Balanced Line Tuner Plus
The BLT is a simple Z-Match tuner that works from 10-40 meters, designed by Charlie Lofgren for NorCal. Charlie is probably the number one man in the world when it comes to Z-Match Tuners. The tuner tunes balanced feedlines, thus the name "BLT" for Balanced Line Tuner for the mnemonically-challenged among us. Charlie originally designed the tuner to go with the SMK-1 and the NorCal Doublet for 40 meters, but when he delivered his design we found it tuned other bands also. With the NorCal Doublet, it tunes 10 - 40 meters. We rate the tuner at 5 Watts, but it will probably be safe at 10 W. The BLTPlus comes with several modifications including the coax/balanced inputs, and the Dan Tayloe N7VE LED SWR indicator are built in, and is an absorptive bridge, so you won't fry the finals as you tune. Great design, by a great designer. All parts for the tuner are included, including the case. It uses polyvaricon caps. We have upgraded the tuner to now include all of the connectors and switches needed to tune balanced lines, coax and long wires. There is no need to do the mod as on the older cases. This kit has had the mods incorporated into the kit.

"Got mine finished last night and never have I had a kit that I put together work the first time. The BLT tuner worked great. Just had the diode in backwards but that was easy to fix. Doug has made one of the best manuals for a kit that I have seen. Photos are great and sure help you keep on track. This kit would be great for the first time builder. It was great to see the LED go out on 40 meters. Doug you have set the standards for a user manual. A big thanks!"
