Interesting history behind these receivers, germans buying parts from USA during WW2 to build nearly a clone receivers 😳 I like a lot the construction of these tuning mechanics... Seem to be very robust and precise. Thanks for this video. Hugs 😊
Helge, thanks so much for your efforts preserving these important historic artifacts. I’ve been fascinated over the last 18 months with your efforts. So intriguing to wonder what specific role each might have played in the war effort!
Thanks for making these videos Helge, My only chance to see many of the German radios. And you provide more detail than most videos. Great to see your radios in action. N8SH
Hello, I have several National HRO receivers, they are my favorite receivers, you have to replace those leaking capacitors/resistors and of course perform RF and IF alignment. On my Website I have a Northern Radio used in Alaska during WWII, of course its a National HRO rebranded. Thanks for sharing!
helge gracias, tu video es genial, tengo un hro 5ta1 de 1945 con su house dog y speaker original,y sus 4 bloques de bobinas ,funciona muy bien..73s de cx3et...
I very much enjoyed your video about the KST. I have been a HRO receiver owner and enthusiast for many years. I am interested in the story of the National Company selling HRO parts kits to Portugal/Germany. Please direct me to more information about this. What year did this did this occur? Thank you for your very splendid radio site.
Thanks for the comment. I have received information from various books and FB groups. Hard to figure out where now. What I found out myself was that many of the mechanics and the screws inside have inch measurements. Interesting to hear if you find out more about this.
Hi I found some relics from ww2 in the sea and I think one of the things I have found is a part belonging to some German radio equipment, I would really appreciate your help trying to identify this item and you obviously know your stuff when it comes to German radios!!! Any help would be appreciated Thanks !
Sir I watched the entire vidio.I have one HRO M Receiver.Its sensitivity is not good these days.Could you please give me the voltage chart of the Receiver or at least the HF oscillator Grid voltage and 6B7 plate and screen voltages.Iam a Radio amteure Call sign Vu2GAN 73s
Very interesting Helge LA6NCA, in particular your hypothesis that the USA have also sold the mobile radio to the "Portuguese", I have also checked my S / N 0815 apparatus and I am convinced of the correctness of Your observation. 73 de Federico IZ1FID
Thanks for the comment. I see you have many nice videos on your channel. Interesting that you find the same things in your radio that I found in mine. I see that you have serial number No. 815, I have No. 344 and No. 418 At the Radiomuseum I see No. 871 Do you think 1,000 were produced? 73 de LA6NCA
@@LA6NCA Helge LA6NCA I was thinking about it yesterday while I was commenting on your video, if the Germans have also bought the cabinets it will be difficult for them to have made more than 1000, maybe we could start a survey on the Facebook group to find out the serial number of the surviving specimens, this would give a more precise idea.

Great sounding radios

Thank you for writing such nice comments.
Beautiful working Radio. I have one but not working. the sound is very good.. Mario VE3WPZ

Thank you for video Helge. I did not know that Germany had cloned these HROs. The KSTs look like they have nicer to use frequency tables.
Yes, I like the German version best.
The frequency reading is easier.
Very interesting, thank you.

The KST I have does have bandspread coils...but the bandspread is not for ham radio bands!

For me HRO sounds a bit nicer then German copy.
Yes, interesting comparing them.

Unfortunately, I no longer have it.
I mostly collect the German radios.
So I have given these HRO radios away.
