Power Genius XL

dlwarnberg

Does anyone have or been using the Power Genius XL yet?  What is the status on the amp?

I see they are able to put on "reserve" but are they even shipping or have they shipped any yet?

Thanks

Nothing specific just getting general feedback on it... looking in the near future about upgrading from my KPA500 / KAT500 combo to something with a little more punch and since I have and have been very pleased with my 6500 thought I'd consider it.

Can you give me some feedback on likes and any dislikes you have experienced with it?

Thanks

This is my first solid state amp so I have nothing else to compare it to.  I had always heard that solid state amps don't like high swr and that tube amps are more forgiving.  I have run the amp with an swr of 3 to 1 and the amp was still happy.  It seems to kick out at 3.3 to 1.  I have to manually tune my 160 meter inverted L which I had forgotten to do before using the amp (which is why I had the 3 to 1 swr).  Once I get the tuner genius, this won't be a problem.  I really like how the amp integrates with SSDR and the Maestro.  Once the amp is tuned on, you get a second set of meters in SSDR and the Maestro.  It's like using a 1500 watt radio.  Totally integrated.  I have run over 1000 watts a couple of times on FT8 just to see how the amp handles 100% duty cycle.  The fans will ramp up to keep the amp cool.  Some bands seem to heat up the amp quicker than other bands but I am told that is normal.  I have also used the amp with my backup rig (Icom 7300) and it works, but not as smooth.  I am using the C-IV interface and it does follow the 7300 frequency, however, when I tune the radio the amp temporarily looses the frequency of the Icom and a relay clicks.  Once I have finished with the tuning knob, the frequency is again displayed on the amp and the relay in the amp clicks again.  I might not have some of the C-IV settings correct. It's like the amp can't keep up with the tuning speed.  Not a big deal but I'm sure I probably have sometime not setup correctly.  This doesn't happen with the flex. 

Some people have complained about the fan noise.  The amp has 3 fan settings (normal, contest, and broadcast).  With the normal setting, the fans are either at idle or very slow RPM until you start transmitting.  With the contest mode, the fans run higher when idle.  On broadcast, the fans run full blast.  I don't find the fan noise objectionable, but I am sure some people will.  I am used to my 2 meter full legal limit amp.  It has a large blower to keep the 8877 tube cool and it is very noisy.  I usually use contest fan mode when running FT8 and normal fan mode when using SSB.  I have not used CW with the amp yet.

Most of my operation is remote from my office.  The amp works great remotely and I can monitor the power output, amp swr and temperature using SSDR and the Maesto with the additional meters. 

At this point, I really don't have anything negative or have any dislikes about the amp.  If I have to come up with a negative (and this is purely opinion) is I wish Flex would have designed the amp with a separate power supply.  My Ten Tec Titan has a separate power supply that I put under the desk.   Having the power supply built into the amp makes the physical size of the amp much larger.  It takes up a lot of desk space but wasn't really a big deal.  I plan to eventually get a tray for my rack and install the amp in my rack with my VHF, UHF amps.

The only issue I have had is a few times the amp meters in SSDR and the Maestro quick working.  The front panel of the amp still works and the PGXL ultility software still shows the meters.  I have heard that there is a beta firmware that fixes this issue.  Once the firmware is available, I'll install it.  To correct this issue, I just have to reboot the 6700 and the amp and then the meters work again.  It has only happened to me a couple of times and is no big deal if you are in your shack since you can still see the amp panel meters.  Would only be an issue running remote.

Thank you sir.. good feedback

If you take the time and ask people that have their PGXL amps now after a long wait, they will tell you the wait was worth it. The PGXL is not your average amp, just look at how it's made and consider the performance. If your already using a Flex radio, nothing can be smoother working together.

That's great to hear Richard!  I hope to take delivery of mine this year.

I wouldn't say these are "currently shipping". I went to place an order for one and got a form to fill out to get on a waiting list. I couldn't even put down a deposit, etc. That doesn't sound like a product that is in regular production.

Which is the reason, when I buy an amp for my 6600, it will be a KPA500 / KAT500. The fact my other radio is a K3 does no harm to that decision. :-)

Loving my KPA-500 :-)
If it gets me this far during a **** solar minimum, with a compromise antenna, it will be FAR more than I need in 5 years when we are in a better part of the cycle.

dlwarnberg

agreed, it's hard for me to justify the cost since I already have the KTA500 / KPA500 combo

Keep watching Mark, 403A said that they are in full production now.

A QRP Version????

I think the enjoyment ROI for an amp drops like a rock past 500 watts.

Eric Gruff

You guys forget that for those of us that contest, 1500 W isn't a "nice to have" for high power class entries. I agree that 1500 W for FT8 (except on the 160 and 6 Meter bands) is excessive, but many of us need/use the full legal limit for CW and SSB.

I'd also rather have an amp capable of 1500 W that I can turn down to 500 W as needed than a 500 W amp that's running at full capacity. I'm a lot less likely to destroy the former than the latter. This is what's left of my SPE 1.3K-FA solid-state amp - it was running about 750 W on 80 M when this occurred with no warning. It's the third time the amp has immolated itself.

Same here !!! Would rather throttle down or back off an Amplifier for improved Reliability 73 Mike

Thanks Guys appreciate the update info

I think so too, The current PG XL is more amp then many of us need. Something smaller, less power would be a nice nitch.

Ted VE3TRQ

And with an option of a built-in tuner :-)

I've never found the need to run more than 300 watts using a small vertical. That little power has gotten me 9BDXCC (10 if you count 60), 9BWAS (10 if you count 60), 16 different WAS band/mode combinations, Triple Play, 5BWAZ, SSB WAZ, Mixed WAZ, almost 1800 band points etc.

I even got Navassa Island when it was #1 most wanted on 6 bands busting though the largest pileups I've ever seen. You can do a lot with a little power

If everyone lowered their power a little bit the bands would be so much cleaner and easier to use for the rest of us. Try it. You might be pleasantly surprised
