2 pill vs Galaxy 98vhp

[yota167]

And yes I realize the 4 pill board on the galaxy will show more watts on a meter. I just said the Cobra with 2 pill would out talk it.

Hehehehehehene

Read the 4th and 5th line down it does not say anything about des transistors. The guy from ranger said it would not get as hot as the mosfets

They keep coming out blurry but anyway it is right from Rangers website and the radio that has the amp I am getting comes with 4 - 2sc2879 toshiba transistors.

[yota167]

Id bet if you opened it up you'd see DEI not Toshiba stamped on the transistors. Nothing wrong with them IF they were matched properly IMO. Remaining Supply is drying up on the red dots.

Maybe they have some old stock toshiba ones stil which would b awesome. I'd still take an external and a 25

[rosman6119]

What do you mean by remaining supply is drying up what is drying up.

The toshiba 2879's haven't been made for a long time. Hence they are drying up and getting expensive fast at that. I would imagine like other said poster that If opened the transistors will be 2sc2879 DEI transistors. It would be cool to get toshibas, but I am with 543, for what you will have spent on the radio and amp board you could have bought a decent export and a tnt600hd. That would do about 600-750 watts on SSB. Maybe a bit less on AM, but still over 400. But if you are dead set on this setup, make sure to have good ventilation under the amp board and a couple of good fans to keep it cool. And good luck.

Well here we go again why would it be any different then if I left the Galaxy 98vhp the way it is with the mosfets I thought they were more sensitive then the other type of finals the 2879 and the truck it is going in I have a 1.1-1.2 top to bottom SWR reading with the 98vhp right now and all I am doing is changing to what I thought everyone says are better finals am I wrong.

Just leave well enough alone. If you just can't be happy with it, sell it And buy something that's the proper drive wattage for a 4 transistor box. Seems like we are talking in circles here.....

I think you're right Yota. Round and Round. LOL
Anyhow:
There are some "new" Toshiba's out there but they aren't made by Toshiba. It's kinda up in the air but those are what Ranger were suspected of using last spring in their run and the previous years fall run. I've also heard as of late they also went to DEI. Might be the same company making both. Chinese either way. The company that makes the boards for Ranger also makes a lot of boards for my company. The price I gave was based on what guys are paying at the radio shops. They are not a bad board and would make a good amplifier if it was in a well ventilated box. Only real downfall to the board is if and when you pop a pill you may be able to replace them once but by the second time it happens the pads going to the trace will be in really bad shape if they are still there at all.
What I've trying to let you know Rosman, is what I went through with the same style radio. It's just my opinion and I hate to see someone throw good money away. If I had it to do all over again I would have went with a radio and separate amp, would have made life so much simpler. I was intrigued by the whole "all in one package" and the out of back watts. Saw it and said gotta have it. Had it for three months and smoked my first set of fets. Next set lasted 2 months.(I get long winded) Heard about the 4 pill board mod and ordered one. Got put on the waiting list. Me, I'm impatient so decided to start experimenting. From there it's an entire other, long boring story. I do have the complete Ranger board I ordered. Never used. Might use it one of these days when what I have in there now blows up.

Yes the 2879s are better for amplifying RF @ 27mhz than some switching fets that were not designed with RF in mind, they just happen to work. Your radio is the foundation of your signal. If it produces a dirty signal and you amplify dirt you just get more dirt. If you but 4 2879s on a heat sink about the size of a radio cover with poor airflow from some tiny internal fan it will get hot...if it don't get hot and you still see big watts you're transmitting a lot of junk. I have a galaxy 95t with 2 2290s from my export days. It it aligned per factory spec and I have modified the radio with an internal blower to keep it cooler. If I get long winded it will get hot. Making watts makes heat so you need a properly sized heat sink and airflow. Export radios are eye candy with bells and whistles and nothing more. A lot of times you aren't doing yourself any favors by amplifying the trash that comes out of one. Any experienced amp builder or tech worth his salt has witnessed something crazy happen when you put an amp behind an export and then watch it work fine with a legal CB behind it.

If you want an all in one package radio with a lot of features and a little punch an export is perfect. If you're more concerned with performance, have room for external amps, don't need all the channels, echo, and lights an export has nothing to offer. I do not ruin good radios with high power mods or mosfet conversions. I know some radios come with the 520 mosfets (and similar) these days and we have to live with that but don't hack up an old classic and make it worse. All you need is a mostly stock radio with strong loud modulation, an efficient antenna and how ever much amplifier you can run effectively.

