Ordered a FoxDelta AAZ-0713A antenna analyzer kit from the vendor in India. Arrived is less than 10 days.
The AAZ-0713A is a basic antenna SWR analyzer operating from 1 thru 30 MHz. Analysis functions and data acquisition are performed thru a Windows software tool and a USB or Serial interface to the analyzer. If using USB, the analyzer is powered by the USB +5.
The kit packaging quality was very good, all components labeled in individual little ziploc bags.
All SMD components come pre-soldered, no cost savings option to buy the kit with the SMD components unattached.
PCB trace and pad quality appeared fair to good, silk screening is OK, no errors. It's not a top grade PCB, but its absolutely not junk either.
Sub component quality appeared very good, measured the caps and coils with my LC and they were all very well within their tolerances. The DDS circuit is one of the 9850's so popular from China. The controller is a PIC.
Assembly instructions I grade as poor to fair at best. I had no problems finishing the assembly by cross referencing the good quality schematic, BOM and finished circuit card assembly pictures. However for someone who has little technical circuit design or assembly experience this kit could be a frustration. There are NO step by step assembly instructions a-la Heathkit.
Completing the circuit card assembly and conducting some pre-powerup checks took about 2 hours.
The free Windows software from FoxDelta for interfacing to the analyzer seems to work quite well thru the USB interface. Had no problems whatsoever installing the tool or interfacing/recognizing the device (Win7).
The software has a calibration routine which the utility asks to be run each time the utility is opened. Cal routine takes approximately 10 seconds to complete.
There are a number of analysis options in the utility: sweep resolution, spectrum sweep limits, multiple sweep plots, plot presentation types and some others. I finished building the thing one night before writing this review and have spent a total of 30 minutes playing with the functions so have not come close to wiggling all of the knobs yet. Did run some sweeps on my home brewed hexbeam and 40/80 meter trapped dipole, very good data which jives with plots taken with MUCH more expensive analyzer instruments.
For $35 shipped from India I think the kit is a genuinely fantastic bang for the buck. Tis a Shame the unit cannot readily accommodate 6 and 2 meters as I'd happily pay double the $35 for that!
Product is in production.
