Just bought Yaesu FL-2100Z Linear Any issues?	Reply

Hi! I just bought a Yaesu FL-2100Z linear, the one which covers 160,80,40,30,20,17,15,12,10 meters and has two 572B tubes at 2400 volts DC in it, Are there any issues with respect to this particular model? I already have a Yaesu FL-2100B which is the same except it only covers 80,40,20,15,10 meters, no 160 meters and no WARC. The FL-2100B works fine and I like it.

Not sure about the regulations (and limitations) in your country, but in the U.S., Amateurs (any class license) are limited to 200 W. on 30 Meters and and portions of 75-80M, 40M, and 15M. [In the U.S., refer to §97.313(c)] So you probably wouldn't want to use the amp on 30M.

Power Restrictions for Canadian Hams below 30 mHz 2250 watts DC Peak Envelope Power for any mode of SSB 1000 watts DC as measured at the transmitting tube anode. 750 watts RF output for CW and other modes. There is no mention of power limit made about the WARC bands, so we can run our full legal limit (1000 Watts DC Input) on these bands. Please note our legal limit (except for sideband) is about half the legal limit in the States, however the Canadian Legal Limit does not vary across the HF Spectrum. I recognize that 30 meters has a lower power limit in the U.S., so do the American novice sub-bands to protect the novices. My Yaesu FL-2100Z will run the legal limit 1000 watts DC on CW which is the mode I want to run, and will do it 160 - 10 meters, including WARC bands 160,80,40,30,20,17,15,12,10 I guess this linear is hard to find because it was a match for the Yaesu FT-101E which didn't cover the WARC bands. I will be using My Icom IC-706mkiiG which has general coverage transmit (see http://www.mods.dk) and easily covers the WARC bands.

Canadian law does not recognize sub-bands. Mode allocation is by bandwidth - we are allowed six kilohertz bandwidth or below on all bands below 10 meters, with the exception of 30 metes where we must be one kilohertz bandwidth or below (i.e. CW). Since I operate exclusively CW on the HF bands, I can run the (Canadian) legal power of 1000 watts DC Input from my Yaesu FL-2100Z on all bands my FL-2100Z can cover, and it covers them all from 160 meters through WARC and 10 meters :) There is no reason for this Canadian amateur to want a bigger amplifier.

Off the subject of your original post, but I didn't know that about Cdn regulations. How do they recommend measuring "DC input power" for PEP? 2250W PEP DC input power seems an unattainable measurement to me; for one thing, you'd need to peak sample and store or display both instantaneous plate current and instantaneous plate voltage, which will be heading in opposite directions usually. Is there a standard they recommend for actually making this measurement? WB2WIK/6

Also off-topic: I used to have a Heathkit SB220 and it had two meters, Voltage and Current, because of this regulation. When on SSB I ran it so the meters indicated 1000 watts input (of course the peaks were much higher) The FL-2100Z like the SB220 has two meters, Voltage and Current. When I draw 500 milliamps from the voltage doubler power supply in the FL-2100Z, the voltage drops down to around 2000 volts, although it is 2400 volts key-up. This is a legal limit linear for CW operation, and CW is all I do on HF so I'm happy. I understand you can run 1500 watts RF output in the U.S.

Yes, we can run 1500W PEP output power here, except on 30m, in some Novice subbands, on 60m, and in some parts of other bands that have to protect military operations near specific locations. Since output power is what causes interference, and not input power, this makes a lot of sense. I was just wondering how they expect anyone to measure "PEP DC input power" in Canada...doesn't seem like a measurement most of us could possibly make. WB2WIK/6
