Apache Labs Looking Good   August 22nd, 2013

ANAN-10F

What do you Think of It So Far?

I have been running the Apache Labs SDR radio for a few days now using OpenHPSDR which is the recommended current software. The PC is coupled to the radio via ethernet. This makes a very simple, stable and versatile arrangement.

The installation was simplicity itself and went without a hitch. There is a bit of waiting whilst the installer writes files and this took quite a few minutes on my PC which is dual core 2.4GHz with 6GB of RAM. After a few opening entries to make, guided by questions, I was ready to go. It all fired up first time and has proved to be very stable.

The receive side is superb with excellent sensitivity and quite amazing IF filters. The dynamic range is claimed to be around 125dB. I have no way at home of measuring this, but from reports from other users, few are arguing with this figure.

In all the SDR software that I have used, tuning has been achieved by grabbing the screen and dragging it past a stationary cursor which represents the IF passband. This software operates in the same way, but has a feature that I have never seen before but which is extremely useful. You can lock this traveling screen and instead move the central “pointer” around as in a more conventional way. This is an excellent idea for keeping track of signals in certain positions across the dial. It means that everything stays in the same place when you’re tuning.

And the other good thing is that there does not seem to be any issues with CW. Many SDR users have struggled with CW because the software could not cope with fast CW. I tried sending at 30wpm and found no issues. Looking on the internet I could see no mention of CW problems.

I have enjoyed my first few days with this radio and have operated both the low power ANAN-10 model and the 100W version. Apart form the power levels, they both seemed to achieve similar performance. It all looks very good and I will report more about them at a later date.If you want to see them working in a live situation, we hope to have a couple of stations working at Newark at the end of September.
