I have a 259 MFJ .. bought used, at a fair price.. way happy ...like the 2m coverage, etc....... I put together a "kit" to take on the roof .. like, bigger 12V portable battery, connection adaptors,
Hi Steve. I have the CIA-HF, an Autek RF-1 and previously owned an AEA SWR-121. The Autek is good, takes relatively accurate measurements, but has some serious drawbacks. It is hard to read, incessan
As a 'newbie' I can say the MFJ-259b is an awesome tool. The manual does an adequate job of explaining how to use the analyzer to read Z, cable loss, etc, etc, etc... but NOT what these things are. T

Tom must've croaked when he saw that. I just retain the good advice I've gotten and pass it along when I can. Seriously, I have no engineering qualifications, but I've owned the Autek RF-1 for years
asking Pete, I have both a 259 and a 269. The 269 is vastly superior to the 259. Much easier to use, more functions, more "stable" readings, many more measurements. Definitely worth the extra $100!
The MFJ-269 has a 12bit A/D converter whereas the 259B only used 8 bits to digitize the detector voltages. From what I have heard this gives the 269 more accuracy at high and low values of impedance
Is the MFJ the only analyzer or is it just superior? What other measuring devices can be used if the budget does not support the MFJ269 plus stuff. (Close to CA$800 landed) (Or close to 3/4 gross mo
the monthly Hi Chris, There are several other analyzers and they have all been discussed in e-mail posts in the last few days as well as on eham.net. Someone posted that info as well. I suggest you
One can make quite accurate impedance measurements using the "three meter" approach at very low cost. Essentially, you hook a capacitor (chosen to have an impedance around 50-100 ohms at the frequenc
It is even easier to make an impedance measurement using a series resistor. I have used this technique for years. All you need is to be able to make a reasonably accurate SWR measurement. Then you ne
I based the price on a price from MFJ catalogue and a quick calculation by thumb. Most of the hams here just double the US cost for approximate landed cost. I shall do one a little more carefully. Fr
14.5% tax is pretty bad. Seems like it might be worthwhile to take a drive to meet a "friend" somewhere inside the US border who happens to have the unit. Your "friend" can still buy it for $319 or l
Chris this may be an eye opener. Maybe this calculation will settle the discussion Original cost $434.80 US Conversion to TT$ -= 2739.24 Import duty (20% on C.I.F.) = 547.84 Stamp duty (12%) on c.i.f
Frank, Your analysis just confirms how unaffordable radio "toys" are for a large segment of the world population whether it is caused by war, governmental economic mismanagement, extreme taxes, or an
I kinda like the ideas presented. This maybe the more precise one though more difficult. The measurements can be taken and insrted into a program. Jim: You mention a "... RS232 DVM, an RS232 controll
