New Kenwood TS-590 Release Specifications


Kenwood_ts-590

The new Kenwood TS-590 that created a buzz at Dayton this year is finally being released worldwide this October. Kenwood Japan has released the final specifications. It looks like it’s going to be a superb receiver but the pricing looks to be well over 2K USD. Kenwood’s Japan site lists it at 228,900.00 JPY=2,679.41 USD. No doubt this is due to the fluctuating value of the YEN these past few months.

You can read all about it at these links at Kenwood Japan

California Dreamin’

June and July were busy. Two trips to California and I’ve only been back less than a week from the last one. I had a few days of work and took a few days to just take it easy and see some of the coastline of California. One afternoon was spent on the Pacific Coast Highway north of Los Angeles. Then it was off to San Diego, a beautiful coastal city on the border of southern California and Mexico.

San Diego is home to the Pacific Fleet and there was no shortage of things to see in the harbour. Below is the USS Nimitz, a nuclear powered aircraft carrier anchored at the San Diego Naval Base. The USS Carl Vinson was anchored alongside.

US Navy armed patrol ships continuously ply the waters near the naval ships guarding against intrusions.

The decommissioned USS Midway, named after the Battle of Midway, is anchored as a permanent museum in the harbour. She was launched in March of 1945 and she served in Korea, Vietnam and Operation Desert Storm. The Navy launched 228 sorties from Midway and Ranger (CV-61) in the Persian Gulf, from Theodore Roosevelt (CVN-71) en route to the Gulf, and from John F. Kennedy, Saratoga, and America in the Red Sea. Her flight deck is 4 acres in size.

Naval engineering practices 60 years ago were quite advanced and subsequent refits over the years made it quite a modern carrier. Newer carriers have a 50 year life expectancy. The United States has 11 active aircraft carriers.

USS_Midway_(CV-41)_decommissioned

Midway prepares to moor at her final resting place at Navy pier in San Diego where she was to become the largest museum devoted to carriers and naval aviation. (10 January 2004).

I also boarded a “Foxtrot” class Soviet submarine, B39, commissioned in the early 1970s. It was based on German WWII era U-boats. It had a crew of 78, was 300 feet in length and displaced 2000 tons. B39 was assigned to the Soviet Pacific fleet. I’m not sure how 78 sailors lived inside this sub for long period of time. I had a difficult time manoeuvring inside each compartment. Each compartment was accessible via a round porthole about 38 inches wide – you went in feet first and propelled yourself through it. The confined space was claustrophobic. They were extremely low tech but lethal and carried 24 torpedoes and some capable of low-yield nuclear warheads. They played a large part in the Cuban missile crisis and other cold war scenarios.

So it was a great summer trip to California again. It’s an extremely beautiful state and the people of California are great. I’m headed out next month for a final visit this year.

Late Night DX On 20 Meters

It’s out there. Last night saw me re-connect with Bill, ZL3NB in Christchurch New Zealand at 0437Z. His signal was 599 and his report to me was the same. There was some QSB but armchair copy using Ham Radio Deluxe and PSK31. My output was set to 25 watts and again this was using my Cushcraft R6000. That’s a distance of 8835 Kms or 14218 miles. Not bad for a low power digital QSO.

ZL3NB_Bill

I had originally worked Bill in April of 2004 and I happened to be one of his first digital contacts at around the same time at 0358Z six years ago. It was nice re-connecting with Bill. He worked a couple of more stations after my QSO and then called CQ for a long time. It was time for bed knowing there was lots of DX floating around despite the low sunspot numbers.


ZL3NB_Station

Bill’s ham shack in New Zealand. The main equipment consists of a Kenwood TS2000 and TS530S (Classic setup with the VFO240 and SP230) along with a Ameritron Amp. Antennas consist of a Mosley TA33 tribander and inverted vee's for 80/40 and 30 meters.

I suspect there’s more DX at that time of the morning, rolling in from the South Pacific area – I just ran out of steam and had to pull the plug.

The steamy heat wave enveloping Ottawa finally broke early this afternoon with some rainshowers and thunderstorms. Temperatures plummeted to +23C and power went out for a few short seconds. It’s time to leave antennas disconnected and grounded before these intense summer storms move into the area. It’s good practice and could save you a bundle if there’s ever a lightning strike close by.
