DX959 - using the onboard frequency counter for alignment?
Posted: Tuesday 11th Nov 2008, 22:28
I have a Galaxy 959 which has an onboard frequency counter that I know is fairly accurate because the numbers also match another external (inline on coax between transmitter and antenna) freq. counter that I have and another radio station's report of the frequency that I'm transmitting on are all the same numbers.. My radio is transmitting and receiving on channel 1 at 26.967 MHZ instead of 26.965 MHZ.. Likewise there is a .002 MHZ difference on the rest of the AM & SSB channels as well. I'm planning on unlocking and extending the clarifier which will require a PLL alignment when completed. Either way the radio needs a PLL alignment... So.... I'm wondering if I can perform the PLL alignment using the frequency counters that I now have without having to buy another one that's capable of connecting to TP3 on the PCB?
My question is:
The 1st step:
Can I adjust the AM frequency by setting the radio to CH 1, AM, RX mode, clarifier control to center detent, and adjust L20 until I get 26.965 MHZ shown on radio's onboard freq. counter? I'll also compare these numbers to the other coaxial external frequency counter which will be in line??
The 2nd step:
I will set USB freq. by setting the radio to CH 1, USB mode, clarifier control to center detent. Whistle while transmitting on TX and adjust L21 until the frequency reads 26.965 MHZ.
The 3rd step:
Iwill set LSB freq. by setting the radio to CH 1, LSB mode, clarifier control to center detent. Whistle while transmitting on TX and adjust L22 until I get 26.965 MHZ...
Can anyone tell me if this idea will work or do I need to purchase another expensive freq. counter so I can use the numbers and test points that CB Tricks show to use?? Thanks for any help you can offer.... SD002
