Have the Power Genius XL Tuner Dimensions been finalized? I am going to have a cabinet maker make a cabinet to house my PG XL Amp, Beko HLV1000LDP 2 meter amp, FLEX-6700, LP-500 Station Monitor & FLEX amp tuner. Are the dimensions of the tuner finalized so I can go ahead with design/build?

No, not yet, but will be reviewed next month.  Please feel free to offer suggestions or requirements.

I hope the tuner will be out of the antenna circuit on Receive. The reason is, when monitoring many bands and the tuner is matching a low frequency band the tuner presents a big loss on the higher bands. IE. if a 6700 is monitoring 6-8 bands of FT8 and the tuner matches 80 or 160M bands the other bands will drop dead. this happens on ANT2 on the 6700 now. Ant1 does not have the tuner in line with the antenna on receive.[not widely known].

Not related to dimensions but I sure hope the tuner is cable of tuning more than 3-1 swr.  My MFJ 998 auto tuner is capable of 32-1 swr and 1500 watts,

Reg, please post a few photos when your project is done.   I have similar equipment, and will love to see how your cabinet turns out.

Last I saw the claimed matching range of Tuner Genius was minimum 3:1. Keep in mind that just because a tuner may capable of matching a higher SWR load does not mean that it will match any load showing that SWR.  It depends on the characteristics of the load:  band, high (>50 ohm) or low (< 50 ohm) Z, resistive or highly reactive load, etc.  Most tuner specs are based on resistive loads, so don’t mean a lot in the real world. 

The MFJ 998 specs show a matching range of up to 32:1 SWR for loads over 50 ohms but only up to 4:1 SWR for loads under 50 ohms.  Note the “up to”.  Throw in significant reactance and those matching ranges will decrease.  For example, my LDG 1000 has a claimed 10:1 matching range, but my 160M dipole has a freq. range where the LDG can’t find a match at even a 3:1 SWR.

To me the big advantage of the Flex tuner is integration with the Flex amp and radios via LAN.  I don’t expect a wide matching range at high power with a switched inductor/capacitor tuner like this.

Understood.  That being said, I haven't found an antenna yet that the MFJ couldn't tune.  Currently the only antenna that I need a tuner on is a 160 meter inverted L.   The antenna is cut for the low end of the band but if I get up towards the top end of the band the SWR goes up over 4-1.  The MFJ tuner just takes a second or two to tune on the top part of the band.  Really looking forward to seeing some specs on the new tuner although I am still waiting for the PGXL amp!

Burch, I think you’ll be happy with the amp.  The LAN-based control (including PTT) and Flex integration is fantastic.  I just got mine back from the 6M fix, loaded with the latest firmware, and noticed some nice improvements.  I’m using it with a manual tuner for now (my LDG is used with my Icom), and can’t wait for the tuner.

I'm really looking forward to getting the amp.  The tuner will just be icing on the cake.  20 months and counting.

Howard, what were the improvements?

Need an update from Gerald on the PGXL.

I just want an update on when I will get my amp.  Purchased at Hamcation coming on 2 years now on the first day Friday!  Would like an update soon Gerald!  Not holding my breath on the tuner either.

The wait is brutal but it’s well worth it. It really is an outstanding amplifier. Much better if you can put it across the room from you cause it’s on the loud side compared to alpha or acom. For someone like me that listens much more than operates it’s good to change your operating style so you flip it from stand by to operate when you wish to transmit and back again if you won’t be transmitting for another 20 min or hour (or 9 days). It goes from standby to operate in a second, really cool! Hopefully they release more updates that give us the option to make the fan ramp up from a true 0.

Bill, a couple improvements:  When I first got the amp I held my dBA meter about 18” in front of the amp while the fan speed was at the low setting.  The reading was 56 dBA (the sound level in the room with everything turned off was 37 dBA).  When the amp was returned from the 6M fix it was updated with the new firmware.  I rechecked the noise from the fans, again at the low setting.  The reading this time was 50 dBA.  Not a big change but going in the right direction. 

Also, now you can set the keying delay to 10 ms, as opposed to the previous 20 ms.

With the previous firmware the panel backlighting (which indicates the state of the amp) was dim, and the control to adjust the brightness was inoperative.  In the new version it works and the backlighting can be turned up to where it is quite visible in a brightly lit room.  

I agree with Matt, it's an outstanding amp.  Currently I have it in the back of the bottom shelf next to my operating position, which helps considerably in abating the noise.  Hope you don't have to wait much longer!
