Im Gegensatz zu Radioempfängern für kommerzielle und/oder militärische Zwecke und den frühen Empfängern für Morsezwecke nennen wir hier Radio bzw. Rundfunkempfänger. Aber: Gemäss internationaler Sprachregelung führt der Radiokatalog Band 1 alle Empfänger mit aktiven Bauteilen als RADIO. Wir unterscheiden hier ebenfalls nicht, ob mit Röhren bestückt, hybrid, mit Transistoren oder/und ICs.

Looking at the models www.radiomuseum.org displays the total of 2300 models made by Zenith. To our present knowledge the radio model CRL Reg (see picture) or the radio model Zenith Long Distance, both from 1920, are the first radios made by Zenith Radio Corporation, Chicago, Illinois. I hope we soon can find a picture for the "Long Distance" model.
For 1921 we list the radio model Zenith Regenerator with a picture. But we don't know more models for 1921.
In 1922 Zenith made the models 1-M (1M), 1-R (1R) and 2-M (2M) and only for 1-M we are missing a picture. Above this text you find the link to the model 1-R because this article is written by first accessing the model page and then using the link "Add information to model or forum text".
I post this because at the moment Google lists our makers page for Zenith Radio Corp. as number one (from 312 000 hits), followed by this model 1-R. This gives us a good chance that a guest might send us some information about models we carry without pictures or schematics by using the contact form . This can be found on each page of the morethan 200 000 pages RMorg displays by clicking into the bottom link "Contacts".
A small group of members achieved the most complete radio catalogue about Zenith radios which shows at the moment 452 Zenith models with pictures from 1920 to 1937 and another 451 Zenith radios with pictures from 1938 to 1943. Well, during WW2 the civilian production stopped and was resumed in 1945. From 1944 to 1950 we list 155 Zenith radios ith pictures and from 1951 to 1960 we show 497 Zenith models with pictures. From 1961 to 1999 we count another 237 Zenith models with pictures. In other words we display 1792 Zenith models with pictures . This is 78 % of the total of 2300.Zenith models with data and ost often also schematics.
I know that the later models are not yet in the state we would like to have them and also that our goal for a full radio catalogue for the USA is not met yet. But we know that it is the most complete picture gallery plus source for schematics for the USA and some European countries.
We radio collectors should have a complete catalog to find out the designation for sets where we miss any designation - because this can best be done with a complete radio catalogue. I hope we can achieve this goal with our more than 4400 members , including about 450 from the US. Only our active collectors or radio lovers who care can achieve this. Thereis always a need for help - and we also help in the forum by answering questions on a high technical level - adapted to the ability of the one who has put the question.
I know: Our undertaking is quite challenging but we came already quite far by having also well organized programs which let us do a reference work with a lot of integrated data for a radio like tubes inclusive photos, technical papers, base connections, standard schematics for the tubes (in case there is no schematic for the radio), possible substitiutions etc. One can find radios easily with the same tube line up etc. Radiomuseum.org (RMorg) is based on a certain spirit for helping each other and not just profitizing.
Have you got a Zenith radio for which we have no picture?
