Back in July, I ordered the NanoVNA, a credit-card sized network analyzer: https://www.aliexpress.com/item/33045381877.html?spm=a2g0s.9042322.214.171.124c14c4dalCaKeke Under $50 with free shipping, works well as advertised. Today I learned about, and ordered, a larger version that is easier on the eyes for older folks with visual acuity disabilities. This one is just over $100. No longer will I be using my MFJ-269! https://www.aliexpress.com/item/100...2g1y.12024536.productList_408693596.subject_0 The code is open source, but it is still somewhat surprising that these devices can be produced and shipped for such a small sum. The time saved compared to earlier devices in immeasurable! By the way, it is shipped with cables, shorting connector, open connector, 50 ohm load connector (for calibration) as well as a USB C cable. This can be used for charging the lithium battery, or connecting to a computer and driving it on the big screen. Worth a look.
