    Superscanner antenna Yeah!!

    Stuff like this antenna stopped being available when the CB antenna safety regs came out. These days it seems people are getting around that little problem. What other bands are you thinking about?

    Sirio engineers making antenna's from scrap materials?

    There are a few very fair minded people who's conduct in the face of disagreement is to be commended. You know who you are. Thanks. NAV IMHO is entitled to a bit of poetic license considering all the nitrogen laden banter from the pro-Sirio camp. I would love to see pictures of the...

    gainmaster vs i10k a quick test with locals

    So antennas with low angles of radiation have reduced local coverage and increased local coverage. OK.

    gainmaster vs i10k a quick test with locals

    Very interesting. What angles would you say work best for 5, 10 or 15 miles? Thanks.

    BINGO. Same goes for magic 43 foot ham verticals and SteepIR antennas.

    Mr Coily's Base Enforcer Antenna

    If adding radials made your sig go up 2 S-units something must be really wrong somewhere. How about telling the same folks you added 8 more radials and see how many more S units you get.

    4 pill driving 16 pill amp might kill woman

    You need lockout, tagout. You should have the key to the station's padlocked disconnect before climbing. If they won't comply call OSHA.

    Hey all, I want to build an AM transmitter.

    That looks really basic and the oscillator in a can kind of makes it a black box deal. It also looks like it may also phase modulate some. Depending on what you want to do and learn there are probably better designs out there. What are your goals for this project?

    YOUR Opinion On Free-Banding

    One important part missing is Marconi was sure shortwave was useless. Since it was deemed useless, experimenters were allowed to play there. Had Marconi realized the utility of higher frequencies there would not have been hobbiest radio.

    ready to pull the trigger on a Kenwood TS-440SAT why shouldnt I?

    FYI Most TS-440s with the VCO-5 glue problem can simply be left turned on all the time. The heat made by the rig is enough to keep moisture out in a lot of cases.

    To any and all S/S amp designers

    Hambone rigs using pairs of 2879s typically make 125 watts P.E.P. maximum. Each 2879 is good for 50 - 65 watts P.E.P. before you hear from your neighbors on the band. Yes, I know this is a whole lot different from CB stuff. 8 2SC2879s and 600 watts out would be right on the edge of...

    tilting a yagi?

    +1 A 160 doublet @ 65' fed with good balanced feedline and a decent coupler will smoke a 3 el. tribander in 2 directions. Most put wire antenna up and hope for the best without knowing where the lobes will work. Someone claiming wire antenna cannot keep up with a tribander must be...

    Tube amp help...

    A manual would answer much better than I. I don't know the capability of this amp aside from maximum recommendations listed for the tube type. The spec sheet is failry clear. Is says 60 watts P.E.P. as a linear amplifier. 60 watts carrier on FM would probably be pushing it unless the bias...

    Tube amp help...

    The small tube's number isn't important. It's just there to operate the relay. Here's a tube spec sheet for the amplifier tube. 60 watts out is P.E.P. under intermittant key down with the wind at your back. http://tubedata.tubes.se/sheets/084/8/8637.pdf Does the meter on the amp say...

    Tube amp help...

    Is there a manual and or schematic anywhere on the www? What tube is that? 5894? The smaller one is for the RF sniffer as you suspected. If the thing is rated for 50 watts AM carrier it ought to do pretty well on FM but might benefit from a bias change.

    Tube amp help...

    Obviously some of those meters are not going to work at VHF. Use your 50 watt radio by itself to qualify them. If the plate isn't designed to glow and it does glow due to problems it may have been damaged. If the tube is blushing it is not loaded properly or maybe the bias voltage is too...

    Tube amp help...

    With low drive power and the load set about halfway, tune the plate for peak output on a sensitive wattmeter on a low scale. Try the load next. Alternate back and fourth between these taking a break after every 20 seconds to let the tube cool off. Tune the grid tune control for max out of...
