The 6600M provides a way to use CAT control for the slice with TX focus. Hooking this all up was a breeze with a null modem cable between 6600M and the RF2K+. The main consideration is how long the relays take to switch. With a PTT lead time of 10 ms it would take 13-15 ms (10 + 3-5) till High power goes out, and 3-5 ms would be lost of the signal.If the amp is in CAT or UDP mode, it does a short RF sensing routine, that takes about 3-5 ms.This is very similar to a simple Kenwood-style CAT protocol that can also be used. The amplifier can receive UDP packets that tell it what frequency.With a PTT lead time of 10 ms it would take In this mode, the amp runs a comprehensive RF sensing routine, that takes up to 15 ms.Basically, this is without any rig control and have the amplifier figure everything out.I have played with CAT, UDP and Universal. The amplifier has multiple rig control modes. A “good-citizen” value would be maybe 10ms. PTT lead time before RF is not needed by the amplifier, its likely more needed by transceivers and antenna switches.If the amp has to switch band relays (transmission about to occur on a different band), it takes about 15 ms.Understanding the equipment betterīefore putting this all together, I had to learn and understand more about PTT, PTT lead times and how it relates to all three pieces of equipment at play. No affiliation to any manufacturer referenced in this blog. 1 AMP 2 radio switch by 4O3A Diagram from 4O3A’s websiteĪnd by the way, the should be doable with any other CAT controllable radios and amplifiers.

That allows not only to share one antenna with 2 radios, but I can share one amplifier with 2 radios/VFOs. I found this neat antenna switch called “ 1 AMP 2 radio switch” and made by 4O3A. My next question was: Do I really need 2 amps for this? Or even run on two bands with high power. For SO2R and in High Power category, you want to run with high power and also do S&P with high power. Time-consuming enough that it pretty much prevented a semi-competitive contest entrance. This worked great, however, was cumbersome to do during a contest. I like the fact that the amp can be tucked away and can be fully remote controlled from any computer device on the network.Īfter working for a few days with the new toys, I realized that I could use the amp for both slices by swapping ANT1 and ANT2 on the radio and switching my 6 x 2 remote antenna switch appropriately.

Putting the amp together was easy and took me about 1 day. The amplifier came in form of a kit and produces legal limit of power on all bands below 6 m. The radio is built with SO2R in mind (2 ANT outputs, receive filters for contesting bands). I am proud owner of a Flex 6600M and a RF2K+ kit amplifier.
