Yes, let us all know. I was thinking of possibly getting a 99V.
Whats the bad scoop you have on them???

Min

Channel 40 and frequency counter readout.

Thanks alot Rick. I did the clarifier your way and all is good now.

Cheers

Min

Rick, I have just done the Clarifier mod the way you described except for R175- change to 1K. Just cause I dont have any on hand and will have to wait till tommorrow for the shops to open. The clarifier still slides great and I can now get it on frequency. What is R175 for? Does it have to be change...

Min

Its been a while now UncleT, hows the progress comming along???
Surely by now you`ve gotten the parts needed.

Min

save your money and invest it in another galaxy or something. Not the 200.

Here is a link to something I just found for ya, Not sure what kind of alignment you are wanting to do.

Min

All I have to do know is the clarifier mod, which I will be doing Ricks way. This should fix the slight off frequency problem.

Then all is done.

Min

Channel -79= 26.175MHz

Min

Channel 108- 28.085MHz

Min

7805 Regulator with a heap of Silicon Heat Transfer Compound and a decent heat-sink aswell.

Min

The Mod Board Installed

Min

here is a smaller pic of the PC-409

Min

Yes the regulator is getting hot when in RX. How do I check if those caps are leaking? I still cant find TP1. I found this in the cobra 148 with no problems but in this grant I cant. Any ideas as to where it is. I can post a pic of my board and you could circle where it shouild be. I have attached a...

And thanks to you too

Min

Mine already has the Japan pll. Also im not to concerened right now about frequency expansion. Trying to fix a problem. Thanks for the info though.

Min

Good to hear.

Min

Back on track/subject, thats good to see. We are all always thinking and learning here.

Min

For the likes of me, I cannot find TP1 anywhere. I found it on the schematic but cant find it in the radio. When the voltage reg failed the last time I cant say why, as I brought it like that. And the repeated failure this time, I`m sure it happened in RX mode. There are no toys installed, radio is ...

I am currently do 2 radio with The Mod. President P400 & Uniden Grant (silver face). I will post pics once they are completed. i can't wait to see them done...is the mod hard to install in the 2000?? Sorry frogman296, I just noticed that I didn`t answer your question. I haven`t done 1 to a cobr...

Hi Rick, back to this grant again. Board No #PC-409AC and it has the MB8719pll. I have tryed to install a frequency mod board into it and it is off frequency by 1 channel. eg: display shows ch 30 and when keyed up the frequency counter will show 27.295. I have changed the crystal to a 11.1125MHz as ...

Min

Hi, how do I go about tunning the frequency for AM/SSB. I have just installed a frequency mod into it and would like to tune it up now. I dont have a scope, but I do have a frequency counter, digital voltmeter, multimeter, power/swr meter and all the proper plastic tunning screwdrivers. The radio is...

Min

It hasn`t left no negative impact on the forum. He should make an appolagy to you and possibly all members of the forum. As far as an instant ban, I would say no. But that would of been the first and last chance. Next outbreak would result in a no questions asked, instant ban. But then again, thats ...

Min

No, that is abit to extreme. He should just get a PM from them telling him to just chill and enjoy the forum and that this kind of behaviour is not exceptable. And that this will be a First and final warning. And if further outbreaks/rudness or attitude happen you will be banned. Well thats what I w...

Min

hotshot best you be careful what you say. Dont wont to get banned from here do you? This is a forum for learning about radios in all aspects and sharing knowledge. Rick for 1, is a person that has alot when it comes to cb radio and he does help alot of people. He is much appreciated through out the...

Min

Rick already said to use pin 1 instead of pin 3. Pin 1 runs a constant 8volts, so the answer to your question is YES. Use pin 1.

Min

Hi Hammer1, and welcome to the forum

Min

Rick or nomadradio, I will be hopfully unlocking my clarifier later today. The radio is a Cobra 148GTL #PC-412AD.

What is the best method for the most slide and for it to sit at 12 o`clock???

Min

Rick, with the clarifier mod your way. You use just the red wire and not the orange. Why do all the other mods use the orange 1 as well.

Min

What is so good about the ERF2030 Final Upgrades???

Min

Rick, are you able to redraw full radio schmatics??? If yes, I`d love for you to do some for me. Your redraws comes up so nice and clear and easy to read. I was just asking cos I have seen a few 148`s come through with them wired to pin 3 and a lot of them to pin 1. Just wasn`t sure what the differe...

Min

Rick, what is the difference from pin 1 & 3
Pin 1 is Vout-0= voltage output
Pin 3 is Vref... what is Vref???

I`m looking at the pdf file for the MB3756 and I dont see anything about Vref- pin 3.

Min

Thanks for that guys, I was looking at the DX99V. Will look into it a little more. I was thinking of the 959 just cos its on the cheap side and the fact that it would look nice with all blue or green leds.

Min

Hi all, I`m from Australia and i`m thinking about get one of these in the start of the new year. I just want to know if people have had problems with them, if any. What where they and how did you fix it. Also how reliable are they? Any comments on it , Good or Bad. I`d like more info so I can find o...

Min

sorry, just went to the link you provided. Read the info just under the pic.
It says "spdt on-off-on switch"

I was right.

Min

I would have to say "on, off, on"
switch up 10kc up
center off (normal freq)
switch down 10kc down.

but wait for a few replies as I could be wrong as I have not done 1 of these yet. But it sounds pretty right to me.

Min

I have seen this else where before. I wouldn`t recomend them to anyone, but I will end up getting one for myself to have a fiddle with. Maybe we could make some improvements to the unit and make them worth having.

Min

As much as I dont like them, early next year I will purchase one for myself so I can see how good they really are and to see for myself the difference between them both. Well with the newer ones I know that the mod board I`d like to put in it wont work as it is the rci and not MB8719. Even if I wher...

Min

well i have a friend that owns one and he is for ever whining about it, and as for modifiaction eg channels. there not as good as the older ones. Not to say that it also has a rci8719 chip that is crap.

Min

no problem

Min

best you look around, I`m in Australia and I have just purchased a older style 148 for just over $100 and thats including postage from th US. There are plenty of them going around, save your hard earned money and get yourself an older style. Alot more reliable. Do more reading on the newer style one...

they give about 5 watts extra...if you shine them, you get 6 watts zodiac.

From what I hear, if you mount the top cover upside down you`ll gain approx 12watts

This amp will cover 25-30MHz (europe) NO MOD

here is a link for this amp.

Min

just my opinion, your better off and waiting till you can find a good older style Cobra 148GTL. From what I hear the newer ones aren`t all that good.

But like I said, thats what I hear and also just my opinion.

Min

well I see the link did work.

Min

not sure if the link will work but give it ago. Its a pdf file for the trc-457.
