Used it for a few weeks and now the tuning on AM and shortwave has gone completely flaky. When slowly tuning up on the SW2 band, it will jump right over from 11000kHz to the 13000's and will sometimes just waver around no matter how gently I turned either tuning knob.

Here is a link to the manual for your radio.
http://www.etoncorp.com/sites/default/files/GS750_Manual.pdf

There are few reasons why blade jumps off, you may have a poor weld on the blade. Tension could be too tight or too loose. Make sure that the blade tracks properly. I advise you to watch videos about tuning up a band saw or check some informative blogs on bandsawblog.com. I purchased my blades on sawblade.com , check them out if you need any.

The buttons are marked and the use of most of them is self-evident.
The number keys are used to enter frequencies (direct tuning).
Lock locks the radio and prevent changes (trurning ON or OFF, changing frequency, any function change is blocked)
Sleep sets a timer.
+, - go up or down in frequency, or when you are setting time.
U/LSB is for toggling Upper or Lower Side Bands.
Auto Up and Auto Down are for the automatic tuning system (scanning the frequency spectrum)
AM is for switching to the AM (medium wave band)
AM/Meter band is for switching to the Short wave bands, and FM is for Frequency modulation band.
VOL + and - increase and decrease volume levels

Page/time: It has 700 memory locations to store frequencies. These are organized in pages (maybe up to 100 pages). You jump to next page with that button. Used also when setting time . Please read the instructions.

F1 to F7 are used to select the day for the alarm. F1 for Day 1, Sunday, F2 for Monday, etc) You can set an alarm for each day of the week.
Reset to reset configuration
TZ/Line in TZ set time zone, Line In if you wan to use the speaker of the radio as the output device for a signal from some other radio, or MP3 player
The tuning knob may also be used to change the displayed value while setting time (I can't remember exactly. You have the manual)
Erase erasing a stored frequency or a page (Check that)
Copy see above.

Hi,
If you are experiencing bad or NONE AM (MW) reception ,if your receiver has an external antenna connection point here is the solution... It should also have a ground connection as it is rare such a point does not accompany an external antenna connection.
The problem with MW reception is the vast frequency range of the MW band as" 540-1760kHz "
means nighttime fade out, and even heavy static and distortion..( less than SW )
in order to receive a station on LW and MW bands you need to have a "Loop Antenna " that normally supplied by manufacturer..if you cant locate it ,you can buy it in any electronic store..it is a very cheap accessory..additionally both LW and MW works good in daytime with powerful radio stations in your vicinity ..espacially LW..not much stations on these days..except in Europa..MW works better and more stations come after sunset ..
SW band is a little bit different.if you really want to listen SW in depth ,and if your receiver has multiple SW bands as well ,you then need special SW antenna to be attached to your receiver..otherwise it is not worth to listen it due to heavy static and distortion on the band..,unless you want it..just for testing and to see what is available in your area pls attack a plain wire (about 1 meter ) to ext antenna plug and try to search it..if you desire to learn shortwave -Listen To The World please visit the URL below.

On the Satellit 750 you have a button marked SSB. If you have selected a shortwave band then you can press the SSB button. Pressing the button repeatedly will toggle between LSB and USB.

You will need to know the exact frequency and the broadcast time, and the side band. Turn the radio on. Select a frequency which you know carries SSB signal and wait. Those that broadcast on SSB are not radio stations, maybe ham radio operators.

You can also select a short wave band, press the SSB button once or twice to select the side band and launch the automatic tuning system. It will scan the meter band and stop for a few second when it receives a strong enough signal. If you are able to perceive a clear signal on LSB or USB then you found a broadcaster. Some radios just have SSB and you cannot choose the side.
Personally, when I buy a radio I always insist on SSB but I have never been lucky tuning in an SSB signal. I keep trying once in while.

It sounds like the whole am band is not working which includes the shortwave bands, there is no remedy to correct this and is clearly a manufacture defect. The best solution is return the radio because there is nothing more that can be done in it's present condition.

