I will be in Hamilton/Bermuda Dec. 12th to 15th. Besides meeting some of the local radio amateurs I will be signing VP9/DK7PE in CW. QSL will be ok via bureau or direct and also SWL QSLs are welcome.


Foto: Exactly 50 years ago, Dec. 4th 1973, I passed my amateur radio examination when I was sixteen years young. The picture shows my SWL QSL I used until this day.

A Vertical Two Element Wire Beam


This time I've tried a new portable beam antenna based on a 15m J-Pole in connection with an additional director. To my knowledge tis combination was never used before. The whole antenna costs around 5USD and weights only 300 Gramms. It took us ony 15 mins to get it working. One great advantage is that you dont need to bring the feedline up to the middle of the vertical dipole as in a VDA system, what makes it much easier to built. Furthermore you dont need to worry about the impdance of 50 Ohms or less. The antenna is fed on the bottom, with a high impedance transformed over a quarter wave stub. This two element vertical beam proved to be very efficient referring to the very good reports I received. It has a gain of approximately 4dB and certainly the salty water brought another few dB on top...

KL7/AH0G Aug. 26th to Sep. 3rd 2023.


Thanks to Kent, KL5T, I had a chance to visit  the very impressive KL7AA clubstation in Anchorage. The KL7AA Team is very strong in emergency communication and also in the training of new radio amateurs, up to taking the VEC examinations. On Tuesday, Aug. 30th., I met Joe (WL7E), who kindly gave me a lift from Anchorage to the famous KL7RA Contest Station at the Kenai Peninsula. By the way, I know Joe since over fourty years now. He is a great CW operator and in the 1980's he gave me the very rare zone #1 for my 5BWAZ on 40m.


Thanks to Steve KL7SB, I was allowed to use this great Multi-OP station - in my opinion one of the best equipped stations I have ever operated from. While conditions were very good, I was able to work several EU QRPP stations, some of them with only one Watt power!

Three Element Balloon Supported 80m Beam (VIDEO!)


Another Lowband Antenna Project


Weather conditions allowed us to pull up an 80m Full Size Vertical Beam based on parasitic elements. The driven element was a J-Pole fed over a quarter wave impedance matching, a parasitic Reflector behind and a Director in front. The antenna wire we used was DX-Wire UL (Ultra Light) with 4 g/m and a strength of up to 60 kg. The balloons could stay up in the air for several days, weather permits, The picture was taken in the afternoon having a slight easterly wind of approximately. 15km/h. During the night wind had completely gone and the wires stood 100% vertical. Transmit power was 400W. On RBN Network we continuosly followed our signal strength worldwide (TNX Wolfgang, DF7PN). For example we were heard at VK4CT RBN in Australia with 24dB, well ahead of our sunset. In the following CW QSOs with Allan, VK2GR and Ron, VK3IO they reported us an outstanding signal with up to 599 on 3.505 MHz in Australia (TNX Allan and Ron).



OJ0/DK7PE/p (Video!)


Operating from Market Reef OJ0/DK7PE/p September 2021. This was DXCC Entity #160.

FOC Con Dinner 2023 in Bad Kreuznach. Three DXpeditioners that operated out of more than 200 DXCC entities.

During our trip to Indonesia we had the pleasure to meet Wayan Rambler YB9BEN and Made YB9CQN in Bali. We had a great evening while talking about many topics and of course Amateur Radio. Thanks to Mr Agung YB9AG I've got the official permission to guest operate from Wayans station. On the Island of Lembongan we met Made Danu YB9ATS and Made YC9BLN. Thanks to Made Danu I was able to do some CW contacts on 15m. As I have no radio with me, I will be a guest operator only. Later this year we will be in Dili/East Timor, what we planned already two years ago. I  hope to get on the air from there as well... 



Strong solar storms sometimes made it difficult to work any DX. During that storms, there was nothing to hear but a big noise from the northern lights dancing above the southern part of Greenland - due to this  PCA (Polar Cap Absorption) I was isolated on the shortwave bands... During that time I went out and took some picures of the incredible Aurora Borealis. As soon the storm was over, the bands were in good condition again. I remember very good openings into Japan, right over the North Pole. On my way home from Greenland to Iceland unfortunately I catched Covid 19. It kept me busy for two weeks, but now everything looks normal again. Many thanks to Peter, OX3XR, and the whole group in Nuuk for letting me use the OX3NUK shack and the antennas.

