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.

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 …

SDRplay RSP1A First Look

Inroduction
SDRplay’s RSP1 has long been a great value in an entry level SDR platform for radio hobbyist looking to get involved in Software Defined Radio. The RSP1 has also been a favorite for adding spectrum displays to non-SDR radios or experimenting with SDR applications. The other advantage of the SDRPlay series is strong software support. SDRplay offers their own SDR program SDRUno which is a highly powerful and well polished SDR client that leverages all the features and capabilities of the SDRplay series. The SDRplay SDRs are also compatible with several popular 3rd party SSDR programs such as HDSDR, SDR-Console, and CubicSDR. Several PC platforms are also supported including Windows, Linux, Mac, Android and Raspberry Pi 3. SDRplay offers excellent support via their website and Facebook Page. In short, the SDRplay series offer a great value for an entry level SDR. The nice thing about SDRplay is the Jon Hudson and SDRplay Team are always looking for ways to improve the SDRplay platform, either through improvements in software or hardware. The SDRUno software is updated on a regular basis with new features and improvements. The RSP2 was added last year and offered hardware improvements and new features. Frankly, …

SDRPlay RSP2 Review

Introduction

If you have read our past articles on the SDRPlay RSP, you probably noticed that it has been a highly regarded SDR receiver here at HRS. It was named as the best SDR radio available in its price category. The SDRPlay RSP is even good enough to hold its own against far more expensive SDR products. Not to mention that it comes with excellent support from SDRPlay team. Over the past year, the SDRPlay got even better when SDRPlay acquired the excellent Studio One SDR software and adapted for use with the SDRPlay RSP. The new version of Studio One for the SDRPlay was renamed to SDRuno. The addition of SDRuno to the SDRPlay makes the RSP even a better value by adding a very powerful SDR program with a very attractive and professional user interface. Unlike some SDR programs that look pretty dated in comparison. The SDRPlay team continues to add new features and improvements to SDRuno on a very frequent basis. Not to mention that the price of the SDRPlay RSP has been lowered to $129 and is easily available in the US from Ham Radio Outlet. With the SDRPlay RSP’s low price, continous coverage from …
