I got mine in the summer after waiting in a pre-order queue. It's been on a couple of expeditions with me now, and it brings a massive benefit to the IC705 experience. QRP can be fun, but it's a pain when the band isn't in the best of conditions. The amp won't fix a closed band, but it will get you out of the weeds. Also, if you get cold when you're camping, chuck the amp in your sleeping bag and start making FT8 contacts. You'll soon warm up. :)
Best comment of the day 👍
The DIY599 is the perfect pairing with almost any low power radio - I have used it with my KX2 KX3 X6100 IC705 and the TX500 - it is truly plug and play
Thanks Julian!
A couple comments
I love the PA-500 and use it with the 705 and TX-500.
The LED lights are important and hard to see if you mount the PA behind the radio
The 10m function on the FCC/USA version is a little wonky because of the requirement to not amplify the 11m band - there is a limited work-around.
Oliver and Ed are both approachable and super helpful when questions arise
In hot climates and direct sun - the amp can go into self preservation bypass mode quickly, particularly when using FT8. this can be managed by limiting output power to 40w in my experience
The ic-705 max power setting is nice, but you still need to check it and the power level in the multifunction button - to prevent mistakes
For CW, I use the VOX delay setting on the radio - which seem more effective than those on the amp - to prevent the amp from relay clicking
All told - it's a kick ass package, very happy I got it
I saved many times and money following your advice for portables operations and prepping communication.
Thanks for your job. 73
Really needed to hear something like this today. Thanks for watching and your kindness is greatly appreciated.

Oliver has created an excellent product in the PA500. The demand is large and the supply is limited. I think your arguments are very well founded and I follow you closely. I hope to achieve exactly this setup. There are situations that require more than QRP. I am working on having this configuration. Learned a lot from your arctic expedition and please to be Patreon supporter.
Please know you and Oliver are much appreciated!👍
Julian, this is exactly what I asked for. Excellent video thank you for making the video. Your the best! 73!!
I'm glad you found it helpful. Apologies for it taking so long. You know I get stuck in the details:-)

@Off-Grid Ham Radio OH8STN The details matter and we love your explanations! Thank you sir.
Thanks for the video. I just received my PA500 and TX500 combo package. But I also own a 705 and your video helps me both ways. I didn’t know about the HF Vox feature which makes it so much easier.

You are very welcome. Thanks for watching, commenting and for telling us about your new setup. Merry Christmas and 73.
Julian oh8stn
Perfect. I shall be setting my stuff up when I get to Ireland on Wednesday.
Whats going on in Ireland? Can we sked?
I just noticed you have the cage on the 705 mounted upside down to utilize the handle as an angled base. That’s a clever solution. I’m going to try it with my rig. I enjoy your channel and appreciate your efforts.
Thanks for the kindness and for watching. I just moved the handle to underneath the 705. This way you can be used as a tilt meganism. Peovi sales the extra handles now 👍

Very interesting one more time ! Thank you for the job.
Excellent. Good info. Thanks.
Can’t wait to get my amp:)
It's definitely worth waiting for. Thanks for watching and commenting. Very much appreciated.
I really like this channel… radio is like the OG livestream….😂
Thanks. Like a home defence Blitz, we need tools to help us adapt to the changing world.
Great video 👍🏾.
Please do a setup guide with the PA 500 and the LAB599 TX-500. Excellent setup guide using the IC 705.
Noticed that you recently got an Extended PA 500. Might want to clue us in on that one if you have one.
Mahalo
Yes I just got the Expedition model. I'm collecting the clips and then we'll sell it on to some lucky person in the world. Tx500 setup guide for the PA500 is already incoming.
Thanks for watching, the feedback, and the kindness.

Very nice video
Thank you for the info. I am happy with IC705. My concern is the availability of the PA500, hard to get and cost; this make me to choose / find other option. My setup at the end is using IC705 and FT891 if I need more power for portable/mobile operation, a half square antenna 40m with 2x 10m spider beam (shorten to 8.5m), 49:1 high efficiency UNUN for both device, connect to a coax switch, only ‘turn on” one device at the time, one computer, a generic ATU for backup antenna setup, power/battery usage is about the same and I had a spare HF radio for redundancy.
The ft891 is an awesome radio but it's terrible with efficiency. The 705 even with the PA500, is far more efficient in transmit and receive. Anyway, I like the antenna idea. Naturally we should always start off with an efficient antenna. I believe this is almost the first thing I said in the video. The only reason I sold my FT891 was the current consumption. Sometimes I miss it, until I think about how hungry it was.
When I think about the g90. I wonder why it wasn't possible to put 20 watts inside the 705. That would have been absolutely amazing!
Thanks for watching, commenting and for the kindness. Greatly appreciated.

