FlexRadio 6300 XVTR power increase greater 15 dBm

DL7MST Member
Hello Om´s

does someone know to increase the XVTR Power out greater than 15dBm limit?
For an Transverter operation i need at least 20-30 dBm.
Otherwise i have to use the 2nd Antenna out....

any ideas?

    Hi Matthias

    The maximum RF out of the XVTR port is actually 10dbm and there is no way to increase it inside the radio.  

    Which transverter are you using?

    The Ukraine Transverters used to only ship with attenuators, he now offers them assembled without attenuators boards as well as with them. For example, here is the pre-built, ready-to-use 2m transverter without attenuator on eBay: https://www.ebay.com/itm/144-to-28-MHz-ASSEMBLED-TRANSVERTER-WITHOUT-ATTENUATOR-2m-144mhz-146mhz-VHF-UHF-/222662833996 He also used to provide instruction on request in how to bypass the attenuators. Hope this helps

    Agree - i used one for a while without an attenuator. The Flex handled it well.

    I have one without the attenuator, but only drive it with about 10% of the transverter port available power. You don’t want to run the transverter at full output anyway, reports are that they start to get dirty at more than about two Watts output.
