    Help me identify this strange antenna. . .

    That is odd, the antenna must have some sort of loading mechanism besides the simple base loop. Without a photo is hard to visualize the antenna. Does it resonate anywhere when it is fully extended? I have a few of the older ARRL handbooks with the ads in the back from the 30's, 40's, 50's...

    Help me identify this strange antenna. . .

    Since you have an analyzer, is the antenna resonate anywhere?

    Unfortunately, as you suspect, it sounds as though you had a shorted/gassy tube(s). Glass tubes like the 3-500z do not store well over long periods of time. Did you flip both switches when you turned it on? One is for the amplifier power/filaments, and the other controls the High Voltage. If...

    LEGAL LIMIT SOLIDSTATE AMPLIFIER

    Since Econco will not rebuild the Eimac 8877, it too is a non-rebuildable tube. So it comes down to $600 for a Chinese tube or $1075 for an Eimac. I believe that I wll keep on using $600.00 tubes that are giving good service. I have no need for a larger tube, new or rebuilt, all I can legally...

    Last I heard was Econco was not rebuilding the 8877 becuase it "was not cost effective" I've never heard of a rebuilt 8877 or see one for sale.:confused1:

    I certainly understand where you are at. I agree that the 1200 is a more durable tube over the 1500 when it comes to its ability to sustain abuse of the grid. However, the point I was making is I believe that a lot of the bad publicity the 8877 gets is not so much the design or the tube...

    I am aware that the 3CX1200 has twice the grid capacity of the 3CX1500, 50 watts vs. 25 watts. I also know that the 3cx1200 requires a significant higher level of drive to obtain the same amout of output power due to it being a less efficient tube. I typically pull about 7 mils of grid...

    I must be lucky, I've hit a Chinese made 8877 multiple times by accident with 200 watts of drive and it is still doing what it supposed to do. However, my amplifier does have a lot of protection which forces the the amp off line. Nevertheless, there are thousands of amateurs using the 8877...

    A few 10 meter repeater questions

    10-10 numbers are issued by ten-ten international 10-10 web site You can collect numbers for points/contests/etc. to get awards. Mostly, it exists to help promote activity on 10 meters, therefore it is an exclusive awards program for 10 meters only. You can earn a 10-10 number by contacting...

    A few 10 meter repeater questions

    That is because most of the hams you hear sounding awful on 10 meters are mostly ex-cber's or new ops. Most newbies don't realize that the ALC meter is your friend. Keep it turned down to the acceptable ALC zone and your audio will usually sound fine unless you are getting RF or some other...

    Tokyo Hi-Power did the same thing at Dayton in 2008 with the 2.5K model. I think they ran it at 1.8KW for the entire weekend. The only problem I see with the Tokyo Hi-Power is custom made transistors they use, if I had one of those amps, I would buy two sets of spares just in case...

    Hey Booty, Now you know better than to challenge the Professional CB Radio Operator Gods, after all they are the self appointed experts who know far more than anyone else on the planet and can argue down every known proven law of physics ever discovered with their time proven (I saw it on my...

    Yep, and an 8877 does not cost $1250. You can purchase a Chinese made 8877 for around $600.00 and it works just as good as the higher priced Eimac. I have a Penta branded 8877 that came factory in my Alpha, 35-40 watts in = 1500 watts out. 73

    I think it is B.S. too, but I am not allowed to say on the other board because anytime you challange one of the self proclaimed radio gods about their OBVIOUS B.S. claims they get real offensive, then the moderators on that board have to come to the rescue. I always laugh when I read their...

    On another board I read occassionally, a gentleman was seeking advice about an antenna issue whereas his swr is inconsistent, sometimes it is 1:1, sometimes it is 1:5 and somtimes it is 2:1 In response, one person stated: "skip can, will, and is possibly affect your swr. being over the past...

    swr goes up when amp is used

    Not funny at all, when the amp is on stand by the input circuit and amplifer is bypassed and your RF is put straight through to the antenna. 73

    Low Power on 10 meters.....?

    I found the article on the Daiwa meter. The only daiwa review I could find was the Daiwa CN-101L, here are the numbers at 100 watts SSB, at 2 mhz the meter read 30 watts; at 14 mhz the meter read 30 watts; at 28 mhz it read 30 watts peak. The reading at 1 kw on voice were: 2 mhz, 900 watts...

    swr goes up when amp is used

    Forget the analyser. Do it the way before the MFJ 259 existed. Use you radio to key the amplifier. This is what you want in line. Radio - SWR Meter- Amplifier-Dummy Load. Put your radio on 10 meter CW, adjust the drive from the radio to about 10 watts. Tune up the amplifier for max output...

    Low Power on 10 meters.....?

    QST did a review of a few meters a while back, I believe the Daiwa was included in the review. I will see if I can dig it up later this weekend. 73
