![]() ![]() I happily ran mine from 2010 to 2014 and never thought about moving to anything else until the direct sampling rigs began to show up. Yeah, the Flex 5000 was (still is) an excellent radio. My flex 5000 was a nice box, I had no real issues with it (for a 25 watt radio).ĬPU was under 10% at the time and I could get the latency very low with the firewire. I did not know you could get the ANAN without doing the customs nonsense. when making your decision, think about whether or not it's really an advantage to lock your future feature-set to the internal FPGA. My "thick client" OpenHPSDR software typically runs at between 4% to 7% cpu utilization on a 4 year-old I-7 computer I built myself, which is far different from my Flex 5000 running PowerSDR which used to sit at around 45% cpu utilization on the same computer. Since all the processing is distributed across your LAN the latency is typically less than 1 ms. Additionally, it allows the programmers to seamlessly allow full spectrum FFT data crunching to your computer's graphic card (NVIDIA gpu) or even a cheap single board computer plugged into your home LAN's router (NVIDIA Jetson T1 board less than 200 bucks) using ARM processors and CUDA cores to handle all the heavy lifting. ![]() This opens the door for the firmware and software programmers to distribute the tasks over the low-latency ethernet connection between the radio hardware and the computer. With the thick-client ANAN approach the processing tasks are distributed (balanced) between the onboard FPGA and the computer. The trade-off is that performance and future-proofing is locked to that FPGA in your hardware. With the thin-client Flex you are relying on the onboard FPGA to handle most of the DSP and other processing tasks which certainly does lighten the load on the computer. There are two schools of thought regarding the thin client (Flex) and the thick client (ANAN) approach to the SDR platform. I'd suggest also taking a look at the Apache Labs ANAN-100 as well (also interfaces to the computer with ethernet) which is selling for $2449 with free shipping from Ham Radio Outlet. These features make it a versatile tool for amateur radio operators and SDR enthusiasts who wish to enhance the functionality of their IC-7300 transceiver.The Flex 6300 is a nice hardware platform for a nice sounding SDR for AM and at $2499 it will run circles around box-type radios at the same price point. Its high input impedance design allows for distortion-free tapping, and its wide frequency response provides versatility in monitoring various frequency ranges. By avoiding loading, the PTRX-7300 ensures that the measurement does not introduce unwanted attenuation or distortion to the signals passing through the transceiver.Ĭompared to more traditional methods of using a panadapter with a transceiver, the PTRX-7300 offers several advantages. This amplifier serves to monitor the TX/RX line of the IC-7300 without loading it. This broad frequency coverage enables users to monitor a wide range of signals and frequencies using their IC-7300 transceiver.Īnother important aspect of the PTRX-7300 is its built-in high input impedance amplifier. One of the notable features of the PTRX-7300 is its flat frequency response, which covers a wide range from 30kHz to 120MHz. ![]() It functions as a wide-band panadapter by tapping into the transceiver's TX/RX line and allowing it to be used with software-defined radio (SDR) applications. The PTRX-7300 is a novel accessory designed specifically for the ICOM IC-7300 transceiver. ![]()
