My location is a very poor one, as previous experiments have shown, yet the set performs excep- tionally well and works even better when used in locations that are known to be at least average and will give a receiver an even break." Radio Digest has given Mr. Fournier's receiver some very thorough tests and is convinced that this set possesses sufficient merit to present it to Radiophans at large.
