Update 2021 : The JC-3s tuner is not in production at this moment.

We will investigate if it is possible to start producing again.

Highlights:

1: This tuner tunes almost everything. On the low bands your wire should be a little longer for better performance

2: Super performance due to smaller capacitors steps.(9pF)

3: 3,5 - 52 Mhz. ( 160 meter possible with long wires but not supported)

4: Direct control from most models of Icom and Kenwood

5: This tuner you can use on any radio with the control box (included)

6: Extremely good performance for mobile operation of small balcony antennas.

7: 50 EEprom memories (so no battery inside)

8: Also extremely useful for mobile and portable HF operations
