My FooBar-300 radio shows itself as China_radio-100 once I opened a saved image of it, it’s that normal?

Since June 2016 Chirp support a feature called radio aliasing, and it’s used to represent a clone of a real radio in the user interface for the users convenience. This is more a trick in the guts of Chirp for the developers but it has a quirk the users need to know about.

h2. The problem.

Some radio manufacturers – mostly from Asia – are assembling some re-branded radios by request with custom names, at the end this radios are no more than perfect clones of a previous existing radios from the Chirps point of view. The perfect example for this is the Baofeng UV-5R with all the [[Baofeng_UV5R_Variants]].

This is no problem at all for using the radios in the day to day work on it’s features and performance, but for Chirp developers it’s: we need that every radio has it’s own and unique identification code or ID to get it clearly identified.

Before the alias feature implementation you have to know before hand that your Juentai JT-6188 Mini was just a clone of the QYT KT-8900 and so on with other vendors/models.

This has brought a lot of confusion and problems on the user side, the site issues and the user mailing list are prof of that; with users asking about support for specific radio models that are no more that just clones of others.

h2. The fix.

The first approach was to educate the users by putting comments on the [[Supported_Radios]] page about the clones and the right radio to select, and answering issues on the site and emails on the user list. That proved to be just a partial fix, as newcomers keep asking the same questions all over again (Who read the manual anyway?)

Then, in a debate in the developers list, Dan came across with this alias feature. with this feature developers has the option to register the radio clones as what they are: clones (technically aliases for a real radio) and allow to show them on the users interface as it’s own VENDOR/MODEL for the users pleasure and peace of mind.

h2. A quirk you will notice and a workaround.

This alias feature has a issue we can't fix in software: when you download and image of a radio that it’s a clone and save it, that image will became the real radio once opened again in Chirp and you will found yourself asking a similar question to the one on top of this page.
30 1 Pavel Milanes
31 2 Pavel Milanes
For example, if you read and save an image of a Juentai JT-6188 Mini, when you re-open it from the file in your hard drive, you will found Chirp telling you that this image is for a QYT KT-8900, not the Juentai JT-6188 Mini, this is completely normal and you are safe using it for your clone radio.
32 1 Pavel Milanes

It’s confusing, we know; but remember that Chirp’s team always encourage to keep a few images for every radio and do not cross use them with other radio models or variants. For that reason we have implemented also a suggested naming schema on the saving of a img file to cope with that.
34 1 Pavel Milanes
35 1 Pavel Milanes
Once you want to save a copy of your radio data you will find Chirp is suggesting you to use the {vendor}_{model}_{date}.img schema, for the above example you will receive the suggestion to use this: Juentai_JT-6188 Mini_{date}.img
36 1 Pavel Milanes
37 1 Pavel Milanes
So when you look for and old image file of your radio you will always know that this image was for that particular radio vendor & model as it’s stated on the file name, this will help you with the mentioned quirk in the aliasing feature.

So far we have just a few clones or aliases listed on Chirp, we hope other developers jump to implement it for the remaining aliases, specially for the Baofeng UV-5R huge family of clones, we know its’t a huge task and will take time.

So far this radios are implemented as clones or aliases:
44 1 Pavel Milanes
