Yeah, it's like comparing a AK-47 with stamped out parts to a AK-47 with actual machined components - it works but I aint thrill with sticking my clip into it. BTW, heckler & koch 416 is my weapon of choice with the modified AR-15 as very close second.

Thanks for the facts - I think I will stick to using the cobra 138 or 29 on 11 meters. Thx, Joe

Yeah, I already have a fund for that - every time I 'rub one out', I put a dollar in the coffee can. So far I have accrued $472,123 Thx. Later, Joe

I am tinning the radiator and 8.5 inch extension segment as we speak - actually I have delegated that task to my semi-retarded son and I just hope he keeps the business end of the Weller gun out of his eyes (and ears for that matter). I think the 'Merlin' used the same design as well. I would...

Sounds like some sound advice and I didn't know you were the 'paint it pink' dude so disregard my 'meth lab' remark; I'm a new yorker and having a sharp tongue goes with the territory. Gonna try 107.5 ~108.5 inches for the radiator and see what happens. Thx again, Joe PS Watch out where the...

So it's the paint, eh? I think you're on to something there. You see I painted it w/gold spray and evidently gold spray paint is an excellent conductor; I might as well have used the street lamp in front of the house as the antenna and some zip cord as a transmission line to achieve the same...

Thx Thanks, I appreciate the SWR antenna transmission line edification, as does my back. Humping that thing up and down is a real bear and wreaking havoc on the ole' spine. When I say a relatively 'flat' VSWR, I mean 1.1 : 1 (or less) on the tuned frequency but not exceeding 1.5~1.6 : 1 on the...

Radio Shack's RG-8/U is the same as any companies' RG-8/U (solid center conductor and 97% braided shield), just twice as expensive. I am still using some of the several hundred feet I bought in the late 70's (sold at $.21/foot - cut at the store from giant spools) Be that as it may, coaxial...

Hey Now, I have been experimenting with a 1/4 ground-plane w/ 4 drooping radials. After three attempts I am puzzled as how to achieve a reasonably flat VSWR across the frequencies I frequent (~ 11 - 10 meter). I'm trying to perfect it in anticipation of a skip-full dog day nights of summer. I...

Hey Now, I have converted an Alinco DX-77 by removing jumper 'D' and it now TX and RX from 1.5 MHz to 30 Mhz ( including the 11 meter band (CB). If I open the case and switch hard-wired PC board switch from 100 watt to 50 watt and then implement the low power feature provided on the console of...

I am currently building a sloping 1/4 wave ground plane. I have a Cobra 148 modified to about 28 MHZ( operating range 10 to 11 meters). What frequency should I use per resonance, i.e. for what frequency should I cut the length of the radiator so as to maintain a acceptable SWR across the board...

Mod for Cobra 148 Modifying the Cobra 138XLR is straight-forward and fairly simple if you have relatively steady hand and a low-powered soldering iron with a tip that has been ground to a small point. It is easy to unlock the units 858 Phase lock loop chip and to modify the clarifier to slide 1...