The most common problem for no FM is the failure of component F1 IF transformer. One of the windings on the transformer opens, so you have either no input, or a very low level input to the FM mixer. You need to obtain a copy of the Satellit 700 service manual, and then find F1 in the schematics. You can check the windings with a simple ohm meter to verify if one of the windings is open or not.
If F1 is defective, and I have seen many 700's with this fault, you need to replace it with an adjustable 10.7 MHz IF Transformer in a 7mm can configuration.
I found a replacement 7 mm 10.7 MHz IF Transformer at Talon Electronics. Their part number for it is IND2134, and it costs a whopping $0.80. Here is a link:

Usually the "front end" of the radio has a bad FET transistor. This is caused by a static zap at the antenna. Early models suffered from this and the cure is to replace the FET and add protection diodes. If you need help with this email me at.... [email protected]

Before you call a doctor or an exorcist, verify that you're using your shortwave receiver under normal condition. There are several factors which affects reception of whortwave programs and signals.

1. Check for the time and frequencies. Depending on your country and location, all Shortwave time zones are based on World Time in UTC or GMT ("Universal Time Coordinates" or Greenwich Mean Time") In my country (Philippines, Asia) for example, we are 8 hours advanced from World Time. You can check your time zones and regions using a world map.

2. Check for propagation and band conditions/ openings. During daytime higher frequencies such as 9 -21 Mhz are active, while nightime frequencies are the lower bands such as 3 - 9 Mhz. Daytime and nigthime divider frequency is about 10 Mhz, that means you might receive signals under most conditions during daytime and night time. Check some technical books on amateur radio operations or magazines for radio reception. It might be worthwile to study books or materials on receiving international broadcasts stations before you can receive good or adequate shortwave signals. This might become your hobby too, "DXing" or receiving distant stations from across the world. Try it, but it might be an addicting hobby once you're drawn to it!

3. Check if any shortwave station broadcast in any specific time of day at any frequency. Shortwave broadcasts are scheduled based on band openings mentioned above. If for example I'm a Shortwave broadcaster from Asia, and would like to broadcast my signal through the Americas, I would use band openings with respect with time zones. If it is night time in the Philippines, and daytime in the Canada, I would use the higher frequencies to propagate my signal. So I would specify the time for example "8:00 pm Philippine local time, 12 hours UTC, and 7 am in Canada"--- Asia: 8 hours advanced to UTC, Canada--- 5 hours behind to UTC). So shortwave broadcast schedules varies. Broadcast schedules are available on the net, just search for the Shortwave station you want to hear such as Radio, Japan, Radio Australia, BBC, DW (Deutche Welle) Radio in Germany, China Radio International... There's too many shortwave stations waiting to be discovered out there! Check some books and magazines too such as Popular Communications, Monitoring Times, Passport to World Band Radios, World Radio and TV Handbook, etc. You may want to check if any station would be broadcasting in your dialects as most of these mainstream and regular broadcasters are multilingual.

2. Check your location. If you are using your radio indoors, shortwave signals might not entering your homes or offices due concrete walls and metal railings or fence. There are many factors which blocks radio waves especially in the HF or lowetr bands. Try receiving AM (Mediumwave) first. If it cannot receive any AM station, then you would not receive any Shortwave signal at all, even if you extend fully the telescopic whip. If you cannot receive AM or Shortwave signal indoors, try using your receiver outdoors.

2. Check for local interference. Your receiver might be receiving interference from noise generating gadgets such as PC monitors, TV sets, faulty wall adapters or switching power supplies, motor operated appliances such as washing machines or vacuum cleaners, flourescent lamps, etc. Try turning off or unplugging each of these mentioned gadgets to see if they are the cause. Faulty house wiring or powerline noise might also cause some interference noise which could drown shortwave signals, verify this with your local electrical technicians.

3. Check your radio's settings. Depending on the radio that you use, there might be settings such as attenuator or RF gain, be sure that attenuator are set to zero or turned to off, and RF gain to high. Attenuator must be turned to minimum or OFF position, unless you are receiving too much signas from nearby radio stations. Setting attenuator to mid or high position will attenuate most weak signal, and only those strong local stations will pass through. Setting too much attenuation will prevent you from receiving any station at all. Same with RF Gain, always set it to highest gain setting unless you are receiving too much signals which might overloads your shortwave radio.

4. If these troubleshooting efforts above doesn't works and you still cannot receive any station, then your radio's front end parts might had burn out due to signal overloads. Burn parts might include one or several transistors or diodes. Let your local service technicians check your radio and solve the problem for you. If your radio is still under warranty, send it back to the store or dealer, and let a qualified technician do the repair.
