Due to an illness and subsequent surgery, we will be closed until early December. We will open when you see the PayPal buttons appear. Technical support via email is the only service available until then.
Your PayPal receipt is your confirmation that we have received your order. Stock availability and shipping volume can delay shipping.
The QRPGuys simple RF Probe is a proven, useful, and simple diagnostic tool every amateur bench should have. You can trace rf voltages up to 70v, well through 30MHz. Our low cost version is compact, simple to build, and has a female bnc connector to attach to your inexpensive 11 megohm DVM or oscilloscope for measurements.
