Hi, I would like to hear from anyone who has used a Flexradio 6300 barefoot at 100w in low power RTTY contesting, especially if you run a lot. The reason is some of the reviews in eHam.net mention th
Ken, I have both the Flex-6700 and the 6300. I also recently acquired a Maestro. The serial number on my 6700 is #29 so I am an early adopter/user/owner of the 6000 series. I use the 6700 for RTTY co
No xcvr should be run at more than 50% power for RTTY. Stan, K4SBZ "Real radio bounces off the sky." _______________________________________________ RTTY mailing list RTTY@contesting.com http://lists
RTTY contesting is effectively 50% duty cycle, at least until you need to respond to someone who wants a ragchew. I have run RTTY contests on a K3, and all kinds of FT1000 at full power. I have also
There are two issues, and I don't see either addressed completely in the FLEX documentation, but I didn't see any warnings either. They are: 1. Can the transmitter run at 100% power for extended peri
Me too Jeff, no problem with any xcvr that I've had. Nick, w4gkm No xcvr should be run at more than 50% power for RTTY. RTTY contesting is effectively 50% duty cycle, at least until you need to respo
I disagree. If you are into 10 minuet rag chew transmissions maybe... For contesting the duty cycle is pretty low. 5 seconds transmit and at least 10 seconds receive is less than 50 % duty cycle. We
100% duty cycle is full power output at all times. No time to cool off... Never switching the transmitter off. A broadcast transmitter is 100% duty cycle. This is not what RTTY is unless youre a broa
Maybe instead of saying "No xcvr", maybe you should have said "some xcvrs". I always ran my TT Omni VI at full power in many RTTY contests with no problem. I even called TenTec and asked if I needed
At least one of the online specs for the IC-756 Pro III (which I own) says RTTY is rated at 100 watts with 100% duty cycle. Probably representative of all the late model Icoms. There might be IMD or
For what it's worth: I have run my 6300 in contests at full power for extended periods and my feeling is it gets too hot. The case will become uncomfortably hot to the touch. Heat is the enemy of ele
Yaesu 2K/950/5K/9K is the same - can run full power. For RTTY contest duty cycles, there is not a specific limit due to thermal dis at least specified by Yaesu. RTTY rag chewing where the key-down ti
For contest QSO's I have run a Yaesu FT1000MP and an Elecraft K3S at full power for many hours straight with no noticeable heating or other issues. John KK9A-W4AAA Stan, K4SBZ "Real radio bounces off
I have run my FT990 at full power in contests for the last 20 years. The probe I clipped to the heatsink shows a higher temp when leaving the rig in RX for a while than when I am running in a contest
Many rigs, like the FT 990 have a duty cycle rating. From the 990 manual: "Duty cyde: 100%@100watts, 50%@100 watts (FM & RTfY,3-minute tx) " I have not located such a spec in the FLEX literature. --7
And 3 minutes of continuous TX in an RTTY contest is a VERY long time :-) Op 3/06/2016 om 21:59 schreef Michael Clarson: Many rigs, like the FT 990 have a duty cycle rating. From the 990 manual: "Dut
The Flex 6300 can run at full power indefinitely with 100% duty cycle modes. This is in the tech specs and has been confirmed a few times in the official Flex forum. 73 de Guy G4DWV/4X1LT ___________
