    26OD004 :) I've been quite active lately with all the nice conditions we've been having, been hanging around on .385 in the afternoons for the US DX, usually on the triple nickle any other time. Had some great openings to Pacific/Asia for the past couple of weeks, can't remember it being this...

    Thailand - 11 meter

    nice contact indeed, 153 div has been very strong in the UK for the last couple of weeks, managed to work a couple of stations over there recently. I was listening to the states this afternoon on 385 LSB, and to my surprise I heard a 153 div station calling for USA on the back of my beam, so he...

    MRF 477

    I've got a couple laying around here, they are also used in the older President Lincons/Uniden 2380's

    FILTER

    In reply to Robb, yes you're right, adding a ground plane kit to the Imax along with a choke will do the same thing as I suggested. As for who's responsibility it is to solve RFI problems, if you are licensed and you own you own home, then maybe you can just shrug off neighbours RFI probs and...

    FILTER

    Some good points made by all, even sitting in the closet with a tin foil hat on, as long as you can't reach your CB anymore, lol. What you can do at your end is remove the Imax and get a ground plane antenna, add a coax or ferrite choke to prevent any CMC's, which could be causing a problem...

    Official HAM License?

    Think you will need to get your callsign issued before you get your "official" license, that can take a few weeks, at the moment all you have is a "pass certificate" to show you passed the exam. I think you might need to send your "pass certificate" into the FCC to get issued with your license...

    Building a dipole - tips?

    No, the only difference you will notice if you use insulated wire is that the antenna will be a little bit shorter (but only a few inches). Not sure what you mean by "centre wire" tbh You can use almost anything that is an insulator, personally I keep the families old toothbrushes...

    your favorite CB myth , lies and legends .

    There might be an element of truth to that one Booty; If an amp is producing high levels of harmonics (which is quite possible when overdriving the snot out of one), the antenna will not radiate the harmonics as efficiently as the primary signal, and reflect part of the harmonic content back to...

    Palstar PS 30 only giving 15 Amps

    Hi WW, The 706 is fine, it gives 100W on my PSU and the same when in the car. The PSU is a very common one over here, sold under a few different brand names I think, countless people use them and have no problem running a 100W HF rig on them. PSU is this one .... Palstar PS 30 The person I...

    Palstar PS 30 only giving 15 Amps

    Hi, just been given a Palstar PS 30 to repair, I can't find schematics for this anywhere, anybody have, or could point me in the direction of some please? The PSU will only deliver 15A (should be a 30A peak supply), which equates to my 706 only doing 70W on FM when set to full power...

    Why adding coax changes swr

    My first guess would be an insufficient ground plane. Forgive my ignorance, but it's mounted on your RV, which I think is a big mobile home thing, is this made of fiberglass by any chance? How and where is the antenna mounted?

    the truth according to Firestik (get a drink and a snack , LOL)

    Just for the record, could I make it known that I too, am in that 1%, lol. It does make me laugh when we have quiet prop days here, because all the locals start calling on 27.555 "CQ ground wave", when really they just want someone to talk to.

    What are these pcb components?

    Robb gave you a good breakdown of what they do in that particular radio, but I don't think he read your post properly, lol. The ones in yellow are tunable inductors (coils), just the same as the other coils that you see on the board there. The difference being they have a slug inside the coil...

    ICOM 706

    WARC are the relatively newer bands, 12M and 17M. like 385 posted the power levels for VHF/UHF were increased as the newer models were released. One thing I know was changed (can't remember if it was in the MKII or MKIIG it got fixed) was the design of the VHF PA. If you ran the radio at...

    Sirio Gain Master - First report

    Either you are missing the point, or I am. What Booty quoted was "Robb told him a dB is a dB, in both RF and audio terms, a dB is a unit of measurement", and that is completely correct. Just because it takes a 10 fold increase in electrical power to produce a "perceivable" doubling in volume has...
