I was reading through my manual again to see what all was covered, & on page two in the BASE ASSEMBLY section it states: “Note: Overall length is the distance from the top of part T01P to the bottom of part BA1P.” The top of T01P would be the very top of the antenna as T01P is the very top...

That makes sense Sonwatcher; seeing that diagram with the arrow pointing to the bottom, which leads me to now believe the VERY bottom of the antenna as shown by the arrow. Why don’t they just state the very bottom of the antenna or very bottom of the base assembly, why even bother mentioning...

Marconi, That always confused the heck out of me! I got my antenna somewhere around 10 years ago & I was not sure what they were referring to when they stated “below the hole for mounting bracket C13P”, I was not sure if they meant the VERY bottom of the antenna, or just below the hole for...

I appreciate the info guys! Is the Delron or Delrin used in both versions? Different types of it made, like different grades? Or does one use that material & one use a different type. I really do appreciate the info on it as I was very curious for some reason about the differences between...

Hi Sonwatcher, That’s interesting. That insulator always reminded me of black PVC pipe, haha, but I suppose it is probably something different. It may be hard to distinguish between the two if that’s the main difference, unless it is a different diameter or thickness tubing but I’d imagine it...

Hello everyone! I have wanted to ask this for a long time now. Probably a silly question, but figured I would ask anyhow. How can you tell a Maco Alpha V5/8 apart from the V5/8 V5000? I am assuming the wire that connects the SO-239 to the matching coil might be different gauges between...

loosecannon, I cannot specify any particular brands to look out for on the ones that were not made properly, but I remember reading something about that some time ago. I use nichicon often as well; they have been around for a long time & I have never had a problem with them. There may be...

I too thought a replacement capacitor kit for the 2510 would be a good idea when I was putting a list together for all the caps I needed since I wanted to do mine, would save some people a little time. I was not sure if it would be a big seller, but I thought some people may be interested...

Hello mechanic, If its “jumpy” when adjusting VR117 it sounds like it is dirty & needs cleaned or replaced. I’d start with that especially if the S-meter readings seem normal & steady. The 2510 variable pots may be hard to clean though the way there made, I have never cleaned them before...

I definitely want to go through some of my radios, especially the older ones like my 2510’s, & considering the bad caps that I, and many other people have found in these radios, it just seems appropriate as the rest (or most) of them are likely towards the end of there life as well. There...

Yeah, I’ll be curious to hear what the problem is, & like you say, it may come in handy for someone with similar problems in the future! There nice radios & I hope you get yours up & running again! Take care, pioneer621

Hello, One of my HR2510’s gave me a similar problem with the radio turning on, but no display on the screen. I suspected bad capacitors as I already had to change other caps in some of my 2510’s & it seems to be common with the age of these things. The one that had this problem was the one...

I like the looks of the radio. Would love to see one in person to see how the display looked up close, & some of the extra features sound cool. I think the display looks very nice, especially seeing large pics at cbtricks. Hopefully they do not have any problems with the display & it lasts a...

Loosecannon, This will likely continue to be a slow project for me as well. I started playing with the MOSFET in the radio probably two years ago & Shockwaves thread kind of got me playing with it again, but progress will probably continue off & on as I get time. I too will try to keep up on...

Playing with the resistor values may gain you a little more power; going from the 230K to the 330K may give you a watt or two, worth a shot playing with. As for the 1-MEG resistor; all that is for is biasing the MOSFET, & the value may need fine tuned to get you the proper voltage for your...

Actually I went ahead & replaced Q24 last night. I was sitting there looking at the radio while it was on the bench & figured I go ahead & change it out. Did you add the 33K resistor when you did the EKL mod? If so, try the mod without that resistor installed & see if it works.

Here is how mine is currently wired & seems to be “in phase” in my GRANT XL like this. During some more testing I noticed it wanting to break up every so often again, so I added yet another 1000uf cap making it 2000uf & it has not done that since & the audio sounds fine, we will see if that...

I had to get my flashlight out to take a look in there, but whoever worked on this radio before I got it, cut TR-24 (actually Q-24 in the GRANT XL). I have always meant to replace it, but never seem to get around to it, I just try to monitor my audio & make sure the MIC GAIN is set right when...

Loosecannon, I just like to experiment with this stuff & what ever values I used is probably what worked best at the time & what I had on hand, although I have so many old parts boards from various electronics I could have made the exact parts from the EKL sheet, & I know I probably did...

Shockwave, I am not sure the difference between the IRF520 & ERF2030 myself, I mostly use the IRF520, but have used the ERF2030 in the Cobra 29 radios & the performance was about the same between the two from my testing, but again, I am not sure the main differences. Yes, good idea...