OY/DK7PE/p 5 Watt QRP Operation


Working on DXFC score brought me up to the Faroer Islands. It was 11°C, windy, rainy and sometimes foggy. Ideal weather conditions for an amateur radio operation. Meeting Caen, OY1CT, was a highlight on my trip to Torshavn. I was running 5W QRP and my vertical Jumper Dipol, switchable from band to band. I was able to fix the antenna in 15m hight, what explains the good signal reports I received even in Japan and South America. The final result was 900 QSOs in four days and a new activated DXCC Entity #161.





After beeing a Shortwave Listener DL K07/463109 for several years, I finally received my amateur radio license when I was 16 years old, back in 1973.


Another QRP Operation from Ireland



QSL via will be ok via bureau, like I do since over 50 years now!


I will always use real QSL cards for the confirmation of a special contact. I like to take photos and design a pretty QSL Card after an operation. QSLs are personal reflections of the human being I have made contact with, even if only briefly. Cards often include comments of interest and I know that a real human being has borne the expense, and taken the time to write a response. It's like receiving a letter, and it is always a pleasant surprise to receive one nowadays. 


For direct QSL requests please use the following address:

Please don't send me IRCs for return postage.


You may request your confirmation via PayPal (for a friend) to:

sending your QSL will not be necessary! 






Amateur Radio - A Bridge To The World

Listening to the radio in the early 1970s was as fascinating to me then as it is today! As a shortwave listener (DL-K07/463109) I was listening on the bands and was happy to receive a rare QSL. While Klaus (DJ6RX), Gun (DL6EN sk), Klaus (DL1KS sk), Hubert (DL1JW sk) and others from the Bad Kreuznach DX-Gang were having their daily DX-contacts with rare stations around the globe, I was eager to get my own transmit permission.


Too young to be a radio amateur?

During the early seventies it was required by law to be at least 18 years old to be accepted for an amateur radio examination. Too bad for me as I was only 15 but ready to start!

With the great support of Harry (DK4PR sk), Günter (DJ8CY) and the DARC Mainz, I was accepted for the examination even though I was only 16. This was an unusual exception at this time! On December 3
rd 1973, I finally got my license with the call sign DK7PE. I was one of the youngest radio amateurs in Germany during these days.


Working DX - which means having radio contact with other amateur radio stations more than 3000 km away - was one thing. But after I had worked 265 DXCC countries, I wanted to visit some of these exotic spots by myself. Egypt was the first rare DX country I visited. And wth the invitation of Keith, VO1LX/SU (now VA3YC), I was allowed to operate this station out of the UN-Camp in Ismailia on the Suez Canal. This was back in 1978.  What a thrill!

In 50 years of Amateur Radio I have visited 178 and operated out of 163 different DXCC countries (see page Call Signs).

Getting an amateur radio license in some of these countries and operating from there wasn't always easy, so to mention Brazzaville/Congo, Ethiopia, Mozambique, Angola, Burkina Faso, Bangladesh or the Central African Republic.

On all of my DXpeditions I have focused on countries that are most wanted on CW (Morse code) and especially on the low bands like 40, 80 and 160m. For this purpose, I designed several antenna systems that fit into my suitcase and work extremely well on all HF-bands. One of my designs is the 3 element Jumper Beam made out of wire. It was described in the Ocober 2011 issue of QST Magazine and several other magazines too.


On my page "QSL Samples" you may find some QSLs I used during 50 years in amateur radio.

The last operation was KL7/AH0G from Alaska August 2023. This was my DXFC #163.


CU on the bands!

Amateur Radio to me is always a combination of travelling, taking photos and operating the radio station from a seldom heard, rare country.

HAM Radio

A typical opertion site at Dondra Head Lighthouse in Sri Lanka. Carrying all my amateur radio equipment and antennas abroad means: one forgotten connector or cable can be a show- stopper...


