Thank you Michael Watterson for what you saw what saw. Now I have a question similar to yours: BKS237 and BSK237 is one and the same model or not? On my model there shild labeled BKS237.

King regards

Hallo Mr. Korniienko.

In the literature are found both spellings.
Look in comments to the German text of the model.

Regards WB.

Hello Mr. Bauer

Reading is good, but the fasts that we have, are stubbom things. At RMorg we have 10 positions company Braun (3 pades), which presents seven real models BKS...or BSK... Of these two models

BKS237 and BKS237K have Schild(data sheet). One model BKS36, there is a photo without the nameplate. The remainirg four models have shild BSK... Ie there is no single model,called BKS...undBSK... Andin the scheme presented inthe same way there is no RMorg. Braun serious company (with a famous last name) could not rearrange the letters on the just so I know the answer.

 But first, I"d like to see the answers opponents are.

Regards

Oleksii Korniienko.

as referenced in the page: Lange-Nowisch calls it BSK 237. Please always use the literature references. They are meant to provide background information.
General remark: To have no access to ref.literatureis not an excuse, sorry. In such a case search/research is due.

Right or wrong, we must care for every of spelling.

I owned a 1938 model (sold it 10 years ago) where the label displayed one way, while thelarge sticker quoted the other one...

both way apply to the same model, and we do not know where this ambiguity happened. Consequently we care for both ways to be on the safe side. Ther is reasonable suspicicion that it happened to more than two models.

On the other hand there is no prrof of non-existence as long we would know 100% of all such models built. the few pics and catalog entries are not sufficient to waive the strong suspicion.We better leave that as it is. It does not harm, is not misleading (explained why in remarks), and it even prevents from uploading separate models which in fact are doublets.

Dear administrators-editors,

In this post I posted photo BKS237 model with a range of wavelengths MW and LW. Why are you posted pictures BKS237K receiver with a range of LW, MW and KW? Besides. there are differences in the design of radio boxes:

BKS237 - back panel is not removable

BKS237K - removable rearpanel

Various sizes of box:

 

BKS237 - 350x260x150 mm

BKS237K - 400x300x190 mm

Different connection to battery:

 

BKS237 - spring terminals

BKS237K - another way to connect

This data is sufficient to present a model Braun BKS237 as a new model for RMorg.

Kind regards,

Korniienko Oleksii.

I think all the BKS237K with SW are from Valery Gromov

What is difference with the Koffer-Super BKS237 F - BSK237 F that has KW?

Anyway, I moved all the photos Valery uploaded to the Koffer-Super BKS237K no doubt he loaded them to the wrong model by mistake as the filenames have the "K"

Cases like this you can use the admin-en address at radiomuseum.org

 

Thanks.

What is difference with the Koffer-Super BKS237 F - BSK237 F that has KW?

Dear Michael Watterson

The answer to your question with his coments:

1). The list shows the status of the cap lamp KC1_4pin with no photo real model, and the base schema

type can not be determined.

2). In the look, Lange-Nowisch, Band 2 preserved "Berichtigung," which shows that "Braun237F" in

nature does not exist. So, administrators need to decide for themselves.

Kind regards

Oleksii Korniienko.

That suffix "F" was obviously a typo in the first edition of Lange-Nowisch, which was corrected in the second printing (4th ot 8th thousand) to read "K".

Der Zusatz "F" ist ein Druckfehler in der Erstausgabe. Die folgende Auflage (4. bis 8.Tausend) ist bereits korrigiert auf "K":

  5 Dear Michael Watterson From this a typo in the post RMorg "Koffer Super BKS237F-FBSK237" appeared non-existent model, where the fivst scheme BSK237F-typo, and the second scheme BKS237-real model presented me to another post. Conclusion: The post"Koffer Super BKS237F-FBSK237" should be removed completely. Kind regards Oleksii Korniienko.

Dear Oleksii,

if there is a typo found in literature or at hardware, we keep that as a model with appropriate remark.

Why?  If we would not, then sometimes in future somebody would find it and (not knowing of being a typo) would propose it as a new model. And the poor admins would have to start again research and explanations or might even overlook.

That is undesirable. Since we are not only a listing of existing models, but an encyclopedia, we must also inform about such errors.

The"phantom" must be kept. OK?

  1 Can someone send me a picture of the orginal knobs of the BSK 237. I am missing some knobs and want to make them by my self. Espccially the tuning knob with the little switch knob I am looking for. Has someone these knobs for selling? The KK2 socket is of a IO (8 pin) type instead of the P8 type. Is this orginal or maybe replaced?
