I know this is old, but if part of your question is why it was removed, the answer is in the title. You can't sale a single brand in a listing and list another brand/s. I got busted by ebay for this years ago. If you are selling a Vertex VX-2200, you can't have ICOM, Motorola, Kenwood or any...

yes...7.5v.

he will not have any voltage at d24....he has none coming out of the clarifier to get to d24.

in that case it is obvious now that you have something pulling the voltage down on the output line. this can burn your new clarifier up as well. have you ohmed the output line out with ground? if you have a very low resistance to ground, then you next have to find where that low resistance is on...

i wasn't coming down on you, talking $hi! to you, or anything like that at all. and i was not asking for thanks, although i do appreciate that. i was only trying to steer you. you already found the problem, you just did/do no realize it. if you do not have an output voltage from the...

you shouldn't need other suggestions. you found the problem yourself. lets look at this logically. if i could trouble shoot your radio without seeing it....then you should be able to pick it up from here. you have 2 out of 3 of things i listed for the clarifier. you have the input voltage...

neither xtal can be suspected or tx would be off as well. so do not replace them. it is something in the rx steering section of the clarifier. i would suspect a diode is not turning on like it should and allowing the rx voltage to flow thru the clarifier. it could be a bad solder connection...

yep, that 'blob' was the high resistance i was talking about choking the current to the radio. and you can bet your radio that fuse holder melted when you reverse polarized it. i didn't even think about the fuse holder...i'm glad you did.

i would open it up and look for bad power connections or power connections that were damaged when the radio was reverse polarized. just because it recently started this behavior does not mean it is not related to that incident. you'd be suprised at how many times we have seen a past event...

we are not a parts dealer. the parts dealers are on rangers website, and may be on the list they emailed you. as for the transformer, we have never had one go bad. what i was saying is just because you hear the transformer, that alone does not mean the power supply is working. the...

the power supplies have a history of failing. just because the transformer hums does not mean the power supply is operating.

those are the irf's we use....but that has nothing to do with replacing 520's with 2030's. when we have dropped 2030's in circuits that were designed for the 520's we have had problems more times than not. with ssb capable radios we always had problems. you can't see it with a wattmeter...

they are not the same device. take any radio that comes factory with the 520 and substitute the 520 with the 2030. in other words, remove the 520's and replace with 2030's. then look at the output with a scope. you will see the 2030 is not stable in a circuit designed for the 520 (especially at...

actually, underdriving an amp can cause damage. underdrive can cause the amp to break into parasitic oscillations that can destroy the transistors.

mistake i just realized i made a mistake. for some reason i was thinking these were listed by paul zeppa from rf imaging. in either case you'll be fine ordering 1 of these monitors.

which monitor on ebay? can u give a link so i can check it out?

here you go http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=330223309608&ssPageName=STRK:MEWA:IT&ih=014 this is almost exactly the same as the hp8920 service monitors. the main difference is that hp8924 was designed for cdma use (cell phone). it also has another row of buttons and...

most of tv channels 52-69 are being auctioned off. where do you think the gov. is getting the money to give each house the 2 $40 coupons for converter boxes? at last count in feb., the bidding was up to 19 billion dollars. the gov. was only hoping for 12 billion dollars. 24mhz of this...

to be honest, i was always under the impression that this was not legal myself. that was until i went to a p25 work shop 2 years ago. i also found that i was not alone with this assumption. many dealers also thought this was not legal. just like the assumption that it is illegal for a vhf ht...

while i don't know these radios, i have never seen a vhf/uhf radio where u could not turn the scrambler and ani functions off. actually i have never seen a uhf/vhf radio come with these functions active from the factory. you must activate both features with programming software. the 'built...
