Cool down your HOT radio! - How to keep your G90 radio cool in style

[@MikeN2MAK]

I got the fan with the G90 from Radioddity a year and half ago. I don’t think I’ve used the radio without it. Really is a great accessory for it.

[@temporarilyoffline]

It solves a very necessary problem.

[@norrinradd8952]

The stand is worth it for the viewing angle and the powerpoles. It also does a great job at cooling. The engineering of this unit has evolved a bit since it's introduction, and some of it does appear as an afterthought, but it is a very practical accessory to the G90.

[@temporarilyoffline]

Agreed!

[@letmelooktv]

just got a g90 and this cooler. first HF rig :)

[@temporarilyoffline]

Congrats - that's a lot of rig in a small package. If you ever decide to expand, look for the new DE-19 instead of the CE-19. Best solution for this rig and FT-8 and the XPA125B amplifier. Skip the GSOC no matter how tempting it looks.

[@letmelooktv]

@@temporarilyoffline deffo up for some FT8 will have a look at the Xiegu DE-19, thanks.

[@temporarilyoffline]

I used the DE-19 and the XPA125B in this video: kzbin.info/www/bejne/pnjKiZaIaLh3n8k Super Easy. I need to make an FT8 vid on it too. @@letmelooktv

[@mcdonald1743]

How do you like it so far? Is the 20 watts been good enough? Thinking about getting one payday. Only thing I'm worried about is if 20 watts is enough.

[@temporarilyoffline]

I do most of my work at 10w these days, so the 20 on the G90 is a luxury! The g90's built in tuner is also fabulous! It's a great starter rig that will last you until you get the itch for a replacement

[@ShooterReadyStandBy]

I bought the g90 kit from another seller. It included the fan and it works well. I really like that it has the power pole connection.

[@temporarilyoffline]

Can't go wrong with this upgrade!

[@W9HJBill]

I got one for my G90 awhile ago and I can't recommend it enough. Not only does it keep things cool, but the built in Anderson Power Pole input and the folding legs are a very nice touch.

[@temporarilyoffline]

Good Choice!

[@btaylor1948]

I got the cooling stand as part of a G90 package deal and it was a great deal. It does the job. Get it if you can. 73 Bob WB6TIS

[@Dusty_Ham]

The stand is a must after having played with the G90. It's a great add-on. It adds a bit of weight (I was honestly shocked by how hot the entire rig was when I got it!) but definitely not enough to worry about. I love the legs on it as well, so it raises the viewing angle. Great over all for G90 owners.

[@temporarilyoffline]

If you're gonna FT8, I wouldn't be without it

[@RobG-KD9YBZ]

The stand is a must even it the radio never leaves a cushy AC Shack….

[@temporarilyoffline]

Esp now that it has the fan guard!

[@haramanggapuja]

Nice. I’m wondering - for that day when I finally cave & run FT8 on the beast - if I shouldn’t get that & the DE19 at the same time. Your demo has me pretty much convinced, even if all it does is raise the radio off the table better ;-). Thanks for the complete run-thru. 73 de W8IJN

[@temporarilyoffline]

If you are going to do serious FT8, then the digirig or the de-19 should be good. I have both and I need to test them out. But the cooling fan is a must if you want 20w out of it

[@KK6USYHamRadioAdventures]

Awesome TO, I wonder if it would stay any cooler upside-down sense heat goes up? Most thought out amps cool from the top of the amp with a good heat sink.

[@temporarilyoffline]

There is a heat transfer pad right where the finals are supposed to be inside the radio. I haven't taken this radio apart yet, but its on the list!

[@geraldanderson6972]

Hi. Try drilling more ventilation holes in the radio case. There's no good airflow with the few holes I see in the case

[@temporarilyoffline]

That's a good idea. I still need to open this radio up and take a look inside.

[@pastorlarry7470]

I have this fan. My only complaint is it always runs. As soon as I plug it in.

[@temporarilyoffline]

Thanks for watching!

[@DonzLockz]

It works well and it built well including the power connections. I think it's steel but aluminium would be better but I may be wrong. I would buy that if I was portable but it's expensive... if it lived at home, I'd probably do the "low rent" option.😆👍

[@temporarilyoffline]

We call that craftsmanship here. Low rent is offensive 😁

[@DonzLockz]

@@temporarilyoffline haha, okay sorry!😆 Yep, a $5 computer fan and some zip ties or duct tape is "custom craftsmanship"😆👌

[@temporarilyoffline]

Now you're getting it! 😆

[@Tump2010]

I was going to go with the fan base but then I decided to make a radio box around the radio with a fan blowing on it. The G90 is great for FT8 once a fan is on it.

[@temporarilyoffline]

Yes, if you're going to FT8 with this radio, a fan is a MUST.

[@revbikerbigd8664]

Where did ya get the 3 knobs from?link?

[@temporarilyoffline]

Here you go: kzbin.info/www/bejne/iIemkod_f7iridk

[@frankmccormick5766]

Did you put alternate tuning knobs on the G90? Mine are not like yours.

