I'm pondering purchase of a (probably used) AL-82. My current amplifier is an SB-220, which I use like an active antenna tuner, and which delivers 950-1300 watts 10-80 meters.. Where my K3 will fold

ORIGINAL MESSAGE: (may be snipped) REPLY: Yes on CW, but don't run full power on RTTY. Mine smoked the tank coil twice, once on 80 and once on 160. I asked the designer, W8JI, about it and his reply

The AL-82 uses a pair of 3-500Z's and 1500W is a strain on them if long term reliability is wanted. Carl KM1H ORIGINAL MESSAGE: (may be snipped) Is the power supply adequate for 1500W CW in contest s

Hi, Having owned an SB-220, and an AL-82, I would take the 82 any day... Here is why: Good Points: 1. Solid as a rock 2. Full output on all bands, RTTY contesting 3. Will do 10 Meters 4. Easy to tune

ORIGINAL MESSAGE: (may be snipped) REPLY: A lot of amps have this problem. How about lowering the fan speed with a resistor then shorting it out when you go to transmit. A 555 timer IC could be used

Since the AL-82 uses the same PS and RF section as the AL-1200, and AL-1500 which are known to have failed for others in a RTTY contest at a full 1500W I fail to see how the AL-82 is any different. P

Hi Carl, If in fact the Power Supply is the same as other failed Power Supplies, then you are correct. Maybe it is the de-rating that keeps things under control? Any thoughts there? Nice to know the

Carl, Thank you for the information, I run the amp at 1000 W for any 100% duty cycle mode, and 1500 for CW/SSB, if in a contest. If normal operation, I run the amp at 500 W for 100% duty cycle modes,

And you can also easily run a 400W carrier as an AM linear, a mode that is getting quite popular again. Carl KM1H -- Original Message -- From: "David Cole" <dave@nk7z.net> To: "Carl" <km1h@jeremy.mv.

Yes if you reached 100% modulation then your PEP = 4x your carrier, the same for your radio on AM you should limit to 25w if you got a 100w radio. Without measuring tool you can increase your mic gai
