    Sirio 827 base antennae issue

    So it's been awhile since the last post on this situation. Well I'm convinced it's just that Texas Star is now total crap. Steer clear of these amps as they are now total crap. I have alot of respect for Mike and I know he knows these amps but he is in denial just as Texas Star is as a company...

    Browning Mark 3 receiver drift fix.

    Just a quick update on the state of this repair. What I ended up finding was that my major drifting issue was with the main tuning dial itself. Just years of oxidation that took a lot more elbow grease with a fine burnishing stick and some D5 cleaning the contacts at the capacitor shaft as you...

    Browning Mark 3 receiver drift fix.

    I can tune that frequency in on my old Yaesu FT101 receiver. I will test the mechanical oscillator link tonight using that method. Thanks for that. I am also not 100% sure now if my new C50 trimmer replacement that I put in at the beginning of this whole thing was actually bad from the get go. I...

    Browning Mark 3 receiver drift fix.

    I haven't noticed any particular skittishness in the tuning dial itself but I will certainly give it a real good cleaning this evening. I've gotten myself some white nylon string from the hardware store this morning and I have some 99% Isopropyl so we'll see if it helps or not. Maybe some D5...

    Browning Mark 3 receiver drift fix.

    Well, it appears that I raised the victory flag too soon. The drifting reciever is back at it. Uhhg!! It seemed to hold frequency for a couple of rag chewing sessions and then it started jumping around again this afternoon. At this point I'm hoping Nomad has the capacity to take this girl in for...

    Browning Mark 3 receiver drift fix.

    Sorry it took so long to report back but here it is. I completed Nomads mod and, holy crap, my bird once again can hear!!! Thank you Chris from the bottom of my heart. You are the man!! After carefully completing the mod and making sure that my 5V signal wire was not causing stray capacitance...

    Browning Mark 3 receiver drift fix.

    Excellent. I will complete the mod this evening after work and report back the results. BTW my Mark 3 does not have the black wire attached to SW2 and it does not appear that anything else had ever been soldered to the open lugs of SW2. That being said, my dial light has never shut off when...

    Browning Mark 3 receiver drift fix.

    So for me to complete the mod to eliminate C51A and C52B from SW2 with my existing receiver, having both CB and HF band, I would make the changes as you stated above but leave the long white/red wire to V3 pin 2 intact? One of thing that I've discovered while poking around is that if I move the...

    I do understand he is a busy guy. He has been of great help to me and many others here, so I too am very grateful for all of his wisdom. Just trying to give clear pics to make things easier to see. 73 Tom

    Browning Mark 3 receiver drift fix.

    A better look at where the "extra" white/red connects to SW2 and to pin 2 of V3.

    Browning Mark 3 receiver drift fix.

    Thanks for this lost mod. I notice that my receiver has some differences from the one shown in your photos. I have an extra white/red wire which leads back to V3. I also do not have any black wire attached to any lugs as your photo shows. In my photo, D52B has been removed. The xtal is also...

    Astatic 575m6 versions ?

    A little off topic but does anyone have some advice about how to take the board out of these 575m6 mics? How do you get the sliders past the cut outs to remove the board. I don't want to break the plastic by trying to pry it out. Any help is appreciated.

    Cobra 148 GTL mod

    Very good explanation Andy. Once again you've definitely help me wrap my head around something that I couldn't understand. I also just read what you posted in the other forum on the PC-122 clarifier. Another great little article related to this topic. Thanks again!! Tom

    Cobra 148 GTL mod

    Once again Andy thanks for all the detailed info. So I performed the mod as Switch Kit suggested and it works perfectly. One question I do have that you may be able to clarify...Switch Kit recommends to add D52 in line with the white wire when connected to the 8V constant supply to improve...
