In need of schematics for a Palomar 900v. Thank you.

marveylus22

No problem Farmer.

r-240 is located in between c-190, and tr-50

Varctor is D35. Adding a 5.6uh choke to the anode will also increase slide range further.

marveylus22

did you try to turn up the mic? Also check yer wire conections. 73`s

marveylus22

Okay found it. Q37 had a bad solder connection.

marveylus22

Thought I had it, but not so fast. When I leave the radio on to long connected either to my power supply, or in my vehicle it shuts off. When you try to turn it on you hear a little pop in the speaker and no power. After disconnecting the power source the power will return to the radio. I have a goo...

It was on in the garage when I went to work this morning, now nothing. Any suggestions? Thank you.

marveylus22

add a jumper wire or SPST switch to the empty 2 holes on J10 (8v and RB). Its in the front of the radio, 1 inch behind the meter, just like all the Galaxy's. There aren't any controls on the radio for it, but I guess they just threw it in there for some reason. If you want a simple switch on the fro...

I tried to add photos of it but the site said I was spamming!!! Go figure!! I will attempt again here soon. It`s the same as the 959 949 but there is a ceramic disc cap added on the copper side of the added final.

Yep dual 2030`ed mine. PM me and I`ll set you up.

Got it realigned L-20

marveylus22

I have aGalaxy 919, and it is RX, and TXing off a little on all channels. Here is where it is at on channel 19 27.1856. What do you suggest that I do to align it with out a scope? I do have a freq counter it is the FC347. Any help would be appreciated. Thanks http://cbtricks.com/radios/galaxy/dx919/...

marveylus22

have you tried to adjust VR12?

marveylus22

Thank you sir. On which side banded or non banded?

marveylus22

I got it. Band goes to where the arrow points.

marveylus22

One more thing sir. With the front of the radio pointing towards you, and component side up which way does the banded end go? To the left or right?

marveylus22

Thank you sir.

marveylus22

Some one completely removed D-11 in a radio I just bought. What diode # is it to replace it? Thank you.

marveylus22

I was looking at the picture of the pcb, and schematics. It does look like the ELK 2030 mod can be done to this radio the same as the 494,959. I am I right on this? Thank you for your time.

marveylus22

Got it. Thank you sir.

marveylus22

How to explain this one... Okay here we go. When the radios on the receive is cracking at low volume, but when you turn the volume up it clears up. So I replaced the on/off squelch pot with a new one. It does the same thing. I notice the mic socket is a little worn, and I will also change that out. ...

Rick wrote:D8 is RF spike diode and should be left well alone. By jumping across the diode, you would gain about 0.7 of volt.

I know some site tell you remove it but the person who wrote such an article had very little knowledge and it is best to stay away from such sites.

Here here!!

marveylus22

Thanks Rick.......

marveylus22

Thanks for the help Joe. I did check the fuse on the pos, but neglected to look at the one on the neg. That was it. Thank you again for your help.

replace with these

tr 50 2sa1012, tr 51 2sb 817

PCB 3600 14B

I done the ERF 2030 mod, and when I powered it up it killed the power. I know I ended up grounding a solder trace, and I uninstalled the kit. I need to know where, and what I need to replace to get power back to the board. Thank you.

marveylus22

try tr50

marveylus22

Its not really a secret. It can be done. Good luck.

marveylus22

Never mind. I guess I an going blind! Thanks for stopping by.

marveylus22

Any info on this?

marveylus22

same as Cobra 29

PCB 3600 B

On the directions it says replace r-285 with 100 ohm resistor, but looking at the resistor chart for the PCB there is not a r-285. I was looking at the schematics, and it appears to be r-255. Am I right on this?

marveylus22

Or remove green wire at j-15, and add a mini toggle switch on the back of the radio.

First you may want to check the mic cable. Start with the lil things first.