Great job Marine, As per usual! Semper Fi De WV1Q
Semper fi brother 🙏
I've been on the list for nearly a year, but got a Hardrock-50 kit recently, partly in anticipation of their coming 100w upgrade. I have no idea now whether I'll purchase or pass on the PA500 when I get contacted. There is a two is one, one is none quality to the idea of having one amp for home and another for field, but there is also the quality of leaving more money in the bank 😄
Perhaps the Hard Rock 50 is better suited to a desktop than in the field. It's weight was the deciding factor. I wish these were more readily available though. Thanks for watching.

There are times between the solar cycle peaks when the MUF is below the 80m band. An amp that can do 160m would be useful during those times.
Like always, love the video.
What field expedient nvis antenna do you use when reliable contacts are needed? Using js8call, does that effect your selection?
Excellent question! For NVIS, off center fed dipoles cut for 80/40/20 (JS8Call) or 60/30, ... (Winlink). If I'm unsure about the requirement, a terminated dipole.
Thanks for watching and commenting. It's very much appreciated.

I've been on the waiting list to get a PA 500 for quite some time from the QRP store. I see they're currently available in Europe on pile up DX's website. Unfortunately I can't order from them and get one shipped to the US. I need to wait for the QRP store to get one in stock. :-(
Many thanks for the very helpful support..stay tuned DH7TB
I contacted the QRP store around Nov. 21, 2022 concerning the availability of the PA 500. I was told
they were working on orders from Aug. of 2021 I've been added to the waiting list. It's frustrating
when equipment is unavailable, or discontinued.
Definitely frustrating. Remember this isn't a mass produced product. It's so special because it's well designed and uses quality components. Hang in there more of them are being produced now than they were previously.
Bonjour,
Excellent, je ne sais pas où trouver cette amplificateur en france
Merci pour la présentation
I got mine in a week. Canada has different inport regs than the US. Perhaps you guys that are still waiting have friends up in CanuckLand that could help out.
Excellent point. Yeah here in EU we get them pretty quickly as well. Hey thanks for watching, thanks for the suggestion and wishing you lots of good times with your PA500.

