Power Genius XL Update from Flex Insider 10/5/2018
Note at the bottom of this update:
"The sales team will be in touch with each of you over the coming weeks to finalize your orders. We plan to provide a more detailed schedule for when you can expect to receive your amplifier in next week’s update."Dear Power Genius XL customers,
I am pleased to report that all amplifiers upgraded this week are working extremely well and that we are on track to resume production shipments by November. We are now receiving a steady flow of modules from the factory and the retrofit/burn in process is progressing smoothly.
Last week’s update focused on our testing process, which results in optimal reliability and strong performance, even under contesting conditions. This week, I’d like to share a recent contest example that illustrates the quality and capability of this outstanding product.
In what may be a first in amateur radio contesting, K9CT’s (Craig Thompson’s) team ran Power Genius XL in a Multi-2 RTTY configuration where two operators shared a single amplifier thereby cutting the cost of RF power in half.
Steve, AI9T, on the left is calling CQ on a FLEX-6600 while Mike, ND9G, on the right is searching for multipliers on a FLEX-6500 - each using Maestro controllers. Both radios are connected to a single Power Genius XL, seen just above Steve’s head, running 1,500W output on RTTY continuously for 48 hours. A second team ran an identical setup on another band.
The team placed #1 in the USA for M/2 HP with over 3,000 QSOs from the middle of the country. They even outpaced several teams in Europe in the same category.
Even with the powerful performance capacity built into the amplifiers, in normal legal limit SSB mode, the fans run at nominal speed. Only when using high duty cycles like RTTY and FT8, do the fans ramp up slowly to a moderate volume to keep the LDMOS transistors cool.
I would recommend this amplifier to any serious ham radio station. It is lightweight and can be mounted anywhere in the shack. No need to be in your face as there are no knobs to adjust and the same indicator that is on the amplifier can be on your computer screen. You can toggle Standby to Operate anywhere you have the application running. If you have a FlexRadio setup, everything can be operated remotely, including the amplifier. Very simple, but powerful.
Several hams had asked if the amplifier was suitable for 6m DXing. I have tested the amplifier using JT65, MSK144 and FT8. JT65 has the longest duty cycle and the amplifier held at 1500 watts. The PGXL will work for EME for long periods of time. I have no reservations recommending using the amplifier for 6m DXing.
For those of you waiting patiently, we thank you. The sales team will be in touch with each of you over the coming weeks to finalize your orders. We plan to provide a more detailed schedule for when you can expect to receive your amplifier in next week’s update.
Gerald, K5SDR & and Ranko, 4O3A
