[MRCA] R-105/ARR-15 mod?

Jeep-

I have that configuration as well at my QTH, set up for channelization using
the ART-13 remote control.

Do you know what in what aircraft configuration the ARC-25 was used?

The mod, in general, appeared in 73 magazine in the 1960's.  It is/was an
unnecessary hack job, I believe. The ARR-15(  ) can be used even with its
very broad IF. An outboard Q-5er works quite well. There is an internal cw
audio filter of some slight usefulness. The mod brought imbedded mode
functions to the front panel. The only mod one would need to possibly do is
attach fil and B+ to the dynamotor pins via a rear panel plug as the organic
mating connector is unobtainium.  The dual PTO design is interesting. My
ART-13/dual ARR-15 (ARC-25) setup now in ops at W1NZR.

Hi all, I was browsing ebay and came across this ARR-15 and noticed someone
ham-mered the front panel with a column of switches down the left side.

https://www.ebay.com/itm/166778324274

 

then I saw another one just like it, but better done!

https://www.ebay.com/itm/115721014547

 

I got to wondering, was this a common mod? Anyone know what it is for (maybe
switching attenuation in/out?) or was this an official mod or something?

 

Thanks
