poor SO-239 connectors			Time Owned: more than 12 months.
Bought this swr bridge many...years ago new. not sure about accuracy as I never had it checked but this worked fine for a few years. Its downfall is the SO-239 connectors on the rear, its the type where the centre sprung connector has no insulation between it and the inner casing. This means as the pl 259 is presented it can open the centre connector out of shape if it is not squarely fitted which eventually leads to a slack connection which then causes heating which causes an even slacker connection ..see where I`m going. So if you come across one check the so-239 at the rear for the spring of the connector which should form a nice tight circle.

Solid built meter.			Time Owned: 0 to 3 months.
Well I didn't really need another vswr/rf power meter as I have Diamond SX-200 and SX-600N meters but being abit of a collector I found a mint condition Welz SP15M on Ebay.It's very accurate and now I have the SP -15M for HF and the SP-45M for 2 mtrs and 70cms.If you see one then grab one.☺

Solidly made, accurate VHF/UHF wattmeter			Time Owned: 6 to 12 months.
The SP-45M is a beautifully made analog wattmeter. It's in a solid metal (no, not plastic) case and is sized for base or perhaps mobile use. It is the old fashioned type -- not cross needle -- so you do have to switch between forward and reflected power. Power scales are 100W, 20W, and 3W so these meters are wonderful for most any modern VHF/UHF rig in the shack or the typical handheld. For the VHF/UHF QRPer this is also a fine meter but it's probably a little bigger and heavier than you'd want for mountaintopping. Accuracy seems quite good. Unlike newer products the meter is not backlighted, a minor drawback. The meter is large enough to be easy to read. Frequency coverage is 140 through 470MHz. The Welz SP-45M was sold by Encomm in the U.S. and when they went out of business these meters disappeared from the U.S. market. Welz products continue to be made in Japan and sold overseas. The net result is that most American hams don't know what they are and they can be had very inexpensively on the used market. I like both the construction and appearance of the meter and it works the way you'd expect. Highly recommended.
