1kW Larcan 144MHz amplifier. 25W drive produces 1kW output. $1050US total shipped Canada/USA. I've converted about 40 of these, and unlikely there will be many more. 1kW Larcan 50MHz amplifier. 6.5W drive produces 1kW output. $800US total shipped Canada/USA. Both amplifiers picked up from...

I'm planning to install a HF dipole fed with 450 ohm ladder line. At the center point I have a Ladder-Loc center insulator by WA1FFL. It looks very good, but I question how much stress it will handle. The copperweld wire will be held in a Pyrex center insulator and the Ladder-Loc will be a...

Thought question... Not meant to warp anyone worse than they already are. I'm planning to use a crossed yagi antenna on 2-meters. Instead of one set of elements being for vertical and the other for horizontal I want to mount the antenna in an X configuration with each driven element at +/-...

Harris Platinum SSPA 6M and 4M dual band amplifier. Approximately 10w drive is needed. On 6 meters it will produce about 1400W output. Add RF connectors, a PSU (about $40 on ebay), cooling, and T/R relays. EME QRO on 50 MHz. See here for better info and pics. Harris Platinum I Channel...

Very limited quantity of Larcan 6-transistor 1.5kW amplifier modules. (upper picture) No mods needed for use at 222MHz. Gain about 16dB, 40 watts drive needed for full power. DC input power connector and schematic diagrams included. I've shipped several in a manner as shown below with...

I have several Larcan 1kW lo/lo amplifier modules for use on either 6-meters or modify for 2-meters. Lots of info online. I also have 1kW high band VHF modules. These will work well at the 220MHz band. I'm not confidant of their operation at 2-meters and have not seen credible...

I still have a few of these left. 1kW+ on 6 meters or convert to 2 meters. 6M / 2M kilowatt amplifiers
