Here we take a look at the E-Reon Powerblast 300 and start to build it into a nice protective case with heatsink and fans, PART 2.

Hi there i have seen people place a small block of rubber inbetween the heat sink fans and screw in to the rubber expanding the rubber and securing the fan.I am sure you will come up with a good way to attach the fan you are a very resourceful chap.Thanks for the video and have a great day and all the best to you and your family.
can it cook ramen
EME with that amplifier and an IC 905 🙂
Really interesting series of videos Matt. Very much looking forward to the next installment!
I understand you're not gonna be running it at full power but one wrong move and you can fry QO-100's transponders…
I've been doing SSB on QO with barely 5watts of power and RTTY with 0.5 watt and for DATV 30watts is known to be more than enough.
You should put ferrite beads on each wire that passes through the case wall. Make sure you choose a ferrite mix that works at 2.4 GHz…
Why are you using a symbol for ionizing radiation?
i'd fuse the power in because you don't know what your supply will be in the future prevent accidental damage .. would it be worth putting ferrite beads on the rf patches and a inbuilt tuner .. i don't know how 2.4 works .. also a grounding terminal?
Great job Matt!
Hi,do u use cpu cooling paste? I would do;)
Progress. How are you cooling the inside? Fan blowing onto the pallet perhaps?
Good that you have the circulator if you put it into an antenna.
I would advise adding a fuse and an idiot diode in case you swap the polarity by mistake.
The reason we need so much headroom is because of the peak-mean ratio of the signal and requirement to not generate intermods. For DATV these are often referred to as shoulders. They interfere with the adjacent channel, so need to be kept low. Typically 10-30% of the maximum is what you can expect to extract cleanly, without special techniques like pre-distortion, so a 300W pallet is well suited to a 50W DATV PA for QO100. This is why there may be a pair of 160W devices in a 30W cellular base station amplifier and it means you can extract much more power if you don't require the linearity, so retired cellular base station and DVBT amplifiers they make nice high power 13cm and 70cm PAs.
Observation: Are you concerned with the possibility of electrolysis occurring with all the dissimilar metals and the amount of power that will be present. Probably won’t be a problem at first but if there’s any humidity, it may happen down the road.
Use rubber mounting from a dvd drive to allow your fans to float and reduce transferee vibration
At lower power the amplifier is not efficient.
Hi. Are you sure 12V converter would not create RF noise inside? Also, would be nice to see how you've connected semi-rigid cables to N sockets. It looks very neat.
Thanks for all your great videos.
Are you sure the buck converter will not cause rf interferance?
If the fans are 12V then can you wire them in series across the 24 volt supply?
Nice build quality! Stay safe!
Your microphone sounds great and I’m looking forward to the amplifier working 73s
Thanks for the video!!
