QRP Linear, The Outcom OPA202 Wideband, 160w	Reply
by SCUBA on March 18, 2007	Mail this to a friend!
Recently acquired a Outcom OPA-202 wideband linear amp at a "swap meet." I have yet to put it in service, meanwhile I'd appreciate hearing from any other OPA-101 or OPA-202 users. The OPA-202: 20 amps Driving power AM 1 thru 7.5 watts, SSB 2-25 watts. Freq Range 7 thru 30 mhz. Output choices: 4 watts in - SSB: 30, 60, and 180 watts out 4 watts in - AM: 100 and 160 watts out If I have to get a low pass filter, I will, but I could just use it mobile and not worry about filtering the output. ;) Maybe it already is filtered, I dunno for sure. 73

This is a Texas Star obsolete illegal CB amplifier. It has NO filtering and will not meet FCC specifcations for use on the amateur bands. Allen

Dang!!!! Bummer! What a let-down!!!! Fortunately I didn't pay much. Guess I could build a homebrew linear and gut the Texas Star case and use the case. Or, I could just sell it to a trucker, maybe. Sheesh, maybe I could house a spark-gap transmitter in the case. Will the FCC ever legalize (properly built) QRP linears, or will things just stay this way forever? Well, thanks for replying, even though the news is less than favorable. Guess I better go lick my wounds. Suggestions?

There are qrp amplifiers that are legal, they meet the FCC requirements. Gary n2vww

Hi Gary Hi Allen The amp was in a box of parts and radios I bought real cheap, all I wanted was an SWR bridge and the rest of the stuff was incl in the deal. Also got a 50 watt Pierce Simpson radio that caught on fire when I plugged it in. Wierd, so I took it outside, opened it up, plugged it in again and a coil was smoking and burning up. Strange. I could either give the amp to a CBer or use it for parts, or just gut out the case and use the case for a project. The inside is rough looking, looks like the rosin seeped out from the solder joints. It powers up ok, but I really don't plan to hard wire a FT817 to it; no telling what it might blow back thru the coax. It'll probably look real nice under a CB'ers dash board. Not just here, but the more I tell people about it, the more I get beat up; so i guess I better qualify what I say/write about. 73, Jack

Hi Gary, I didn't mean to say "beat up," I got cautioned by everyone I told about the amp; - cautioned not to use it. I have found some excellent kits out there (in addition to Ramsey kits); although I may wind up going the FT-897 route before the Yaesu sale price expires end of April. 73/Jack

Heavens sake don't give the amp to a CBer. Most hams want to rid the world of that junk. Use it for parts to build a project or two. You will like the Yaesu, I have heard a few on the air and they do a good job. Gary n2vww

Take it with you when scuba diving and forget to bring it back. Illegal means illegal for anyone! Allen

Hi Allen, Underwater Linear, yeah, sounds good. I can place it on a reef or something, photograph it, send the photo to a magazine. I probably won't leave it in Davy Jones' Locker 'cause toxins might eventually get released as the sea water causes components to degrade over time. Thanks for the idea! Jack

I don't know about FCC certification, but Tokyo Hi Power makes a very nice 5 watt in 100 watt out 160 - 10 meter amp, including WARC bands. This amp even automatically band switches along with the Yaesu FT 817. This is not a CB amp but is a very high quality unit intended to be used with HAM QRP rigs. I am sure it will meet FCC specs. Whether or not they have gone to the trouble and expense to get the amp FCC certified is another matter. Tokyo Hi Power is now advertising in HAM magazines and some of their amps are available in the US. I know many HAMs using this amp with Yaesu FT 817 and similar rigs. Most bought their amp directly from Tokyo Hi Power in Japan. This is a simple matter and it will arrive at your door in about a week.