Really good video Julian. I'm looking to expand my IC705 as I only use it alone with an Alex Loop, although just the other day I managed Australia on my loop, on 10w on FT8. Do you really think the PA500 is a worthy investment? I know I cant run it through the loop as I think that's only 20w max. Thanks 73
Will the amp work on 60m both tx and tune functions ?
It will but not by default. You have to update the settings on the amp if you'd like 60 m. It's not difficult, you just need the USB cable.
will i destroy the amp if I accidentally over drive it with 10 watts? Hope to get mine in January been waiting over a year.
You could. It usually depends on how long you tx into the amp at at the tx power.
Hi folks, I bought the pa 500 but I’m having problems while using it with my IC 705 and my pac 12 antenna. After using the amp on the 705 for more than a few minutes my modulation starts to degrade to the point where it’s unreadable. Has anyone else had to use ferrites on the co-ax or mic leads or is there any other solution to stop this happening?
Thanks!
I’d. Love to see a comparison of power draws between the old 706mkii, the 7000 and the newer 705 in receive and at 10 watts out
Thanks for the super thanks and for the question.I can do the 705 part of this easily. We'll need to rely on published documentation for the others.
73
Julian oh8stn
@@OH8STNthanks . Thinking about it I can likely measure the power draw in receive mode of a 7000 in the next few weeks. I’ll post them here
Excellent, please tag me when you comment. @oh8stn 👍
@@OH8STN- some prelim readings all from freshly charged bioenno battery with radio on at low volume tuned to background noise :
Yaesu FT-891: 1.02 amps
Icom 7000: 1.28 amps
Ten-Tec argonaut VI: 0.58 amps
Icom 705: 0.33 amps
It's better to test using a power supply. The current consumption chanjust as a battery's voltage increases or decreases. So use a power supply, and list 1.x amps @ 13.5 volts for example. This tells the entire story.
Will yaesu bring a competitor for the IC 705?
That's a great question. Honestly, nobody knows. Yaesu seems to be focused on contest radios. It would be nice to see them throw their hat in the ring.
Julian, I'm not a Microsoft fan! What do you recommend on the Linux software side? Or Android based tablet?
I'm not a Microsoft guy either but software ham radio Community is abysmal. I would go with your favorite flavor of Linux on your favorite brand of laptop. For modes like js8, packet, aprs, Linux is fine. For winlink, there is Pat winlink. Pat works but you lose a lot of the features from the windows side. It's kind of the bare minimum. Other than winlink, I would say Linux is okay.
Can't even find pa 500 anywhere
typically input is the max of 5 watts on input to power amp
That's probably true on a cheap Chinese made amp. With higher efficiency, lower drive can give us the same output power.
Thanks for watching.
For me qrp make non sense. If you need to make a contact in an emergancy case with 10 watt it could end very bad. For me that is, like driving a truck with 40hp. The ic705 with the pa for HF, a Tuner for HF, an amp for VHF, a Tuner for VHF you have 4 times the mony, 3 times the space and 2 times the wight of a 991a. Please dont understand me. This is only my Opinion. I Love your Channel and your contand. You are a really Great ham Operator 73 Horst
QRP is not required by law. If you don't like it or can't do it, use the 991A.
The real story.
991A runs at 2-3 amps on RX, 20-23 amps TX with 100 watts. Even at 5 watts, the 991A still uses 9 amps on TX. So add the weight of the massive battery for the 991A as part of your system.
If yout cabin burns, vehcle is broken down, ... how far can you carry the 991A and the battery to power it? How long will the battery power such a current hungry radio? For me, usually the 705 or TX500 is enough.
This makes absolut sense to me sir
This is such an awesome setup - but forget paying $3500 for an amp - that's just insane. I want an amp for the 705 but the cheapest best solution is the Elecraft. Yes there are cheaper options out there but the Elecraft is quality. This is also quality - but that price for these are just not reasonable.
They don't cost $3,500.
The Elecraft is a nice amp, but it's not as energy efficient, doesn't have us low current consumption, and it's incredibly heavy. The Elecraft is meant for the desktop. The standard PA500 comes in around 900 bucks.
When i am in my Hunting Cabin where there is no cell service i have a Windows Laptop for Winlink althouhg i am a mac guy my 991a from Yaesu Full Open on transmit and my chamelion wire antennas. If i hurt myself i dont want to bleed out with qrp and a solution with 20 wires and connectors every one mc. I know there a better radios out there. The reciver in the Icom rig is better. But i have a one Box Solution. Strait and simple.
and a large battery pack yo power the 991A. 99% of the time I operate QRP winlink. If you know what you're doing, you can usually get it done. An inexperienced operator will certainly have problems with lower power.
@@OH8STN i dont want to criric you!! You are 100% right!! It is only the way i do it! You Need More expiriance for qrp
If *you* are the one that's bleeding out, making qrp contacts should probably not be in your priority list...
In the military they told me, take the right tool, do it strait, simple and reliable. I put my lifepo4 in an Isolation bag. Had troubles in the past with the batteries in 20 below Zero c. I think i have good possibilities with the 991a Open transmit. I can to calls to the mountain rescue. Home to my wife with vhf. And Winlink and calls to other hams on hf. 73 Horst
Ouch! Nobody has is for sale and only saw it on a reseller from Europe for $1200!!!! No way, the amp can’t be more expensive than the 705. Well, I went with the PA50 and have a lot of money leftover to spare
I don't like the PA500 price, but wouldn't compare the PA50 to it. PA50 is less expensive, but also lacks the tuner and heat protection.
If the PA50 works for you, be happy 👍
@@OH8STN I agree with you that can’t be compared because is 2 devices in one like the Xiegu amp which cost around $600 but is not as compact as that PA500. Anyways with those $1,200+ I can get the PA50, one of the nice tiny tuners and still have money leftover for other stuff. Sometimes I don’t understand how people price the stuff. Thanks for the video my friend.
Yeah the pricing is based on demand. This is a very frustrating truth. The PA50 and one of N9SAB OCF dipoles wouldn't need a tuner 👍
Don't buy a QRP transceiver if 10 watts is not enough for you. There are plenty of great mobile high-power radios on the market. This is QRP radio.
Complete Nonsense!
QRP rigs are attractive because of their low current consumption and small form factor, not the output power! High power rigs consume vastly more current on RX & TX than a QRP rig and efficient amp combo.
@@OH8STN We can argue for hours about this, right? How many amps does your amplifier consume while on standby?
@makskk6spm275 80ma on RX, 10-12 amps at 80 watts or 100 watts for the expedition version!
Manufacturers don't care about efficiency in 100-watt radios. I sold my FT-891 for exactly that reason. Also passed on the 857, IC-7300, ... because of poor efficiency. When your radio pulls more than an amp in standby, the size of the battery reserve storage must be increased. If you're running off-grid renewable, input current requirements also increase. The only way to get an efficient low current radio with QRO output fitting in a small pack is a QRP rig/amp combo.
This is an old, well-covered, and extremely annoying topic. Not because of your comment, it's because manufacturers don't care. The manufacturer who develops an updated FT-897 style 100-watt radio with LiFePO4 internal battery, running less than 100ma RX and 10 amps on TX will be an innovator.
Yaesu already did it in the Vertex HF radios. Sadly, they sold that division Motorola.
@@OH8STN 0.08A in RX on 100W amplifier? what amplifier you are using? just wondering.
