A solid easy-to-use performer.  Time owned: 0 to 3 months
I have recently had the opportunity to spend some quality time with the LA-1K HF LDMOS amplifier, one of the newest solid-state amplifiers for HF (1.8 to 54 MHz) from Palstar. Their products are built in the USA and are known for their quality, support and exception performance. My Icom 7610 connects to the LA-1K with a single RF jumper. The LA-1K then connects to the Palstar HF-Auto tuner with another single RF jumper. I have three antennas attached to the HF-Auto tuner allowing flexible operation across the HF bands. The 7610 allows me to switch bands very easily, just one key-press and I'm good to go. I then change modes to RTTY and tap the PTT... This is when the magic happens. Within seconds, both the HF-Auto tuner and the LA-1K have detected the TX frequency and automatically adjusted for the correct antenna, tuned for lowest SWR and switched bands ready for 1Kw transmit. All this happens without special proprietary cables between the units. Both the HF-Auto tuner and the LA-1K sense the frequency upon transmit each and every time and make automatic adjustments, compatible with any HF radios without the need for programming or interface cables. The touch screen on the LA-1K is about the same size as the IC-7300's touch screen and is very clean and intuitive for use. Having the ability to make menu settings or placing the amp from operate mode to stand by with just a tap of the screen is very nice, completely silent and no wear and tear from mechanical buttons, knobs or switches. I usually drive the LA-1K with about 40 watts from the 7610 which produces just under a kilowatt of ultra clean RF to the selected antenna. I previously avoided pile-ups because it was too difficult to get through to the station calling CQ. Now, I look forward to the challenge. Armed with the LA-1K it usually only takes a call or two and they come right back to me, almost always commenting that my signal is strong with clear audio. It is a pleasure working with this high-quality amplifier and it is evident to just about everyone I talk to how clean and strong my signal is, regardless of the mode or band I am operating on. I can't say enough good things about the new Palstar 1Kw solid state amplifier. Itís as easy to use as my 12v power supply, just turn it on and off with the single switch on the front and it does the rest by itself. It is a solid piece of equipment and a worthy investment. Hope to catch you on the air, 73 KD4POK
