The Model R-1 was the first commercial broadcast receiver produced by Northern Electric. The R-1 first appeared in the Nov. 1, 1922 Nortern Electric Radio Bulletin No. 1000. The R-1 was a Non-regenerative TRF circuit. The first R-1 receivers were not equpped to handle a variometer to provide regeneration. Later models had a pair of binding posts in the upper RH corner of the front panel that interrupted the plate circuit to provide a feedback path.

Even though Northern Electric had access to the Armstrong Regenerative License from at least 1923 on the company chose to market the companies first broadcast receiver as a Non-regenerative set. The R-1 pictured in the November 1st, 1922 Radio Bulletin No. 1000 didn't have an external method for adding a plate variometer to provide regeneration. Later models had two binding posts in the upper RH corner to allow the addition of the Northern Electric R-20 Variometer to provide regeneration.
