The DL9SEC Amateur Vector Analyzer

The DL9SEC Amateur Vector Network Analyzer (Retired)

Based upon my DDS-VFO and a simple antenna analyzer by IW3HEV I build this microcontrolled VNA.
The S-parameters S11 and S21 can be measured. The measurement results can be transfered via RS232
or USB (from which the VNA can be powered).

Smaller, better, cooler: edy555's NanoVNA and NanoRFE's NanoVNA v2

The SMD DL2TM programmer

DL2TM-Programmer for ATMEL µCs (SMD version) (Retired)

Based on the original programmer by DL2TM, I developed a SMD version with a few enhancements.
The programmer works for the AT89C2051 and AT89C4051 micros.
