Began picking up UNID milcom on 5723 last couple of nights. This freq is not on any of my known Milcom frequency lists, so any ideas would be appreciated.
Hearing sporadic alpha-numeric identifiers tonight beginning around 5:00z: Kilo, Juliet, Echo, Echo-Charlie, Delta so far tonight. The frequency is mostly silent but patient monitoring is rewarded with these sporadic check-ins of one sort or another, accompanied by UNID digital bursts. Hearing a few rounds per hour.
