HF Beacon and FM beacon modes for 2M FM fox hunting

Straight key operation bypass (limited keyer functionality)

Iambic practice modes including a progressive mode which increases/decreases speed

Built in speaker with stereo headphone jack for private listening

Positive OR negative transmitter keying maximum of 200V/120mA/300mW

Battery Installation (Assembled units)

Batteries are included.  

There is a jumper on the back of the unit to disable power during shipping or long term 

storage.  Use a pair of tweezers or surgical clam to move the jumper to the ON position. 

 To replace batteries, remove

the 4 screws on the bottom of the unit.  Insert 2 AA batteries observing the polarity as shown on the battery holder.  
Replace the panel and 4 screws on the bottom.

OPERATION

Plug your straight or Iambic key into the KEY jack.    With the key down adjust the volume as needed.  If using the 
headphone/SKPR jack ALWAYS turn the volume control fully counter-clockwise BEFORE plugging in.  Then with 
the key down adjust the volume to a comfortable level.  Plug a transmitter into the XMIT jack.  Refer to the Mini-Yack 
operations manual for commands and usage.
