The build quality is good. However this 600mW (28dBm) module uses the same PA (RTC6659) as the 200mW (23dBm) module. So the output cannot achieve 600mW.

verry good module,my 2nd purchase. stock SPI mode work well. see attached picture to disable SPI mode and enable A or E band. If you put pine1 of the RTC6705 to the GND you disable SPI mode and enter A band(get ~430mw@ CH8 5725mhz ) , binary encoding the ch1/2/3 pin to select the 8 possible channels of band(pin to the ground=1 logic level) (ex: ch3pin to the ground=> CH4 in binary table of band channel). Cutting pin 3 &4 of the RTC6705 enable E band(bascam band) and get ~620mw@CH4 5645mhz(lower channel in 5.8 band) but it heat a lot (provide a heat sink) , ~320mw @CH8 band E 5945mhz. PA input can be controlled by 0 to 5v pot. PA 0v=>125mA@5v PA 5v=>780mA @5v Jay
