I just wanted to post a quick update about where I am at the moment. Guitar_199 hooked me up with some instructions on how to build an rf sniffer and how to use it with the VNA to check the oscillators. I was also able to max their output or align their output across all 23 channels. As it...

No oscilloscope but I do have a frequency counter. I really, really wish I had a scope at the moment lol! Thanks, Jacob

No luck with the alignment. My original method from two days ago didn't work (output went to 0) and attempting the other method last night netted the same result. Jacob

OK perfect. I'll give it another go with the narrower bandpass tonight. I'll make sure I use more markers to show the band edges. I should have done that last night but it didn't cross my mind. I'd like to confirm that I aligned it correctly so let me describe the process to make sure my...

Dmans, Thanks again for the VNA lead. I ran through the different adjustments with the VNA and I think I have them dialed in. Let me know if you think they look correct. I do have a question about the crystal adjustments for the 4 crystals starting with 8xxx. I could not get them centered. The...

BJ, I would gladly take 3 watts swinging 8. The Owner's manual says 1.6 swinging 10 but even 1.6 swinging 8 would good. I have a Sonar FS-23 that keys 2.5 and swings 5 and it's killing the Regency right now. There's definitely something up with the Regency. Right now it keys .75 and swings 1.5...

Appreciate it Dmans! I'll take a look there next. Jacob

Dmans, Here are the values. I've also included 2 pics. V8 Pin 9 Receive : 16.2vdc Transmit : 17.7vdc After R55 Receive : 14.7vdc Transmit : 16vdc Blue/white Transformer Receive: 208vdc Transmit : 10.7vdc Primary Modulation Trans wires Brown (V9) Receive : 304vdc, Transmit : 303vdc Blue...

I haven't actually checked the value at V9/V10 during transmit. I can get that value. I've only done it during receive. As for the Sam's. It's so wonky for this radio it's amazing. CB-13 is more accurate for the most part however there are things on the receive side that are wrong in CB-13 but...

Just to add. @guitar_199 requested that I compare values to a working Sonar FS-23 that I have. It follows the same pattern as the Regency where the grid goes negative during transmit. Here are the results: "Interesting note on the Sonar. Pin 2 of V13 (final amp 6BQ5) on the final tube is...

Dmans, Thank you for the information. I'll give the VNA a shot. That video is very helpful. Here are the current voltage and resistance values for the modulation trans and V9, V10 - 6AQ5 Output modulators. Values in parentheses are what I have and the value preceding it is what the Sam's calls...

Dmans, Nomadradio mentioned K-Trans IF transformers being a problem. There are 4 in the radio but they appear to be in the receive strip. Do you think this is a factor? I never got a response from Nomadradio. Thanks! Jacob

Dmans thank you for your reply. The voltage values at the tube pins appear to be correct and a new tube did not change anything. Is there something else that I should look at or try regarding V8 (6AN8)? I also have that nanovna but I haven't found any helpful videos regarding troubleshooting...

What causes the grid on a final output tube to go negative in respect to the cathode upon transmit and what would prevent this from happening? The reason for my question is that I have a Regency Range Gain that will only key .75 watts and swing to 1.5 watts rather than the 1.6 watts swinging to...

@nomadradio What are your thoughts on the placement of the the K-Trans cans and their interaction with transmit? I could really use some help. No luck with new 7.5MC crystals (though the frequency is tight and on point now) and a follow up alignment. I'm still getting positive voltage at the...

I can't do anything about the age aspect but what are your thoughts regarding NOS K-Trans IF transformers. Having not been exposed to heat what do you think the likelihood of success would be in regards to replacement? A temporary bandaid of sorts? Also please excuse my ignorance regarding the...

I think I've connected the dots...IF transformers. It does look like that's what is in there. What's the "known" problem with them? I think I stumbled across this issue in a post about an Olsen Sidebander and I just became aware that they're the same @#$^ing radio! FML! I think the plastic...

Please explain

Well no luck with the tuning. I ran through the tuning process as discussed and and can get no better than .5-.75 watt deadkey swinging to 1.5 watts. I've also tried 2 new 6AQ5's, 2 6AN8's and 3 different 12BH7 tubes with no more than the above output. I'm at a loss as to what to do next. I'm...
