Summary of Contents for Ham radio HK5A

  • Page 1 HAM RADIO CENTER...

  • Page 2: Battery Installation

    For transmitters employing grid block keying, connect the RCA Phono Connector to the grid jack on the back of the HK5A. For cathode or solid state keyed transmitters, connect to the direct jack on the HK5A.
  • Page 3 The second problem, that of RF interference in the keyer may show up as steady or uncontrol- lable keying of the transmitter. If the HK5A keys normally while the transmitter is turned off or is being operated at reduced power but is erratic with maximum RF output, the problem is caused by RF interference.
  • Page 4 Where a severe RF problem exists it may be necessary to install several ferrite beads on each of the leads leaving the HK5A. To install the ferrite beads it will be necessary to unsolder the leads from the appropriate jacks in the HK5A, thread several beads over each lead and resolder the lead to the jack.
