does anyone know for sure the power output of the tentec delta (580)? on one actual advertisement it lists the delta as a 200 watt transceiver. other specs i have read rate it at 100 watts. does anyo
I had one <580> and the output was 100 watts. Paul Gates, Kd3JF john ferro <foxbat426@hotmail.com> wrote: does anyone know for sure the power output of the tentec delta (580)? on one actual advertise
100 Watts output. Most likely, the "200 Watt" is a reference to DC power input, not RF power output. does anyone know for sure the power output of the tentec delta (580)? on one actual advertisement
There was a habit some time ago of "power inflation" in marketing by quoting the DC input power rather than the output power. This seems to have seeped into various websites documenting the gear who
Maybe 200 watt input, but more or less a 100 watt output rig. Mike, K9MI -- _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailm
In the old days, there were no reliable methods to measure power output. Watt meters didn't exist that were in any good unless they cost more than the transmitter. In fact the FCC restrictions for po
It wasn't habit; it was U.S. regulations. Input power was calculated, not output power. Lots of folks who entered amateur radio since the change in regulations seem to think it was always thus. Dave
John: Yes the Delta is rated at 200 watts......input. Typical output can be expected to be 100 watts on the lower frequencies to about 80 watts on 10M. 73 Bob, K4TAX -- ______________________________

Actually, this was a regulatory issue. Until sometime in the 1980's the FCC specified that the DC Power Input to the Final Amplifier stage was the Power of record. In other words, the actual output p
Actually, 375 watts carrier with 100% modulation, should give the 1500w max output. WA4TT _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contes
soooooooooooo 375 audio and 375 carrier equals 750 watts peaks above and below the base line making 1500 Watts of actual PEP , right ? It always sounds nice if you have the right detector and a broad

Correction: At 100 percent modulation, AM Operators are are permitted 375 watts of Carrier Power, not 250. Here's a link to a May 1995 QST article that addresses the subject. http://www.arrl.org/tis/
In the days of link coupled outputs and open wire feeders, rather than standard impedance coaxial cables, it was easier to measure it this way. Another detail was that you could run up to 900 watts
As a living fossil I can weigh in on this one. Until the advent of the Bird wattmeters, which none of us youngsters could afford, there was no common way to measure output power of transmitters. Inpu
