Short wave SDRadio
The rig is a very nice package out of the box. Giving a number of cornerstone feature to a attractive pricing:
- All band shortwave radio
- 20watts output
- Built in autimatic antenna tuners
- SSB, CW, AM
- separate analogue in and output for digimodes from mini-DIN connector
- SDR ( Software Defined Radio ) architecture
- Small size and resonable weight – 40 x 120 x 180 mm, 1.5 kg
- Hand mike with button control
- Impressive little 1.5 inch OLED display.
- Detachable front panel – To be put remotely from radio unit.
After having had the radio for a couple of weeks time now I must say that Im pretty impressed with its performance. I like SDRadios and have a couple of them. The spectrum display/waterfall is a must when running a short wave radio, hunting for activity, unused space and evaluating stations on air.
The software in a SDR is a cornerstone for good performance. And of course here the G90 is doing a great job.
But no construction is perfect, and the G90 is no exception. Most stuff is ok, but I would limit this to about 75% of what I would like to see. A list of oddities have been sent to the factory / R&D to get fixed. I have installed FW 1.4 into my radio. Som updates are made.
Lets give you some examples:
- The Noise Blanker (NB) does have no real effect on the noise / interference. Also there is no way to set the level of the NB
- The compressor does not seem to do any difference to your output/sound. Also one can normally set levels in compression
- The display of the passband presents the passband for LSB and not USB. allthough selecting USB. Looks odd.
- In a SDRadio one can do pass band tuning (PBT) – I can see no function to this.
- There must be a more user friendly way of handling step rate on the VFO. Very often a step rate of 500Hz is needed. I would like to see a meny item where one could select the basic step rate per mode. From 10Hz to lets say 5kHz
- To activate the subfunctions of the buttons below the screen on has to hit the “FUNC”-button. It would be much better to activate the subfunctions by a “long push” of the button.
- The OLED display is great, and you can dim it with a quick push to the power button. It would be great to have it dimmed automatically after a variable time of inactivity.
- The text on the small push buttons is very hard to read in dim light. A portable radio like this often is used in them situations. I would expect that one can get them buttons back-lit.
- The menu structure is far from ready. Very hard to get around and one has a feeling that there are tons of functions that could be implemented.
The manual is a small leaflet of 38 pages. The English is ok but the content is less then adequate. And of top of that one can read in a couple of places about functions that yet are to be implemented. Like VOX….. Not even that is available in a radio when the calendar says 2019.
Modification and test articles
I have a upcoming test article to be published in the Swedish National ham radio magazine QTC. The reading is in Swedish ( Have fun).
I love the radio som much so i have bought it. You get a lot of radio for your money (About EUR 500.-) . Get yours from PilupDX.
Below i will publish some modification that I have doen to my radio. Though it would be of interest for you:
