I have done that with car parts. I have parts for car's that neither myself or my family owns any more. LOL When I do get rid of something it never fails a few years latter I think of a way I could have used that very part. LOL
So I had $900+ in my RF Parts cart. I whittled it down to $174 or so. They need a save for latter button!
The high dollar parts I could recall exactly what I wanted those for it is the tiny $2 and $1 transistors I had absolutely no clue why they where in the cart! Those are the parts though I...
I pulled the trigger on my RF Parts cart after scalling it down from $900+ down to $150. Som restraint is in order.
Now I need to address Mouser and Digi-Key although some of those parts are for high end audio repairs to vintage home audio 1970's through 1990. I have a reel to reel that I need...
I was just thinking the channel board for Galaxy's all use radio's with 145106 PLL's I think and the 979 uses an RCI8719. I should of thought of that before ordering. Ooops. Well this just means I need another Galaxy now! LOL I am not going to build a bread board with socket to break out and...
Have you checked the power in your home and at the power service pole?
Any neighbors with solar panels and cheap inverters?
Does it get quite when the power goes out indicating a bad pole transformer?
A lot of old Fords or Harley Davidsons running around your area?
The appliances in your...
My memories from about age 20 down to about age 6 are as clear today in my mind as if they where yesterday. Before the age of 5 sketchy at best and post 25 or 26 not super clear. Between 6 and 20 years old though it is like watching a DVD I can rewind and see and hear probably 75%.
Thanks to...
Nomadradio Glad you liked that! I am not against them I am just not into someone urinating in my face and telling me it is raining! Be honest! LOL
I never argue with my priest, surgeon, or plumber and I do not lie to them. I kind of expect the same in kind!
You remind me on my wife and one of my 3 sons. They know what they like and do not like but do not ask them to explain it to you in a way that would make sense or allow one to predict future outcomes. LOL
I can kind of work with overly compressed! LOL
Yes but what did you not like. I to have a radio from John Mahoney a President Lincoln. I got a SP1-a from himn but did not have him install it in that radio. So just saying you did not like it is rather weak statement from someone with your experince. You might as well say "I did not like a...
Do keep in mind I am not trying to insult anyone! I am trying to get people to actualy put in some effort and respond like they would for less covered mod's! It is pathetic how little has been writen about this cheap, widely available modification offered by so many.
I got mine in 1991 as a senior in high school. I graduated in 1992 from Bradwell Institute in Hinesvile Georgia home to Ft. Stewart 3rd ID. Savanaha Ga and Richmond Hill is right next to this area as is Hilton Head. My friend and technician was Fred Ballintine of Hinesvile Electronic Repair...
So again experts what makes up the CP-1 and MD-1 parts wise? What are they doing? How does it do what it is doing? Why should anyone want or not want what it is doing? Why do you like it? Why do you not like? Can it be improved upon? How can it be improved upon?
Why has it been left alone and...
A strong wind blows out non-rf mosfets. SWR of 1.5 and pop! Mosfet finals not designed specificly for RF are garbage and have been garbage since day one. Sure they make power especialy PEP power and they make money for those that do the mod but that is about the best that can be said for them...
While your in there replace all 3 voltage regulators they are identical. You normaly upgrade them.
I am not saying that is the issue either just saying while you are there!
Nothing like details about what it does and how it does it or why anyone likes it or does not like.
When you try to research Top Gun MD-1 or CP-1 all you get is "Top Gun Good" or "Top Gun Bad".....
You can find 300 pages on NPC mod of a Cobra 29 but can not even get a paragraph on either of...
Sorry to bring this thread back to life. A lot of very basic and key info is missing about this device.
I am very familar with the SP1-a from decades long ago. It is a huge shielded box the CP-1 is smaller than a USA postage stamp about 1/2 as big and not at all shielded.
So is this device...
