ImprovementsOvertheAR-3300 The Ranger AR3500 is an improvement over the AR-3300. whiCh I reviewed last year, in the following ways: Instead01using one set of momentary-con- tact switches for increasing or decreasing fre- quency, there are now two banks01switches under the display. T

It pretty much cancels just about all mobile noise. By pushing in the mike gain knob. you can now activ

The AIT control, called the clarifier, seems 3073AmateurRadiO .June. 1989 The Ranger AR-3500. to have been opened up a bitoverthe pre- vious model and offers somewhat broader tuning.

8、These changes may seem small, but they make the Ranger AR-3500tarmore pleasant to use. TheANland noise-blanker circuits are especially welcome,asis the change totwo banks of switches to moveupand down fre- quency. Stillthe Same The areas that havenot changedare still the same ones which we noted las

No automatic mode is implemented al- ter several seconds, asis commonly done with other momentary-contact devices in theelec- tromcs world. The CW mode is still

And, last but not least. the price. The sug- geted retailonthe AR3500 has come down dramatically-from$600to$350-tomake it truly competitive with the other popular 10m mobile rigs on the market today. Given all the plusses, the AR-3500 is worth a look by the serious 10meteroperator.III
