FDA24N40F... Apparently this is the real part number of the restamped ERF9530. Well I intend to order one and find out.

No sir I would keep looking for the proper replacement that is not restamped and shouldn't cost no more than 5 dollars and guys like nomad and a few others already know exactly what it is and where to get it but cannot tell anyone due to an old gentlemen's agreement in the interest of not losing...

This guy is 100% right Andi have the experience to prove it and it happened just like he said, just as soon as I turned the power supply on the power supply went into protection almost immediately.

Even here in 2026 trucks is still the only place to have them in stock.

I recently aqquired one of these devices and expierianced what I feel is a little low on output when engaged, on my cobra 29 with amp on the carrier stays the same as if it's barefoot 3 watts then steady audio swing to 50 watts avg and this is the only change this amp has given me so far is act...

Pay no mind to this post I didn't know what I was talking about anyways, I'm still a dumbass tho I'm learning more everyday.

Those 505s are an audio monster aren't they and all it takes is turn the 2 variables inside all the way up oneis for AMC the other is for POWER and go with it. I have a 505 that peaks 30 watts no joke .

Because the 505 has a differant chassis in it that has a MOSFET transistor for itsfinal output and the 505 has 2 pots in it, one for AMC and the other for POWER. All u gotta do is turn both of those all the way up will really transform the radio into an audio monster peaking out around 30 watts...

I h open you didn't pay a whole lot to have the tune and alignment done because you can't tune or align it at all there's no tuning pots in it

I have to agree with you sir on what I'm seeing and I'm just applying common sense with past expieriance with experimenting with many differant antennas for 30+ years so my final decision about the gr-45 is just marketing hype selling crap that just looks cool because it's differant.

I had no issues from switching both driver and final to a 2sc1306 and a 2sc1307 and the 1307 has near identical specs as well, they worked fine in my cobra 29 without any additional butchering

If all those steps are necessary just to switch from one bipolar to another similar but not identical bipolar transistors in final output that's a little more radio butchering than it does to accomindate a MOSFET conversion. I'm gonna need to study more on this mod I can't decide how I feel...

He's absolutely right these uniden 980s are a waste of time really so hand that 980 to your kids and buy yourself a quality radio like a president McKinley or if 10 meter is your thing can't go wrong with Anytone 10 meter radios line the quad 6 ECT lots of power good sound all around tops .

I recently traded for a 980 and it looks and works like new except it does not transmit due to a blown final that I already pulled and checked with multimeter and it's shorted so I'm assuming this is a MOSFET transistor with no writing or marking on it just smooth darkness. Cannot find online...

I have several of these 7 ft skipshooter whips and the one in currently useing I had to cut off the tunable part of the top coil plus a little bit of the oil itself until I was left with a 6 inch loading coil on top for my swr to be 1.1 from 1 to 40. After I did this the skipshooter has...

My F**kin pinion they did just tellum dear old dad sent ya

I think I will purchase this amplifier from copper electronics right now

Mics wire up to this radio just fine as long as one knows to only use 3 wires on any after market mic no matter what kind or brand or power mic or not they all work. Modulation, Keysup, Ground, that's it.

My ares 2 has too much audio restriction with or without a power mic I gotta scream into my microphone and nobody can hear me
