PTT Buffer - Linear Amplifier Optocoupler Isolation Time Owned: 0 to 3 months.
Here is a quick summary of a very very well done product made in VK for amp keying line isolation, EXCELLENT QUALITY, seen of more expensive products,
translucent blue project box, excellent colour printed top label, this map key isolation unit has TWO RIG OUT PUTS
available in KIT or Completed form, Very very good value for those not able to source the bits, WORKS 100%, Extremely well done mini circuit board construction,
the exercise was to test and use this isolation device in conjunction with the Australian made EMTRONDV ES-4
MULTI RADIO, MULTI ANTENNA, SINGLE AMPLIFIER application, once inserted in the ES-4 keying line, ALL RIGS connected to the ES-4 are protected on the output,
if NO ES-4 in line, this great little product has TWO radio Keying isolation ports.
requires 12v dc,
peace of mind even if the amp has low current keying line, no physical hard connection adds to the safety if a tube shorts etc,
great gadget
