VK Amplifiers-1KW HF/6M LDMOS Amplifier Kit
Why VK Amplifiers Are the Secret Weapon Every QRP Ham Radio Nerd Needs (Spoiler: I Want One!)
Hey Ham friends! Let’s talk about something that’s been living rent-free in my brain lately: VK Amplifiers. Now, full disclosure—I don’t own one (yet!). But after falling down a rabbit hole of forum threads, spec sheets, and YouTube videos, I’m convinced these amps are good value. Let’s talk about why!
I recently bought a Hermes Lite 2 and saw one built into a VK Amplifier. That's what initially caught my interest.
The VK Hype: What Makes These Amps So Special?
Look, I’ve seen my fair share of Ham gear. But while looking for an amplifier for my Hermes Lite 2, VK Amplifiers kept popping up in conversations. Here’s what stood out in my deep dive:
1. Input Power: 3-5w for full output!
2. QRO and They’re Built Like Tanks (But Cooler-Looking)
3. They Play Nice With Your Gear
Ever tried pairing an amp with a finicky transceiver? Spoiler: It’s not fun. But reviewers swear VK amps are easy to integrate, minimal drama, and packed with safeguards against SWR tantrums.
4. Real Talk: What Are Users Saying?
I stalked Reddit, Ham forums, and even a few obscure Discord channels. Here are some comments:
- “My VK saved our butts during a wildfire comms blackout. Zero dropouts.” – Emergency responder in California
- “Finally, an amp that doesn’t sound like a jet engine!” – Contester who values sanity (and sleep)
- "The best LDMOS amplifiers on the market. Definitely would not go back to a valve amp. Acom are old technology. The VK3AMP is brilliant! - Facebook comment
Should You Consider a VK Amplifier?
If you’re nodding along to any of these, maybe it’s time:
- You’re tired of not breaking through the pileups.
- You have a QRP rig and want QRO.
- You don't want to use a smaller 100w amp connected to a 1Kw amp.
- Building an amp can be a fun project.
K0PIR Tip: Don’t skip the research!
The Verdict (From a Non-Owner Who’s Jealous)
Let’s be real: VK Amplifiers aren’t cheap, but $2,200 is a pretty good price for this solid state amp kit. (They can be ordered as complete) But from everything I’ve read, they’re the “buy once” upgrade Ham operators want. Clean signals, rugged builds, and a cult following that’s hard to ignore.
In addition to incorporating my Hermes Lite 2 into the amplifier case, I could also install a Raspberry Pi 4 to make a complete station. Just add a monitor, keyboard and mouse
If my wallet allowed it, I’d already own one. Until then, I’ll just keep making videos until I can afford one. Please subscribe to my YouTube channel.

Does this sound like a fun project? What have you heard about these amps and are they difficult to assemble or should I pay the extra $$$ and order it assembled? My original plan is to build one and add the Hermes Lite 2 inside of it. More coming on the Hermes Lite 2.
