Boxchip S700A Network Radio Review

Introduction
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.

Network Radio – Is it real Ham Radio?

Introduction
Network Radio began gaining some interest as an amateur radio format about a year ago. During the past year Network Radio has gained popularity with Amateur Radio operator as well as with radio hobbyist in general. The most popular aspect of Network Radio has been based around Zello using their mobile phone apps for IOS and Android. Basically Zello is an VOIP service with a push to talk feature that can be used over WiFi or cellular Data. There are two versions available the free personal version and a paid commercial version that offers a larger feature set that would be of interest to business users. Zello allows for the creation of groups. These groups can range from just a friends to thousands of members in a group. When a user presses the push to talk button on their phone’s screen, the voice message will be heard by all users in the group in pretty much real time. Zello claims to have a worldwide user base of 120 million users at the time of this writing.

How does Zello Work?

Since most people use the personal version of Zello, simply download the free app that matches your devices operation …

SDRplay RSPduo End User Review

Introduction
After using the new RSPduo for a couple of months, I can say yet again that SDRPlay has produced another excellent product in their inexpensive line of wide range SDR products. After the original SDRplay RSP1 was introduced SRplay continued to enhance and improve the platform by releasing new models with improved and new features. However the new SDRPlay RSP units such as the RSP2, RSP2pro, and RSP1A were evolutionary products. Recently SDRplay introduced a revolutionary SDR product with the release of the RSPduo. What makes the RSPduo unique is that unlike previous RSPs, the RSPduo use two separate 1kHZ and 2GHz 14 bit tuners each having up to 10MHz of bandwidth. Of course the best part is that SDRPlay managed to bring the RSPduo to market with a list price of only $279 is pretty amazing. Ok. lets put that into perspective. Right now their only two SDR transceivers  on the market that feature dual independent receivers. They are the Icom  IC 7610 (street $3200),  Anan 7000DLE ($2995),  Anan 8000DLE ($3595) and the Flex 6600 (starting at $3999). Ok to be fair, these radios are 100 to 200W amateur radio transceivers, but if you want a SDR receiver …
