And of course we maintain a close cooperation with Red Pitaya, who at our suggestion upgraded the original STEMlab 14 equipped with 14Bit A/D converters to 16 bit and improved it for SDR applications.
We are continuously working on further development of the device and improvements, incorporating the experience of many OM's. Our HW and SW can be found in the meantime on the Neumayer Station in Antarctica as well as with radio amateurs in Europe and the USA.
In the present configuration the unit has the following components with the corresponding technical features: - Front panel, Midi compatible with 7" display 1280x800 resolution. - 16Bit STEMlab - 1x Preselector 11Band plus 1x Path Through (RX1 and RX2) - Windows 11 PC Intel Core I5 or I7 with 16GB or 32GB Memory and 1TB SSD - VFO knob in brass
One disadvantage of the Hilberling PA is that the input power cannot be adjusted (default 75W). This means that with the Charly 25 transceiver with an output power of 20 watt, I can only achieve 500 watt with the Hilberling PA HPA-8000B-54.
