Testing a PRC2000 on 40m USB

Last Friday a colleague from Belgium and I tested some manpack radios, among which was the PRC-2000. The PRC-2000 (also known as Callpack RT-2000) was built in Great Britain by M.E.L./Philips. It is a fully transistorized radio for portable and vehicle use from the late 80s.
The PRC-2000 is a versatile microprocessor controlled HF transceiver for use in tactical field operations. Within the 1.6 Mhz to 30 Mhz HF frequency band , the transceiver can operate on any of 284.000 cannels spaced at 100Hz intervals, to provide single side band LSB/USB voice or data communication, or continuous wave CW Morse communication. In addition to manual channel selection, frequency and mode data for up to 10 channels can be preset in non-volatile memory for immediate recall as necessary.
Here you can hear it in action on the 40m amateur band:

The PRC-2000 operating modes are USB / LSB / CW / DATA. Antenna tuning is fully automatic. The output is 20 watts on high power and 4 watts on low power. As options, there are solar and hand generators, as well as an amplifier.

Sardinia (IW0UII) with the 320

This is a video of another QSO with Sardinian station IW0UII (operator Alex). I made this QSO about one week ago, immediately after having made some tests with Alex (ON4FB).

Sardinia (Italian: Sardegna, [sarˈdeɲɲa]; Sardinian: Sardigna or Sardinnya [sarˈdinja]) is the second-largest island in the Mediterranean Sea (after Sicily).
In 1479, as a result of the marriage of Ferdinand II of Aragon and Isabel of Castile, the "kingdom of Sardinia" (which was separated from Corsica) became Spanish, with the state symbol of the Four Moors. Following the failure of the military ventures against the Muslims of Tunis (1535) and Algiers (1541), Charles V of Spain, in order to defend his Mediterranean territories from pirate raids by the African Berbers, fortified the Sardinian shores with a system of coastal lookout towers.
The kingdom of Sardinia remained Spanish for approximately 400 years, from 1323 to 1720, assimilating a number of Spanish traditions, customs, and linguistic expressions, nowadays vividly portrayed in the folklore parades of Saint Efisio in Cagliari (May 1), the Cavalcade on Sassari (last but one Sunday in May), and the Redeemer in Nuoro (August 28).

Canary Islands: No. 20 with the PRC-320

Yesterday I made another QSO with the Canary Islands and I have already received the eQSL. It was a QSO on the 20m band with EA8DO (Manolo) from the island of La Palma, also known as La Isla Bonita. I got a signal report of 59.
This makes the 20th entity confirmed by eQSL so I am closer now to my 25-country target. Here you can see the video of the so much awaited QSO that would provide me with the new DXCC entity confirmation:

La Palma, like the other islands of the Canary Island archipelago, is a volcanic ocean island. The volcano rises almost 7 km (4 mi) above the floor of the Atlantic Ocean. There is road access from sea level to the summit at 2,423 m (7,949 ft), which is marked by an outcrop of rocks called Los Muchachos ("The Lads"). This is the site of the Roque de los Muchachos Observatory, one of the world's premier astronomical observatories.

Clansman 2.4m whip and counterpoise system in action (EA1AQ/P)

On this video you can see the standard 2.4m whip in action together with the Clansman counterpoise kit. EA1AQ/P (Juan) makes a QSO with Swiss station HB9ESA (operator: Rico).

We only used 3 out of the 4 radials available in this kit (you can see the unused spool on top of the table. Despite the very strong QRM from some digital transmission, the PRC-320 did the job. The 1.1Ah battery you see on this video is also more than enough for a day of operation.

Finland (OH6AC) on 15m (Spanish)

This is the video of a QSO with Finnish station OH6AC (operator Jyrki) on the 15m band, using my Yaesu FT-857D transceiver, a 4m whip and the FC-40 autotuner. As will be able to see on the video, Jyrki speaks Spanish very well.

The OH6AC callsign belongs to the Lapua Radio Club. The Club was founded in 1962 by members of Lapua High School Physics Club. There are nowadays 41 members in the club from Lapua and the nearby district.
OH6AC is located high on the top of Hill Simpsiö at 130 meters which provides ideal circumstances for amateur radio activities on UHF, VHF and HF-bands. Besides an HF-amateur radio station the club maintains two FM-repeaters.
The club is also very active in contests. You can find more information about it at http://www.oh6ac.net/.
