The Hagenuk RX 1001 M is a receiver which was built for military- and marine communication. It is most certainly still in operation on some ocean vessels and probably in some coast guard stations. Typical as other professional receivers is the RX 1001 M built very solid. In comparison with hobby receivers does it look like a tank, certainly from the point of weight and size. The receiver only weights almost 17 kg and with the housing it puts almost 30 kg on the scale. This is understandable because it is built for daily operation under professional conditions for many years. My RX 1001 M was a so-called “depot receiver”, a backup receiver and was never taken in operation. It looks as new even when it was built in 1992. The Hagenuk RX 1001 M has a tunable frequency range from 10 kHz – 30 Mhz for the operating modes AM, USB, LSB, CW and RTTY. Tuning steps are 10 Hz and 100 Hz. It has 99 memory channels which can be scanned with various search modes. Each channel can be individually programmed, for example “Scan by Time”. This means that each memory channel can be activated for a defined time period starting from a set time. This is a great feature for unmanned frequency surveillance stations. The receiver has a very good large-signal behavior of IP3 +26dbm, although only from 1 Mhz upwards. The Hagenuk is easy to operate. It is not as with other receivers which have for each function a button. No, a code has to be entered via the keypad when for example the mode has to be changed. When AM mode is required has the code “11” to be entered. For LSB has the code “13” to be entered, each function has a code. These codes are clearly marked on the front side of the RX 1001 M. The active function is marked with a LED. The massive main tuning knob is first class, which is magnetisch rasted. Just beautiful to turn the main tuning knob. This is also the case for the BFO knob. The receiver has a build-in loudspeaker which does not sound that bad and can be switched off by a switch on the front panel. All other functions and switches are self-explaining on the front panel.
How about the reception !
First its strengths: very good reception in SSB, very good large-signal behavior and a very good sound. From about 500 kHz upwards is the RX 1001 M very good. Below can, certainly in the evening hours, large-signal noises be heard. Apparently is no low- pass filter installed for operation below 1 Mhz. Only when the optional pre-selector is installed, is a low-pass filter installed. This pre-selector is hard to get ! As previously mentioned is SSB its real strength. The reception is almost noise-free and very understandable. For DXing in SSB mode is this definitely a top-notch receiver. With a good audio filter, such as example the Dierking ED 88 NF, can disturbing noises be cut out because the receiver has no notch-filter and band-pass tuning. In AM mode is the sound also very well but a light clear noise can be heard which is disturbing with weak signals. But there for helps the SSB mode or an audio filter.
Final statement : a top receiver especially in SSB, just pure fun !
Why a professional receiver ?
It is not just the reception quality that makes such a receiver interesting. A Drake R8B, which I also have, or a JRC NRD 525G, are definitely not that much inferior to a professional receiver. Yes, even in certain situations has a professional receiver to underdo.
It is more the fascination having a professional receiver in his shack. Just its size and weight are crazy. The original packaging is so stable that it can withstand an earthquake. The manuals with all its schematics and service manuals are a 10 cm thick binder. On top of that is an extra binder just for spare parts. Of course is also a quality certificate of the quality control included.
It is just pure fun listening to the shortwaves with such a receiver.
