Visit to NI6BB, USS Iowa, San Pedro, California

The big guns of the USS Iowa.

As many regular readers of this blog may know, I try to visit as many special amateur radio stations as I can when working overseas.

This week I am in Long Beach, California again for a conference and it was an ideal opportunity to visit the famous battleship USS Iowa in nearby San Pedro, which has an amateur radio station with the callsign NI6BB.

USS Iowa (BB-61) is a floating maritime museum that is well worth the visit. It has a rich history that spreads from World War Two, through the Korean conflict in the 50s, and the cold war before it finally became a museum in 2012.

Its main battery consisted of nine 16 in (406 mm) Mark 7 guns, which could fire 2,700 lb (1,200 kg) armour-piercing shells 23 miles (37 km). On the tour you find out how they used to load the guns with six 110lb silk sacks filled with powder, which when ignited with a single cartridge would rapidly burn in one third of a second, firing the 1,900 lb (862 kg) shell out at 2,690 feet per second (820 m/s).

complete with plastic owl!

The other statistics are staggering (including 19.7-inch armour plating), but I’ll leave you to Google them.

Anyway, back to the radio, the radio room on the Iowa is well equipped with a Kenwood radio for HF.

On the bow of Iowa is the discone-cage antenna. Fed at the top it is a discone providing coverage from approximately 10 to 30 MHz with a VSWR below 3:1. The antenna has a plastic owl on it to stop pigeons resting - but they ignore it apparently!

Ron Frank N3HI let me operate some 20m SSB from the ship, as I have G0KYA/AB8ZV UK full and US Extra Class licences, and I worked a few stations including Washington State and Ohio. One was a “nearly” as I couldn’t quite get his full call before he faded away, which was a shame. HF conditions weren’t brilliant.

There were one or two loud stations on CW, which they often work, and Ron says they tend to operate a lot of digital too, including FT8.

Anyway, my thanks to Ron for letting me play for an hour and giving me some detailed history of the USS Iowa. If you are ever in the Long Beach/San Pedro area go and visit. It is truly fantastic.

My thanks to Ron Frank, N3HI.

I also revisited W6RO, "The Queen Mary", in Long Beach, California where I am staying. I operated from there in 2012 and they always welcome visiting radio amateurs. We had a long chat about UK and US amateur radio.

Elecraft K1 discontinued

Elecraft has announced that it has discontinued the K1 transceiver. I'm not surprised as this had been predicted some time back.

Component availability had been an issue, and technology has moved on.

Luckily, a local ham managed to get one of the last K1s after reading about them - and seeing this blog.

I'd like to thank Elecraft for producing a great little radio and for supporting QRP. There's always the KX2 and KX3!
