ARRL to MITRE: Don’t Mess With HF Ham Bands

MITRE Corporation headquarters
The MITRE Corporation has an FCC experimental license to test wideband communication techniques on a variety of HF frequencies between 2.5 and 16 MHz. 

The ARRL Letter reports that ARRL Chief Counsel Chris Imlay, W3KD, has sent the company a letter asking that it either structure its tests to avoid HF amateur bands or, at minimum, to provide advance notice of times and frequencies of planned transmissions. 

The ARRL’s concern, according to the Letter, is that “with the operating parameters proposed, it will be impossible to conduct your tests … within the Amateur Radio allocations and … avoid harmful interference.” A further concern is that due to the nature of the transmissions, “amateur licensees will have no way to determine the source of the interference or know to whom they might complain.” At press time, there had been no response from MITRE.
