I have come across a CD44 rotor that is 8 wire and have the opportunity to get a CDE H-IV controller box that is also 8 wire. I know the H-IV controller is to work with the CD45 rotor but does anyone know if it will operate the CD44 rotor properly? 73's Richard

Thank you Handy Andy I love the knowledge you share. I am working on a Robyn 520D. A beautiful garage find. I cleaned it up recapped it and she fired up. I started from the synthesizer alignment procedures in SAMS manual and worked all the way until the 100% mod in TX alignment. The...

I am having an issue with cb and the oscilloscope to get a clean sign wave. Could this due to the ALC/AMC modification? I am currently working on a Robyn 520D I don't see any modulation modifications that stand out except diode D46 lifted.

Good morning, Can someone please explain what exactly these two circuits do? All I know about them is people do mods to them to get/show more swing and I know that's not good. I'm not wanting to do mods to these circuits I just want to understand what it is they actually do. Is the mic limiter...

Thank you so much for your help in identifying the radio inside. We have Sams to offer our service manuals do you know if there is a similar Co for the export radio's? I did find a Owners Manual for the Jopix so this would be the same for the NS9500. Stated in black and white on PG 23 its a NS9500.

Update.. What I have been able to find on the web is a Galaxy Saturn SSB Base. The board in that unit is the same board but some of the components are different. Adjustable pots and the resistor numbering are the same but the capacitors numbering is different. Along with the process of trying...

Hi Bob, No that is not me but it sounds like a great second hobby! 73

Hi there, I just received a Super Jopix 3000b 10m base transceiver. The gentleman who gave it to me said when he plugged it in he smelled smoke and then shut it down. I did find that the reverse protection diode was bad (burnt the board). I replaced the diode and now the radio powers up. This...

Hi David, When I read the Sams it doesn't actually say TX like in the other procedures before this one so I was not. I was thinking idle current meant while power was on but not TX. I was not keying the mic. Its works now. Thank you...this was an easy one! Live and learn. 73

Hello again! I have been able to bring this Teaberry back to life with your guy's help. I have a situation now that doesn't seem to make sense. To me anyway! I should mention a couple of things.. Xtra channel and clarifier lock have been performed on this unit. It is up and running with full...

O my!!! I guess when I was trying the tx alignment the other day before I changed the caps I adjusted L36 for max RF. Just now tried it again and guess what apparently I turned it down? Lol my power is back. Live and learn. Anyway this has been a great journey along the way, from dead to walking...

Thanks again for helping me along. I have already changed the caps 191,162 and 215 I changed those a couple days ago. They were all bad. TR#25&34 have correct voltages so I think the switch and trace are ok. Is that correct or am I missing something?

I tried working on this step of the alignment process. but when adjusting L26,27,28,29 - no response when moving the slug. L36 did show a response and was able to adjust. Any thoughts to help lead me in the right direction? For my first attempt of troubleshooting a cb this was prob not the...

Update - Found crystal socket on the xtra channel board loose, reflowed. Checked TA7222P AF output - voltages were bad. Replaced and now have audio. Still have an issue with voltage at pin#2 manual states 3v but my reading is 6.63v. Pin#5 & 6 states 1.8v my readings are 1.15v on each. Didn't...

Update - I have been able to complete the PLL alignment according to the SAMS manual. Now I have TX/RX but no audio. The RF meter is moving showing incoming signal but no audio. In TX I have no output according to the external watt meter but I can hear my modulation in a nearby cb radio but only...

D25 tested good .6 D44 tested good .6 OK - D25 lifted - test good at 0.6 D44 lifted - test good at 0.59 TR45 - pulled out test good 0.63 both legs TR37 - pulled out test good 0.61 both legs TR37 - voltages while D25 lifted B - RX 7.73v TX 0.7 v C - RX 13.8v TX 58.8 mV E - RX 7.52 TX...

Yes I do have a frequency counter.

Thank you, Still a great deal. I placed my 1st order thru someone else and still haven't received it then I decided to try order from you. Its great that I just placed the order yesterday and you will be sending out on Monday. Thanks again!

While I'm still waiting for my new caps to arrive I have read this string over again. I see where I said I was going to wait to lift D25 until I had it recapped. Since I'm still waiting I have put in a new 10.240 Xtal, that didn't change any symptoms but I did lift D25 and it did restore TX LED...

TR19 voltages are close - TR24 voltages are close TR23 base is 1.44 Collector is 8 but the emitter is 9.5v should be 0.83 My question to you guys is this...is the manual correct or do I have an issue with the C-124 (.01cap) or do you think it would be with the R128 (1000ohm) ?
