Of course it IS a problem - it may be too late. Most of other radios make it possible, so it's probably not a top notch science anyway. 73, Sinisa YT1NT, VE3EA
It is a myth that TenTec radios can deliver full power to unmatched loads. Absence of SWR foldback is far from being sufficient for such a goal. 73, Sinisa YT1NT, VE3EA
Speaking of theory, no power can be delivered into a dead short, and very little power can be delivered to loads significantly smaller or greater than the rated load. This is basic circuit theory, an
Yes, it is, and a fairly large transistors are used, along with some protection. Observe voltage/current limitations given in the manual (13.8 V, 250 mA), and do not forget the protection diode at th
A 1:1 current balun works only in limited cases when its impedance is much higher than the load impedance. Given that most commercial baluns have difficulty reaching 500 Ohms, the application is limi
A dipole cut for EU SSB band can be used on CW with two coils of ~2 uH each inserted in series with wire legs. Coils can be safely short-circuited for SSB by ordinary small 16 A relays. Tested in YU
Following the recent discussion of open wire feedlines, I've compiled a 3-page PDF with some useful details. The 70 KB file can be downloaded from: http://www.geocities.com/va3ttn Basic definitions a
The tables and the formula they are based on (may be found in ARRL Antenna Book) are valid for any length of line, and any degree of loss, provided the line is uniform. I was wondering just the same
Hi Martin, Actually, I did the math with intention of proving that the formula is wrong :-) The formula represents just a limit of accumulated loss caused by an infinite number of two-way reflections
One more word of caution: most plastic ladder lines use copper clad steel conductors. Such lines are only suitable for low SWR applications, and in this respect they behave more like RG8 coax than li
It's interesting to note that the foundation work, J.C. Maxwell's "A Treatise on Electricity & Magnetism" used metric units exclusively back in 1873. 73, Sinisa YT1NT, VE3EA
