AD-5526 Digital Multimeter

The AD-5526 is an ancient multimeter from A&D but for $10 one can’t complain. Has all the basic features one would expect from a multimeter and at 5.2 cm X 9.5 cm X 2.6 cm, it’s quite compact. Uses a LRV08 12V alkaline battery – not a common battery in the USA.

Maldol MH-510 Antenna

The Yaesu VX-8R FM transceiver comes with a stock antenna (YHA-65) consisting of the “Base Antenna” - recommended for operation above 50 MHz - and the “Extender Element” for frequencies below 50 MHz. With this antenna, I was receiving signals from only a couple of repeaters, and that too restricted to certain parts of my house. The N6NFI repeater (Frequency 145.230 MHz, Shift –600 KHz, PL 100 Hz) was the one with the best signal, and I could hear some nets like the SCARES weekly net , all on the 2m VHF band . I also had very little success transmitting indoors with the stock antenna. Outdoors, the transceiver worked pretty well with the stock antenna. Having seen good reviews for the Maldol MH-510 antenna at, I decided to give that a shot. The antenna is for 6m VHF, 2m VHF and 70cm UHF . It is 20.75” tall and is thin and flexible. Gain is advertised as 0/0/.32 dBi and the MH-510 can handle up to 10 watts. The antenna terminates to an SMA and fits directly with the VX-8R.
