Lsb &usb low on freq

I hope you have the right equipment to work on this. http://www.cbtricks.com/radios/galaxy/dx99v/
If it was modded you may be in for a long haul. There are a lot of youtube vids on how to mod radios and not many of them do it correctly. Good luck

if it transmits on AM and LSB then it should transmit on USB . You will need two devices, a spectrum analyzer and an oscilloscope. If you don't have them then take it to a tech to get it fixed.

something to do with the SSB filtering maybe, sorry i cant be too helpful!

If it doesn't say call the mafactor

An external freq counter will always do a better test then the one on the unit . Do you have an oscilloscope? A function generator will also have a freq counter . Now the ultimate is a spectrum analyzer. you don't need all these but the function generator will work fine.

• Well, AM is Amplitude Modulation and Sideband suppresses the carrier and uses only the top half (upper sideband) or lower half (lower sideband) of the wave.

• Whether using AM, USB or LSB you are on the same frequency although if someone is on USB and you are on LSB you will not be able to understand what the other person is saying because you are using different parts of the wave. So 27.185 (channel 19) on AM, USB or LSB is still 27.185.

• If you have further questions please let me know.

• If you have any comments please feel free to leave them here.
• Hope this helps and thank you for using FixYa.

FM - Freq. Modulation

AM - Audio Modulation

USB - Upper Side Band

LSB- Lower Side Band

CW- Morris Code

most likely been fiddled with and out of alignment. If you have a freq counter and a volt meter you could possibly fix it yourself. look at cbtricks.com for the aligment procedure.

U mean on sideband? Frequency counter only useful on other than sideband operation. This does not mean the carrier insertion osc. is on frequency. If it needs adjustment, your voice will sound high/ low on transmit. Incoming signals will sound right after adjusting the osc.

ghilger, First off, has your radio been converted to open up all the other channels(including CB)?? That has to be done first, or it's locked in the ham freq's. I think the factory manual is pretty well detailed, but i've been around radios my whole life. The mode button does the changing from am/fm/usb/lsb.Here's from the manual;

MODE: Operating Mode. Press the MODE control to select the operating mode. The operating mode is indicated on the liquid crystal display: am, fm, usb, or lsb.
* See, there is 2 different functions for each button. One set of functions are by just pushing the buttons, the other set of functions are obtained by pushing the function button first. The function button is activated by pushing in on the clarifier knob.
*Here is for saving of freq's;

Memory Save. To save in memory a specific
frequency and operating mode, select the desired mode and rotate the FREQUENCY control to the desired frequency. Press the FUNC button, and then press the M.SAVE button. S will appear on the LCD next to the frequency. While S is displayed, immediately press any of the memory channel buttons (1 - 5). The mode and frequency is now saved into memory. If the S indicator disappears before you press the memory channel button,
the information will not be saved and the process
must be repeated.

M.LOAD: Memory(Recall). To recall, any of the saved memory channels press the M.LOAD
button. L will appear on the LCD for several seconds. While the letter is displayed press the desired memory channel button (1 - 5). The programmed mode and frequency will be displayed.,
If you have any more questions about the radio, repost them here and I'll try to walk you thru them. The radio is a very good ssb rig, especially set up with a power mic. Hope this helps,, Mechanic
