I was wondering if anyone has information about receiving weather Satellites. I have the A.R.R.L. Weather Satellite Handbook but its dated 1994 and is rather limited. I would like to know what freq.'s to find them on etc.
Thanks in advance! 73's

Google "receiving NOAA weather satellites"...the frequencies are in the 137 and 1600 mhz area

I'm having a problem with my 5500 after a thunderstorm. What is happening is that the rotor works manually, but doesn't display az and el information on the control box. Also when I try to use computer control it goes all the way to stop in both azimuth and elevation. I'm thinking this might be in the control box, as both az and el are doing the same thing, the control box being the single point of failure. Did anyone ever have this problem? How can I diagnosis what chip might be at fault without a schematic. I vaguely remember having this same problem after a close lightning strike with my prior az el Yaesu box about 14 years ago but don't remember what chip I swapped out, or how I determined which one was at fault. This getting old thing really sucks. Any help would be appreciated.

Hi Jeff,
I had an indication problem on my 5500 many years ago....
I opened the rotor and discovered that there was a cold solder joint on of the pot contacts...a proper solder joint solved the problem...an easy one to check first......

Hi Jeff, KB2M
I have sent to you the schematic diagram for the G5500 but the message bounced back to me because your @comcast.net don't match with my @tin.it
By the way and first of all check if you have 5 volt DC between studs A1 and A3 and between studs E1 and E3 on the rear of control box.
If you don't have 5 volts DC probably the regulator Q2 7806C is gone.
If you have another email address please let me know and I will try again to send you the schematic diagram.

Thanks for all the replies on my 5500 rotor problem! I had some time tonite to work on it and here's what I got. On both a1 a3, and e1 e3 pairs I'm reading only 1.0 volts. Between a2 a3 , and e2 e3 pairs I see only .5 volts at half range, IE an elevation of 90 degrees = a reading of .5 volts. I'm going to order a new Q2 UA7806C and this should do it. Only question I have is why Q2 failed to only output 1 volt, don't they usually fail and output 0 volts? I'm thinking it might be something else in the circuit feeding power to Q2. If so I will work this further when I actually take the rotor box apart with the new Q2 in hand. One other thing, I wish I can find all my components' I boxed up when I moved. I bet I have 10 of these in stock :) Thanks again for all the help guys, the electronic copy of the manual was a big help as I can't find my copy....

Hi Jeff, KB2M
Disconnect A1 and E1 from the rear of control box and measure the voltage between input and ground at the imput of voltage regulator Q2 7806C and it must be about 12 volt DC.
Since the voltage you measured at the output of Q2 7806C is lover than 5 volt DC i.e about 1 volt DC disconnect C9 , 0.01 uF and measure again.
If the voltage is still lover than 5 volt DC than the voltage regulatore Q2 7806C is gone and must replaced.
Have fun.
