Apparently Hell has actually frozen over. We now have a full desktop client for Smart SDR for Apple macOS systems. It is pretty well known that Flex Radio has the best remote capabilities of any radio available today. This is an area that manufactures like Icom, Yaesu, and Kenwood has not been able to match. Sure, there has been some feeble attempts to offer decent remote and control software for these radios, but they have typically fallen far short of Flex Radio offerings. However, owners of Macs have been left out of the fun for many many years. In the past Mac users were forced to use the workarounds such as virtual machine software like Parallels or Apple Bootcamp to run the Windows version of SmartSDR. This approach has worked pretty well in some cases, but in other cases it didn’t always achieve the best results depending on the machine configuration. Finally, we have a native SmartSDR client for Mac users which will allow SmartSDR to run more efficiently on …

Boxchip S700A Network Radio Review

More and more Amateur Radio operators are beginning to realize the flexibility and utility of Network Radio. Network Radio has become the “Swiss Army Knife” of communications technology. Amateur radio users can reach other Amateurs world wide using such applications as Zello, IRN, Echolink, and APRS. New applications are still popping up. For example the recently released Android app Peanut now allows users to use some popular D-Star reflectors using an android device. The user doesn’t even need a D-Star radio or a hotspot, just an internet connected Android device. In the past month this application has increased D-Star traffic on the popular reflectors dramatically. Not to mention that Zello can be used to establish a repeater like function for Amateurs who don’t have access to a local repeater. Zello can also be used to augment existing repeaters by increasing access to the repeater over unlimited distances very inexpensively. Also since there is no antenna required it allows Amateurs who are in antenna restricted to go back to rag chewing with other Amateurs across the world. Most users can give Network Radio a try by simply downloading the appropriate apps on their cellphones. However if you get hooked, you …

Kyocera E6560 – A Cheap Network Radio Rugged Smartphone

If you are interested in getting into Network Radio, but not ready to spend $150 to $300 for a dedicated HT style device, you might find that the Kyocera E6560 Smartphone might fit the bill. The Kyocera E6560 is basically a ruggedized unlocked GSM Android Smartphone with a PTT button for Zello use or other PTT applications that sells for $75 to $80. The E6560 has a great build quality and feels good in the hand. Unlike the typical Network Radio HTs the E6550 sports a 4.5 inch screen that makes operating the unit far easier than the 2.5 inch screen models. Not to mention that the E6560 is far more pocketable. The dual front firing speakers provides plenty of volume like the HT style devices for use in noisy environments. So, if you are looking for a dedicated inexpensive Network Radio Device rather than carrying your expensive smartphone around check out the video below from Ham Radio Science.

Pulsat PM-1100 Network Radio Review

Having found the X Boss TM-7S a great deal of fun, we took a look at a mobile / base version of a Network Radio the Pulsat PM-1100. The Pulsat Network Radio is pretty much identical to the very popular Inrico TM7. The Pulsat Network turned out to be very nice compact mobile / base unit for Network Radio use with a few quibbles.
