The VR-5000 is a relatively compact desktop receiver and therefore also suitable for mobile / vehicle use. Essentially, the apparatus is aimed at listeners who wish to cover over a wide range of frequencies but which do not require articulated control functions on the signal. The front panel over the tuning control has in fact adjustments via knobs only for volume, tone and squelch. The remainder of the interface rests on a set of buttons not too dissimilar to those commonly found in a portable scanner. It operates in dualwatch, that is, integrates two independent receivers that can be made active at the same time.
Other features: panoramic real-time spectrum analyzer, selection of different bandwidths on IF filter for AM mode, DNR / notch / digital audio filter (with optional DSP-1 unit), noise-blank, VCS function to unlock scanning in the presence of an unmodulated RF carrier, input attenuator, RF-tune function for input filters, squelch, digital audio recorder (with optional DVS-4 unit). Multiple search options: between band limits, within the memories, on a priority channel, with auto-storing. Wide range of general memories, 5 priority channels, customizable locations with alphanumeric characters. Clock with local time representation or UTC. Large multi-function display. CAT connection for the memory contents cloning and PC control.
Performance and practical notes :
It is stressed that the apparatus has undergone changes over time in both the electronics and the firmware, the initial versions have indeed highlighted drawbacks and then requiring improvements. This justifies, but only partially, the discordant opinions that accompanying the VR-5000 being some negative tips related more to a single version than to the definitive production of the receiver. On the other hand there are also two concrete reasons that make it difficult to express a judgment on the behavior of this model. A first point is identified in the union between susceptibility to intermodulations and spurious responses, in other words the RF dynamics and the effectiveness of the filters in the front-end. These factors are very variable depending on the frequency and therefore lead to different qualification of the apparatus that in fact has a non-homogeneous yield between HF, VHF and UHF. A second aspect emphasizes a lack of the producer who does not univocally declare the selectivity values for the various modes. Overall, the price / performance ratio is not excellent and while the wide frequency range satisfies the operators looking for a multimode scanner, those who practice a demanding radio-listening find limits of use.
Your review :
In the HF frequencies, as reference I bring the 7 MHz inherent to the important 40 meter radioamateur band, operating in the LSB or USB mode sometimes it is difficult to clearly understand the speech even if sometimes it is perfect - for me it depends also on who transmits but it is not the only factor, however. Always remaining to this type of listening there is a non-optimal selectivity that leads to hearing fragments of strong modulations coming from the near frequencies. The sensitivity to the truth is good, working weak stations is not a problem.
