Hi Joe, When I bought the Roberts I did check it had SSB and you can switch it too USB or LSB instead of AM - is that what you meant? Anyway I had quite an exciting reception the other day because I was scanning around 41m on LSB and found some local radio hams having a good chitty-chat. I know they were local because they mentionned some places around town where people in their group came from. One day I wanna get a transmitter too... :-) Also since I last posted I have received Iran (Voice of the Islamic Republic of Iran), Vietnam, China (China radio international), Albania, the U.S , Voice of Russia (World service), Brussels. I'm going to send off for my first QSL card from Brussels (Radio Vlaanderen Internationaal - www.rvi.be). I still haven't heard anything of V.O.K and I've tried every different frequency I have and at different times. I think there is a lot of interference around here (it sounds like electrical noise). I tried turning off everything I have electrical in my flat (and also the fluorescent light in the hall outside my apartment) but to no avail it doesn't seem the noise is coming from here. My friend told me to try connecting an aerial we already have on the roof to the radio which I wouldn't have tried usually because it is a satellite dish (and I thought they were for receiving microwaves) but anyway we tried taking the thick middle cable of the lead (the aerial rather than the earth shielding around it) and wrapping it around the FM aerial of the radio. That seemed to increase the signal coming in which is odd but it also gives something if I put it into the TV so I gather sometimes the wrong aerial type can be bette than none at all. Anyhow I suppose it would be even better to make up a jack and plugh it into the AM aerial socket but rather than waste time messing around with that I think building a real aerial is my next move. The way I understand it I need to get a length of normal insulated wire, single core (does the gauge matter or will any do?) lay it on the roof in more or less a straight line (I am thinking to put weights at certain intervals to stop it blowing around) then connect that to some radio co-ax at one end and trail that down the side of the house and into the window to plug in the radio? The questions I have is (i) where should I plug the earth of the radio co-ax? (the outer layer shielding thingie) (ii) are these "ceramic stand-off insulators" capacitors or what ? if they are what values should I use ? I can understand the risks during a storm but people never unplug a TV aerial when they finished using it - why is that? Is it because there is some protection or is it because the risk is very low? I will take a look at prime-time shortwave when I get time. Can you recommend me any good URLs for reading and learning about things? A lot of it seems to assume you already know all the basic stuff which I don't (I know more than average but I'm regularly left misty-eyed reading radio-ham pages after a couple of KOVAs, QOLs and DXes ;-) bestwishesfrom laura Dear Ms. Laura, Contrary to a post above, the Roberts R861 is equivalent to the Sangean ATS 909, a radio which is superior to the '505. It is a good (not great) short wave portable radio. However, it does not feaure the synchronous selectable sideband circuitry which the Sony features and which, in my opinion, makes all the difference in pleasant listening. I habe never owned a Sangean ATS 909 nor do I know anyone who does. According to PASSPORT TO WORLD BAND RADIO, the Sangean/Roberts works BEST off its AC adapter as it "eats" batteries. An external antenna is necessary also, as it lacks sensitivity with its whip (according to them). A long wire, or loop antenna, mounted on your roof would be ideal. Try buying a length of insulated wire, two ceramic or equivalent stand-off insulators (to isolate the antenna from whatever support you use) and some lead-in wire; attach the appropriate plug to the lead-in to attach to the radio and you're in business. No separate ground is necessary, but make sure you DISCONNECT the antenna whenever the radio is not in use and, especially, during local thunderstorms. (NEVER use ANY electronic appliance during a thunderstorm; storms only last a half-hour or so.) Do NOT let your antenna proper or the lead-in touch anything metallic; that will degrade the signal. Tall buildings don't impact short wave signals; electrical "noise" from computers, fluorescent lights, light dimmers, and other such modern accoutrements do, however, and it is best to turn these off if possible. Especially turn off such items one by one to see if the particular item is causing interference. (Of course, you can do nothing about your neighbors.) I have a very bad situation at my location with local electrical noise and I have been able to find a solution, but it would not be appropriate for you as it cost a great deal of money. I received VOK several weeks ago at about 0130 on 15180 kHz (actually a "hair" off that frequency). I haven't heard it since, but, frankly, have not tried either. Perhaps in the next couple of days I'll listen for it again. Do you know about Prime Time Shortwave? Just enter that in Google and it will take you to one of the best short wave schedule programs on the web (it's free!). There you can find the latest information on any station you might desire - its time and frequency and the "target area" to which it is transmitting. This often lets you have a "fighting chance" of picking up the signal. All the best, and the best of luck with your new radio, Joe laura fairhead wrote: fOn 10 Dec 2004 06:40:32 -0800, "Joe Analssandrini" wrote: Hi Joe, I was an impatient child in the end and went and bought a Roberts R861. They actually retail for quite a bit more than the Sony but I'm not sure I did the right thing :O Its difficult for me because I can't get deliveries where I live so I checked the local stores and to my surprise the local electronics shop he had a Roberts R861 (2nd hand but VGC) and was only asking =A3120 for everything including mains adapter. I'm happy because the Sony was going to cost more than that and the Xmas squeeze is on - I think I'm going to get so much into this I will end up getting the Sony soon AS WELL anyway ![]() realised is reception is rubbish here (right next door to a huge apartment block and lots of buildings on all sides we think are blocking the signals) The funny thing is that having the mains adapter plugged in seesm to improve the signal rather than degrade it (maybe it uses it as an aerial?) I understand that the telescopic aerial is for FM ? I plugged in the 'whip' (long wire thing) and put it as high as I could (not very much!) but we think it will be much better if we put an aerial up on the roof. Should I just put a long length of wire up there ? Is it alright to just dangle that down the side of the house to connect it or do we need to use a special shielded cable to do that? I want to have the computer running at the same time and it seems to interfer, maybe it would interfer with the aerial lead coming in ? (I don't know being inexperienced but that is what my hunch is...) Anyway I have been glued to the thing all night and wonder if I'll ever get to bed :-)) My first exciting discovery (I have been scanning and writing down the channels or a description) was "All Indian Radio" on 7.409Mhz. Also I think I got something from Nigeria on 7.382Mhz. I couldn't get Voice of Korea at all, not one iota. Do you think the Sony would fend better at that? Or is it just my aerial I need to set-up? What frequency did you get VOK on? Thanxs again, your post was very informative ![]() bestwishes laura -- echo |sed 's/\(.\)\(.\)/\2\1/g' |
