You are bidding on a nearly brand new CommRadio CR-1 Receiver.  I accept PayPal so you can use your credit card for payment.  Shipping to the US via Priority Mail (typically 2 to 3 days by air) with tracking and insurance is $14.99. 

I have had this radio for about a month (originally purchased October 26, 2013).  It is a great receiver on shortwave and includes 2M, Weather, Air, Marine, FRS, GMRS, Public Service, etc. that you typically don’t get with a shortwave radio.  I have to sell this because I blew my budget last month.  The original receipt is included in case you need it at some point for warranty purposes. 

Direct from Comm Radio shipments are delayed until January because of high interest.  This auction enables you to get a nearly brand new receiver now for the holidays instead of waiting.  This radio was shipped from the factory with the current latest firmware as of November 27. 

Includes Receiver, USB Charging / Updating Cable (requires AC adapter), Internal Battery, User Guide and Box. 

  • The CR-1 is a small, low-power, ruggedly constructed radio receiver that is finding a niche in the world of SWL’s (short wave listeners) and amateur radio enthusiasts alike.
