私ももうかなりの高齢ですので、修理のご依頼等は承っておりませんが動画でその手助けが出来るようを願っております。

早速の返信ありがとうございます。 私も中学生の頃にBCLに嵌り、還暦過ぎた頃から当時手の届かなかったスカイセンサーやクーガー等の受信機を収集し始めました。 現在は真空管のハリクラやハマーランドも愛用しています。 但し電子工作の技術がない聴くだけの人間ですが… 貴殿のお返事承知しました。 ありがとうございました。 今後もブログ楽しみにしております。 次第に

Estou feliz que você assistiu ao vídeo. I'm a grandpa who lives in Japan. O 390A do vídeo foi adquirido no final da década de 1970, mas a graxa das engrenagens endureceu com o tempo e demorou muito para ser limpa. Estava cheio de poeira porque fazia muito tempo que eu não tocava nele porque estava ocupado com o trabalho, então dessa vez dei um banho especial nele.

The noise of icom R75 is quite loud. It is recommended to buy an R71e in good condition.

I'm glad you watched the video. It is certainly unfortunate that the number of shortwave stations is rapidly decreasing. It is likely that the number of shortwave radio stations will continue to decrease in the future, but I hope that pirate stations will emerge to make up for the decrease.

I'm glad you watched the video. If you disassemble the lamp switch, you will see that it has a momentary part inserted into it, so by removing that part it can be changed to an alternate type. It's not very difficult, so please give it a try.

@@May_happiness_come_to_you_777 Thank You very much for Your answer, I'll try it for sure. I'm glad I did find Your video because I was about to design a flip flop based circuit to obtain the same functionality with electronics; this way it will be faster and easyer. I already have the leds for dials illumination. Thank You again. Luca

@@May_happiness_come_to_you_777 Hi, I opened up the radio, I've seen the plastic insert in the middle switch assembly, I did open the assembly and removed the insert but it is not enough, a small slot remains open in the pcb and the switch lever does not find nothing to lean on , so I had to modify the original insert by dremeling it and adding a small piece of plastic. Maybe a replacement insert could 3d printed to perfectly fit the hole. Anyway , my switch is now an on off switch. I did also replace the two lamp bulbs with leds . Thank You for Your help ! Luca
