We introduced the KN-Q7A SSB transceiver kit in October 2011, and it was a big success. Thousands of kits were sold in the past years, then it was discontinued due to parts shortage. Now, we bring it back with a few modifications. We also newly added 15-meter called CS-15V. Here, V in CS-xxV is for VXO. There is no DDS, MCU, or anything else digital. All analog, all traditional.



The IF crystal filter pass band flatness is improved with a better impedance matching. Thus, the receiving and transmitting audio sounds noticeably better. And the insertion loss of the filter is greatly improved as well.



The MC1350 replacement is a tiny module of a dual gate FET. The gain is lower, the gain control is counterclockwise [of course, you can modify it back], but it is loud enough for the speaker microphone if you are using a full sized antenna.
