Crt 9900 V6

The 9900 V6 is sensitive to impedance mismatch. For 10 meters and 11 meters, a robust antenna like the Sirio Performer 5000 or Wilson 5000 is recommended. You must use an SWR meter (the radio has a built-in one) to tune your antenna to below 1.5:1 SWR before transmitting. Failure to do so can damage the final transistors.

RX and TX NRC (Noise Reduction Circuit) with 5 adjustable levels to eliminate background static.

The latest versions have significantly increased the output power and stability compared to earlier models. crt 9900 v6

Given the history of 11-meter usage, AM performance is vital. The V6 revision has significantly improved the AM carrier stability. Unlike some competitors that drift off frequency after 30 minutes of AM operation, the 9900 V6 maintains lock.

For local comms and repeater use on 10 meters or freeband, the FM mode offers crystal clear, static-free audio at the cost of range. The CRT 9900 V6 includes a dedicated FM squelch circuit that is fast and accurate. It also supports wide and narrow FM deviation settings.