Taking pictures is always an important  part of my trips. This picture was taken in northern Norway and shows the Northern Lights (Kp Index 4)

A word about today's one-man DXpeditioning


Going on a classic DXpedition offers great excitement to me, just like it does to those in the pile-ups. It’s a thrill to go out and focus on the low bands by using CW, trying out my wire antennas and picking up signals out of the noise, like I have done for over forty years now.


A night on 160 can result in a handful of QSOs and sometimes there’s no contact at all. While a single operator can make up to 8,000-10,000 contacts (SSB/CW) on the higher bands, a low band operation with 1,500 QSOs in one week is a very good result. In Bolivia I was able to work 265 stations on 160m and 862 stations on 80m, providing many of them with “new ones.”


So far I have operated from 162 DXCC entities (see www.dxfc.org).  I am in contact with several stations who have around 300 confirmed 160m DXCC entities. Based on their input, I choose my next destination, provided I haven’t been there before…


On my trip to Bolivia I was carrying 60kg (120lbs) of equipment and antennas with me, which meant excess baggage charges and no mercy from the airlines. For another example, some years ago, on a trip to Southern Africa,  I was asked to pay 1,300 Euros (approx. US$ 1,400) extra fees for additional baggage. So I took a taxi, went back home, took out the heavy parts like the amplifier, etc. and returned to the check-in! High costs for excess weight and baggage are the reason I sometimes have to go QRP or 100 W only.  There are always new additional charges... On the trip to Bolivia for example, I had to learn that bulky and oversize baggage (fishing rods) are charged 250 Euros for each baggage piece, and in each direction.  Wow, that was new to me!


I pay for all of my DXpedition costs and expenses myself, for transportation, oversize and excess baggage fees, accommodations, cancelation fees, QSL printing or whatever. As a one-man operation I have no sponsoring organizations like the big DXpeditions.



Many thanks to those who support my efforts!


Looking forward to hearing you in the next pile-up,


73's Rudi DK7PE




Una DXpeditioning es muy divertida para mí, y lo es para aquellos que trabajan uno nuevo país en una banda o modo difícil. Para mí es emocionante concentrarme en las bandas bajas y en CW, probando diferentes antenas, como lo hice desde mis primeras operaciones en los años setenta. En esta "disciplina" sucede que una noche entera, como la primera en Bolivia, terminé con 29 contactos, a veces sin QSO. Una operación en bandas bajas con 2000 QSO en una semana es un muy buen resultado en mi opinión. Esa es una pequeña cantidad en comparación con el uso de las bandas altas y otros modos, donde un solo operador puede hacer 8000-10000 contactos en una semana. Es muy divertido, pero salir solo, está relacionado con costos notables y, a veces, problemas que uno no encontraría al quedarse en casa. Podría escribir un libro sobre esto...


Esta vez llevé a Bolivia 60 kg (120 lb) de equipos y antenas. Eso significa que se cobrará equipaje adicional, sin piedad. En un viaje al sur de África, me pidieron que pagara 1300 euros adicionales por equipaje extra. ¡Cogí un taxi, me fui a casa, saqué las partes pesadas como el amplificador, etc. y regresé al CheckIn! Los costos extremos por exceso de peso son la razón por la que a veces solo uso QRP o 100 W.


Siempre hay nuevos cargos adicionales ... En este viaje, por ejemplo, tuve que aprender que el equipaje voluminoso (cañas de pescar) cobraban 250 EUR por pieza de equipaje, en cada dirección... ¡vaya, eso fue nuevo para mí!


El coste de estos viajes termina en torno a los 3000 euros, siempre que (con suerte) no ocurran gastos inesperados...


Lo que quiero decir es que pago estos costos por mí mismo, simplemente todo, como transporte, equipaje de gran tamaño, sobrepeso, alojamiento, tarifas de cancelación, impresión QSL o lo que sea. Por favor recuerda, NO tengo patrocinadores como las grandes DXpeditions.


Sí, es divertido para mí, pero también para los que están en el pile up. Lo que me hace pensar es que si un operador que tiene 300 países trabajados en 160mts, me trabajó en la TOP BAND como nuevo país y me envía una bonita QSL con su gran estación, sus motos o automóviles y pone un IRC para devolverle una QSL directa...

Si está contento con haber conseguido uno nuevo, tal vez pienses en esto.


¡Gracias! 73 Rudi DK7PE