[@temporarilyoffline]

I did, mine broke during shipping: kzbin.info/www/bejne/iIemkod_f7iridk

[@mechadrake]

Does it need the cooling really, does it melt or going to shutoff fot thermal protection at some point? Thise degrees in a manual are for enviroment temperatures, at least they were, at some point when that was explained in manuals. I am still nit sure if to get myself g90 for a go bag, additional fan is unwanted thingy for me, sadly

[@temporarilyoffline]

The fan is only needed for high duty cycle modes like FT8 or high temperature areas. I can't imagine you'd need it for voice modes.

[@michaelwilson6806]

What knobs do you have and where did you get them?

[@temporarilyoffline]

[@temporarilyoffline]

I'm glad they added the fan guard

[@robbannstrom]

So you cooled the radio with ... a fan. Big deal. Try schlepping that up a mountain to do a SOTA activation, with the extra batteries required to power the fan. Here's an idea for SOTA: drop the fan, keep output power to a max 10W or 15W, use a sun-shade and use the radio in a position where the air/breeze can get to it. Works every time.

[@temporarilyoffline]

You'll get zero disagreement from me.

[@southernexposure123]

Cool video. (pun intended) At about 5:18 the audio volume dropped a lot. I'm getting a huge number of videos with volume that's too low for me to hear. Almost everyone who replies to a comment from me about the volume on their videos say they see no problem. I'm only trying to find out if someone else has the same volume drop on this video at about the same amount of video run time. If no one else has a volume drop on this video at about the 5:18 mark it's only happening on my end. All I'm hoping to accomplish by making the volume being low comments on so many videos is to find out how to solve my issue. NOT every video I watch has volume too low to hear. On some videos I can turn the volume down and still comfortable hear the audio. All my computers have the same issue on the same videos. I have really good hearing. Sorry to be a pest. I just want to solve my audio hearing problem. Oh, I also have this same issue on YT movies.

[@temporarilyoffline]

Thanks for the comment, I'll see if anybody else says anything.

[@southernexposure123]

@@temporarilyoffline Thank you very much. It's driving me crazy. And that'll be a short trip.

[@don_n5skt]

Things have come a long way since I melted my power cord into my G90. I have one of the old G90 fans where you have to 3d print the bottom or risk pinching your fingers. Fun stuff.

[@temporarilyoffline]

It's not really yours until you've bled on it, right?

[@don_n5skt]

@@temporarilyoffline And it nearly burns down your house ;)

[@davearmbruster3]

Love the radio and the cooling unit. My only beef is that the cooling unit stays on constantly if it has power even if the radio is off......and mine is a bit noisy. Anyone thought about putting a switch on it? Would be nice not to have to constantly plug/unplug it.

[@temporarilyoffline]

It should have a temperature probe on it, is it not working? If it doesn't have the probe, would be a fun project to add one.

[@davearmbruster3]

@@temporarilyoffline It has the probe, but always seems to run wide open. It's not horrible noisy, but enough to be a nuisance while using the other radios.

[@temporarilyoffline]

@davearmbruster3 probably needs some troubleshooting. I'll have to check mine and see how it's working (or not). A switch would be easy enough to install though.

[@chuckmartin6049]

I think I read somewhere that the fan kicks on at 77° F. I just got the G90, cooling fan and data card in a discounted bundle. I live in Florida and it's always above 77° 😆

[@gailpeterson4012]

a friend bought one and it killed his radio. When I opened it the red and black wires from the power pole plug were reversed and killed the radio with reverse power.

[@temporarilyoffline]

Oh wow! That stinks!

[@surak1841]

So you have a G90 sat on a sealed fan that is in top of a flat surface??? where's the heat supposed to go if you block both sides of the fan?

[@temporarilyoffline]

It has side and rear exits as well.

[@surak1841]

That all? @@temporarilyoffline

[@surak1841]

No wonder it's hot @@temporarilyoffline

[@surak1841]

Not trying to be a dick but the hot air needs to be removed ASAP and as fans work best top to bottom or left to right, your method cuts that route out. Get an old laptop cooler, turn it around and you have an efficient cooler and a better viewing angle, hope this helps, 73

[@temporarilyoffline]

I didn't design the radio with zero cooling built in. I didn't design the fan stand, although it does have legs (which you can see in the thumbnail) to get the airflow that you're demanding of me for some reason. I also demonstrated in the video that the temperature rises and then when I turn on the fan the temperature drops. Looks like you just want to argue instead of look at the actual proof that this works. Have fun. @@surak1841

[@temporarilyoffline]

No problem Frank! Thanks for watching and for the kind words.

[@aldewitt9]

Your fan base is quite large. Pun intended.

[@temporarilyoffline]

Why thank you kind sir

[@mikestone9129]

Does the G90 run hot when only on SSB?

[@temporarilyoffline]

No, not at all. It's just a duty cycle thing and ft8 is pretty hard on radios at full power for 15 seconds and then off for 15 seconds. With SSB, you'll rarely hit full power for more than a second.
