Today I mated the 55G-1 Reproduction by Dave W3ST and my 51S-1 (which Peter K2LRC rebuild) I also put the 55G-1 into a RM352 (Rack mount by NovexCom) which I have stacked in a rack. Looks nice now. The removal of the feet required me to remove the chassis from the cabinet to get to the two front nuts to reduce the height of the front leg. (I would recommend that the front legs be taped to make it easier to remove) After getting the mechanical assembly completed I proceeded to get the electrical connection/disconnection done.
This requires that you cut a jumper in the 51S-1 and connecting three connectors with RCA plugs. Following the directions in the manual (which is very well done and published by Ted Craven, W5USI) I connected the three cables (The three cables have over sized RCA outer shield this required me to use a pair of pliers to crimp the outer ground connection on the RCA plugs to make a good connection on the RCA jacks on the 55G-1 and 51S-1.
After all the mechanical and electrical work was done it was time to play with the unit. I must admit the tune up work that my friend Peter K2LRC did on the receiver was super great. The receiver is very sensitive and does a great job . The addition of the 55G-1 enhanced the lower bands a lot and it also reduced the cross-modulation on the broadcast band above 500kHz. I have always wanted to hear some broadcast stations from Europe and with the 55G-1 it did the job as I heard a French station. I also was able to hear some other CW stations that I would never hear with a 18 HT vertical antenna.
If you enjoy the 160 meter band and cruising the LF bands for some real DX, I would recommend that you get your 51S-1 tuned up for best reception) and put a 55G-1 into the system and enjoy the difference that the 55G-1 reproduction unit makes. Great job to all involved. (Editor.s Note: There are few 55G-1 reproduction units available. Contact the CRA at collinsradio@comcast,net.
