    80m Dipole problems

    I had a problem tuning 80m on mine, tried different lengths of feed line. You do not need a resonate antenna on 80m, mine was around 25 ohms at 3.550mhz, my tuner didnt like 25ohms.... I ended up lengthening my dipole to an overall length of 140' which moved my resonate frequency to around 3...

    Imax 2000 only 7' off ground??

    I give up on the picture. Every other picture I linked worked but this one. I even deleted it and uploaded it again. As you can see its just above the roof line (hyperlinked it). Years ago we had local CB competitions where we would drive up to the highest hilltop we could find and host a...

    Imax 2000 only 7' off ground??

    Welcome to the club my Imax is only 15' or so to the base. I have a 140' doublet up 40' feet or so. Antenna modeling shows it to be the perfect height for vary usable lobes from 80-20 meter bands. Looks how hard the 12 gauge wires are to see. You can easily use thinner gauge wires and a...

    Imax 2000 only 7' off ground??

    My 5' Firestik has never failed me making contacts in the mobile...... Many times its was better than the base on skip from 500-1000 miles. Im assuming the shorter skip preferred the higher takeoff angles?

    RM Italy KL-7505 or KL-503?

    Whats your radio setup like? I have a KL503 it works ok, the wattage is nowhere close to advertised. If I remember correctly is was a 150 watts max for keeping the waveform linear. I also did some mods, it wouldn't work on SSB out of the box.

    FM CB in US?

    Just think if everyone ran FM you wont have people on channel 6 wiping out the whole band!

    Fan dipole questions..

    Just feed it with ladder line and forget about it! 4 Bands can get tricky, 3 seems to be ok.

    Can this be fixed?

    +1 for good grounding. I had one a with a bad transformer bite me, It shorted to the case. Lesson learned.....

    Fan dipole questions..

    I dont live in a park but my neighbors are just as close. I use a inverted V 140' doublet (max length i can fit), the ends are tied to the neighbors fence. I also have power lines in my back yard, where is your transformer? Most parks are all low voltage insulated wire..... I would recommend...

    Fan dipole questions..

    I would string some thin gauge wire up in those trees no way anyone would notice! I saw your other thread what tuner do you have?

    Thinking of ditching the HF antenna tuner.. doing a fan dipole??

    I walk by a kegorator, my wife gets pissed If I pee in the back yard but its so convenient!!! The dog pisses out there so I do it out of spite......

    Thinking of ditching the HF antenna tuner.. doing a fan dipole??

    I payed around with spacing on a few programs. It seemed to me the closer the elements the better. I would just use a twin lead wire (speaker wire) and call it good. Before you go with a fan I would do a 80m doublet. Mine is 140' long (keeps the tuner happy) 45' high at the feed point and ends...

    Mosfets and "power" claims

    Every radio tunes differently. Some radios you can drop a mosfet into and get 35+ watts. Others might have little to no increase in wattage, even if its the same model radio. If your radio has lower wattage, a lot more time and effort has to be put into tuning the "Pi network" and there is no...

    Base New Imax wont tune 11m....this sucks

    Try adding a 3' jumper to the length of your antenna coax and see of it changes. Also have you tied tuning and or checking the swr and the antenna feed point? My Imax isnt a perfect match either.....

    Galaxy DX-94HP from Bells... Backwards Swing

    With a %100 modulation on an AVG reading watt meter that looks normal to me.... Only way to tell the correct modulation levels is with a scope.

    High / Low AM adjustment

    I would not run more than a 5 watt carrier out of that radio. Both adjustments affect each other. Higher carrier could be hurting your performance. Buy a amp if you want more power.

    Pickup truck mounting

    I wish it was easy to model a vehicle. I have done some testing with a friend. My puck mount preformed as good as a mag mount with a counterpoise..... Im starting to believe antennas being 6' off the ground really dont make much difference in mounting. I have also done blind antenna testing (on...

    Mobile microphones. Best value for dollar spent.

    I bought one for my mobile. The gain seems a little low. I changed out the mic gain resisters I get full modulation and zero background noise when driving. Its a really good noise canceling mic!
