HamGeek Micro PA100 100W 3.5MHz-30MHz QRP HF Power Amplifier Shortwave Radio Linear Power Amplifier

HamGeek Micro PA100 100W 3.5MHz-30MHz QRP HF Power Amplifier Shortwave Radio Linear Power Amplifier

Features:
* HamGeek Micro PA100 100W portable/base shortwave power amplifier
* High-speed automatic TX/RX switching with RF sensing — works even without PTT SEND connection
* Fast automatic LPF (Low Pass Filter) switching — no need for ACC control cable; 5 sets of 5-stage LPFs cover all HAM shortwave communication bands from 80m to 10m
* Power and SWR (Standing Wave Ratio) display with protection — ensures safe operation even with poor antennas, preventing damage
* Wide voltage range with voltage display and protection — convenient for outdoor use with lithium battery power supply
* Temperature display and thermal protection with intelligent dual-fan cooling
* Semi-insert mode — allows flexible operation even without PTT SEND connection
* Supports for ICOM, YAESU, and XIEGU band-switching protocols (ACC control cable required)

Attention:
* Due to cost constraints, the front panel decorative frame is 3D printed, with the default material being PETG-HF filament from Bambu Lab. Please note that 3D printed parts may have visible lines and slight imperfections. If you are particularly concerned about the appearance, please consider carefully before purchasing!

Packaging Details:
* Weight: 1.3kg

Note:
* Battery is not included.

Notice:
* A document detailing the optimization and fix for the HamGeek PA100's interference issue—causing incorrect SWR readings when using a 1/4 wavelength antenna—has been published in the Facebook discussion group. If users raise questions about this issue, the document can be shared with them so they can adjust the voltage themselves.
* It should be emphasized that this is a targeted optimization fix, not a design flaw. This phenomenon only occurs with the rarely used 1/4 wavelength GP antenna and also appears in other types of amplifiers. If users request a return due to this issue, such requests can be refused.
