Welcome to CallSign Software. We produce custom integrated radio station software for the Amateur Radio Operator and Shortwave Listener. Our software offers features that are targeted at the radio and an Integrated Station Monitoring Facility. Each Package is customized for each radio. “It is not just one size fits all!”

We strive to perfect each software package. We test each package on EVERY radio that it runs on. We do not rely on our users for software testing of untried software on a radio we do not own. In fact we own EVERY radio we produce a software package for and DO NOT just throw in radios because they are similar. Each radio type is unique with its features and basic timing. We thoroughly shake down each pacakge BEFORE it is released. This software has been developed and continues to be developed by a long time HAM, WA1EYP, and Professional Software Engineer with a speciality in real-time 24x7 systems and 35+ years of experience in the industry. “We know how to develop high quality software and we will not charge you to fix our bugs!”. We have sold over 550 copies of our software in 25 countries world wide. We have a dedicated group of beta testors that usually find some obscure bugs. Each panel goes through a minimum of 30 days testing prior to release. We place “QUALITY BEFORE PROFIT”. So if you want high quality software and not pay Microsoft fees give use a try. We are not perfect but our developer, a HAM and SWL is responsive to user's needs.

We are SLOWLY expanding our base of supported radios into the ICOM, Kenwood, and Yaesu product lines in order to maintain our level of quality. If you do not see a supported radio that you are interested in then just ask Mike. It may be in the works. Each panel does take time as we are committed to maintaining its quality BEFORE and AFTER initial release with frequent “FREE” updates.

We include an array of features that make the software an integrated station position. In addition to radio control we offer the following Array of capabilities (Where applicable to each radio's capabilities). Here is a brief summary of the many features we offer the HAM and SWL operator:

We offer software for the Elecraft, ICOM and Ten Tec product line including the Ten Tec Pegasus, Rx320, Rx350, Jupiter, Elecraft K2, and ICOM IC-R75. We offer features designed by our HAM and SWL users that bring the true “spirit of radio” to your computer screen. We take advantage of Digital Signal Processing (DSP) and 32 bit programming in creating a set of radio control panels that employ powerful signal analysis tools with a flexible, user customizable interface, and an integrated station monitoring capability.

Our Amateur Radio and Short wave radio software is fully configurable to suit your operating habits and style with selectable meter types, tuning dial formats, knob types, filter access, and various (sound, sample, average, spectrum) scope displays to suit your operating style. The support of DSP technology and our own Custom Digital Filtering Techniques in our Spectrum Scope Displays allow users of all skill levels to locate signals under noisy band conditions.These filters reduces the unwelcome signal noise and interference on our spectral display scope using CallSign Software’s proprietary PC based Digital Filter and Noise Reduction Algorithms.

Using our Smart Mouse Control you can control your radio at the click or a roll of the wheel or search out additional stations using our interactive spectral scope feature with the ease of a point and click operation. Monitoring has just been made easier.

We feature an extensive database capability with indexed searches on any one of the 27 customizable database fields available to the shortwave listener or Amateur Radio Operator. Camp on that DX Cluster while simultaneously streaming filtered Cluster data to a text file or logging facility with our Ultra panel series. We have raised the bar on what whould be expected from a high-end integrated station control package.

We offer an extensive set of “control functions for the digital operator”. Our digital users have developed advanced digial mode controls in our transceiver panels for the Amatuer Radio Operator that are second to none.

Introducing the new series 4 “HamStationUltra and ScopeStationUltra”, a family of advanced Integrated Station control panels for the Amatuer Radio Operator and Short Wave Listener.

Our popular Shortwave Receiver control panels the “ScopeStation and ScopeStationUltra”, are an advanced spectral display scope, integrated database, with Station Monitoring. We feature Receiver control panels for the TenTec and ICOM. Our extensive Database Capabilities were designed with the SWL in mind. These panels were built specifically to optimize the monitoring capability of these radios.

Now Available: ScopeStationUltra: ICOM IC-R75; TenTec Rx320, and Rx350
HamStationUltra: TenTec Pegasus and Jupiter, and Elecraft K2.

Coming Soon: Yeasu FT-2000 HamStationUltra: Advanced Station Manager. It has ALL of the frills of our HamStationUltra and mates with your FT-2000 station. The delevopment of the Advanced Station Manager Software is completeing. Check out a current view of our pre-release front panel of the Advanced Station Manager on our New Products page... and the best part is that you will not have to take out a loan at the bank to get one!