[rosman6119]

Ok I am convinced so I will put the Galaxy 98vhp in my personal vehicle and leave it alone and I will put the Galaxy 939 with dual finals in my work truck and buy a pill box for the work truck do you have any suggestions on what kind to buy and what would work good with the galaxy939 dual final radio and I already have power cord ran to the battery with 8 gauge wire I don't want to have to replace that wire I would like to use it so I need an amp that will work with that wire please.

Good post Yota.............

[rosman6119]

I read the article yota but it still does not tell me what the best amps are out there to buy I just thought with all everyone's experience on here someone could just recommend a good brand I must be wrong so I went on YouTube and looked at A lot of reviews and I think I am leaning towards **Censored** or Dave made from what I read I can't really go wrong with either one so thanks for all the help guys.

[yota167]

I've had good luck with Texas Star amplifiers. You will need to convert them however as they are designed to be CW transmitters, not RF.

[1206FL]

Look into X-forceTNT line of amps. Dave mades are good as well. The tnt 600hd is a good 4 transistor amp. I own one and it works well. Get about 550-650 out of it, with about 50 watts of drive. Does well on SSB as well. Dave mades are probably a better amp, but to have the amp biased at least bias b and adding SSB components, they can get expensive.

**Edited by Bozo** - reason sent in PM.

[Deleted User 14541]

X2 on Davemade or xforce. If you dont use ssb don't worry about the ssb delay or biasing.

[rosman6119]

Ok thanks for the advice I should mention I am going with a 2 pill if that helps and my galaxy 939 does not have SSb so I will be happy with what power a 2 pill can do and I want to use the 8 gauge wire I already have installed in the truck so if I go with a davemade 2 pill will that work ok with the 8 gauge wire.

[Deleted User 14541]

Yeah the 2 pill will be fine with 8 awg. A 4 pill will run with it but there will be voltage drop. I've ran a 12 pill on 4 Awg but don't tell anybody. Your radio is a little hot (assuming it does 40-50 pep) for a 2 pill. If you go 2 pill don't get it biased and keep the deadkey out of the amp at around 50-75 watts. Pills aren't cheap these days. You might have to back the mic gain down if someone tells you it sounds bad.

[rosman6119]

Ok not sure what biased means and keep the dead key out of the box s if I take it to a CB shop should they now all that and what do you mean a little hot should I go with something other then a 2 pill but again remember it will have to work with the 8 gauge wire in the truck I don't want to bug the mechanics at my work to keep changing wire for me and thanks for the help.

[drdx]

Maybe I'm confused but doesn't you first post mention you already added a 2 pill amp? Why would anyone recommend an amp since you said you already have one?

-drdx

[1206FL]

Yes it does in fact state he has a 2 pill amp. I would recommend stepping up to at least a 4 pill and use the dual final 939. But even then conditions will play a big part on getting your name called as well as having your whole system to be as efficient as possible. Antenna is what I would look into. How tall is the current antenna on the work truck?

[yota167]

Dudes got a 450$ radio equipped with SSB, IMO a BIG straight pill Texas Star would be the way to go. That is if OP is wanting one for that radio, I can't keep up with the thread. So do you want a linear for the export 98vhp or the CB?

You said u already had a 2 pill in your first post. I'm confused.

[rosman6119]

Ok I will explain everything one last time this whole thing started because I put a 2 pill in my personal vehicle with my galaxy 939 that I have dual finals in I also have a galaxy 98vhp I bought for my work truck Which I thought had a lot of power now my radio in my car the 939 I am getting out as far as Texas with the 2 pill on it , now my galaxy 98 in my work truck I never got out that far with that radio so I started thinking and I called ranger radios to see if I could just by there amp board with the four sets of finals in them the 2879 's that they make four their radio because I was told it would fit inside the the galaxy 98 vhp and is an easy swap out because it is the same board as the 98vhp just more power and some people above in the thread told me I was crazy for doing that , that i sould just put my galaxy 939 in my work truck with an amp pill box see I can not put a pill box with the galaxy 98 vhp because I can not run more wire in my work truck I already have 8 gauge ran for the 98 vhp I can't run another one and I don't want to use the pill box now in my work truck with the 939 radio because it was built by someone I work with and I am not even sure it is made correctly so that's what happened in all the above comments so all I said was I would just put the galaxy 939 in my work truck and buy a good well made pill box for it and I would put the 98vhp in my car and leave it alone the whole goal is to get more power in my work truck and I need someone to tell me what type of pill box will work well with that dual final 939 radio please I was thinking just a good 2 pill so what do you think. I hope you could follow all that and sorry if it is confusing. And thank you to everyone for helping me.

Holy txt wall. Paragraphs would help.
