Can anyone help me out with recommendations for a good receiver for
mediumwave DX ? I've narrowed it down a bit, but would like some more advice with regards to their operation with 240 volt mains and 9 kHz channel spacing. I presently have a Yaesu FRG-8800, which unfortunately has built in attenuation when tuning below 1600 kHz making it impractical for dx use on mediumwave. It is excellent for shortwave operation and also dxing our "narrowcasters" operating from 1611 - 1701 kHz, but a bit deaf below 1600 kHz. (There is an article online detailing removal of the attenuators, but it recommends against it if strong transmitters are nearby - I am 10km from an ABC site transmitting 50 kw on 612, 25 kw on 792 and 10 kw on 936, with little other than salt water & mangrove swamp in between). The radios presently under consideration are : 1) GE Superadio 2 I am presently leaning towards a secondhand GE superradio (analog tuning and they were available locally (from Dick Smith electronics) modified to operate on 240v. My concern here is that these radios will be getting on a bit - are there any long-term problems from the modification to 240 volts, and was the power supply filtering upgraded to cope adequatly with 100 Hz ripple compared to the original 120 Hz ripple ? The other problem is that they are rare as. 2) C Crane Radio Plus This would be nice, however it appears to be designed to work only with North American 10 kHz channel spacings, and 110 volt mains. Is it possible to modify the C Crane Radio Plus to operate with the 9 kHz channel spacing and 240 volt mains ? 3) GE Superadio 3 Would have to be ordered from overseas (not a problem). With analog tuning the channel spacing shouldn't be a problem, however will they run, or can they be modified to run on 240 volts ? 4) Sangean/Digitor "Outback 2" As a radio of "last resort". Advertised as having "long distance reception", however it seems as if the audio performance is probably down on the other choices, I also believe that the MW performance may be somewhat lacking but I have no way to do a side by side comparison. The big advantage here is that these are available new in stores right now. So, is it possible for either of the "imports" to run properly here ? Are there any other options I should be considering ? or should I just buy the outback 2 ? Any other ideas ? |
