SM6POP Amatörradio Ham radio antenner Anders Karlsson Welcome to look into my toolbox! Here is some tools between antenna and earth that I have used, maybe you also find something useful in the field of amateur radio on the page If you click on the The radio workshop you can see a little about my ham radio repairs. I accept ham radio equipment for repair and service as time allows and access to parts and service manuals. If there is something in the toolbox you want to comment on or are missing, please contact me under Contact. The page is best viewed in Windows.

The radio workshop Welcome to my radio workshop! Here I repair and service our stations and accessories. My business is at a hobby level as I have a regular job during the day so repairs and service are only accepted to the extent of time and desire. I also choose the type of repairs I undertake depending on the availability of service manuals and spare parts and costs associated with the repair. Old cb-radios should preferably stay at the owners home when the ravages of time and screw-happy novices often put the radio in a condition that is not worth repairing. You are always welcome to contact by using the contact form at the bottom of the page. You can also contact me if you repair/modify on a slightly simpler level yourself and need support. In that case, write your phone number in the contact form and I will call you when the opportunity arises. An IC-7300 on the repair bench Tips from the coach. If you do not have full control and the right instrument park, never open the station to repair, mod or "tune" it. Never go into hidden service menu to "trim" it. Don't touch anything that works! Use well-tuned antennas, preferably antennas in resonance or close to resonance. All contacts and connections in the antenna system must be well connected and with good contact. Make sure you have no RF currents back to the shack. In case of high mismatch in the antenna system, use an external tuner instead of the radio's built-in one. For long transmit cycle digital modes, do not run at full power. Do not build the radio in such a way that the radio's fan cannot get rid of the hot air from the station. When connecting power amplifiers, modems, microphones or other non-original peripherals, ensure that all connections are correctly configured. If the radio is not working as it should, do a factory reset before you decide to send it in for repair.

My remote station Here is some information about my remote station. The mast stands on a hill outside Åmål about 1km from home. The main antenna is an 80m dipole set up as an inverted V and with step feed. I also have other antennas in the mast, which is also equipped with a sled. The steps from the dipole go into these baluns that I built and the feed then continues as coax into the autotuner, The antenna can be tuned without problems on all bands from 160m to 10m. The station consists of an IC-706MKIIG, remote control from Remoterig and a 4G router. The autotuner comes from MFJ. There is also a Windows computer with Chrome remote desktop installed so I can get into the router's and Remoterig's web interface, pull out the antennas and control the antenna switch from home. The remote station also has a Web-SDR that I connected with my radio at home with the help of Omnirig so they follow each other in frequency, mode and mute at tx. The SDR receiver is an Air Spy and the software is Spy Server installed on a Windows computer. The software at home is SDR Console also installed on a Windows computer and with the screen mounted directly above my station. I can broadcast with the station at home and listen to interference-free reception with waterfall and spectrum scope from the remote station. Remote control of antenna contacts in case of thunder. Around the remote station, there is a collaboration with Åmål Municipality so that it can be used in social crises. At the moment we are working on a solution to be able to control it via radio link and thus be independent of the internet. Reserve power for the power supply is also underway. The station also has a special signal - 8S6K

My antennae Here are the antennas I use at the moment. See also under the remotestation tab. At the bottom of the page there are also some tips and links for those of you who like to build your own antennas. The beam is a Hygain Explorer and it has the bands 30m, 20m, 15m and 10m. Above it a warcbands dipole and at the top a vertical from Diamond for 2m and 70cm. It's all mounted on a sled so I can lower the antennas to the top for easier servicing. Here is the rotor that I turn the antennas with. It sits on the floor in the attic and I built it from a Permobil engine, two gearboxes and chain drive. The rotor is operated with a control box from CDE. I use this antenna for the 40m and 80m bands. The upper part for 80m is slightly shortened and thus adapted for the attachment points I have access to but performance and bandwidth is basically equivalent to a full length dipole. The coils inductance is 30 Mikrohenry, read more about the coils further down the page. Antenna analysis 80m Antenna analysis 40m Here is a picture of my 80m vertical that I have mounted on my boathouse. The antenna has a coil in the middle and uses the tin roof of the boat house as a ground plane. If you don't have access to the metal roof or the like, it works just as well with counterweight ropes. Antennas for smaller gardens Shortened antenna for the 80m band that works well. This antenna is much shorter and thus narrower, but works to tune with the radio's internal tuner over the entire band with good results. The coils are of the same construction as on my wire antenna for 80m and 40m further up the side. They are wound on 50 mm electrician's pipe. By wrapping with RK el. FK1.5mm2 automatically gets a "pitch" of 1:2. 45 turns gives the desired 30uH. A 140 mm pipe length is used for the winding itself, but a 160 mm pipe is used to accommodate the reliefs. The antenna is previously posted by SM4FPD, thanks Roy for a good antenna for small spaces. Really good Windom antenna for all bands from 40m to 10m including the Warc bands. Works very well and goes on all bands including the warc bands without too high SWR. Can be tuned with good results on 6m but works poorly on 80m. Avoid running the coax parallel to the antenna wires and preferably use a - RF-choke or similar to prevent RF to the shack, which can be a problem with Windom antennas. I myself have some tube ferrites on the coax just below the balun and have never noticed any RF in the shack. I bought this antenna but it is easy to build yourself. The antenna is designed and sold by Nigel Booth - M0CVO This is another good multiband antenna with small dimensions that also works well even on 80m.

Troligen Sveriges dyraste stege då min dotter som monterade ihop den fick 4 kronor för varje stegpinne :-) Här kan man se de låga förlusterna vid en stegmatad antenn. Kan man bara stämma av den så är furlusterna försvinnade små. Längkarta på dipol och steglängder En linkkopplad Anneke-tuner avsedd för stegmatning. Vill man slippa tuner går det bra att koppla in olika steglängder för att hamna rätt. Baluns and chokes Here, 2 baluns are suitable for several of the antennas on the side. They are wound on the toroid core Amidon FT 240-43 which is easy to find for purchase._cc781905-5cde-3194-bb3b-136bad5cf5 50d_Maxw power ca. If you need higher power endurance, you stack two cores, maximum power 1000w. If you want to read more about baluns and how you make them, visit Wolfgang Wippermann's (SK) website. He was a guru on baluns and on the website he shares the knowledge of building well-functioning baluns. https://www.wolfgang-wippermann.de/ Här på VK6YSF hemsida hittar du också bra beskrivningar hur du bygger baluner. https://vk6ysf.com/balun_choke_balun_low_vhf.htm You can build an RF choke by wrapping the coax around a plastic tube, a so-called "uggly balun". The coax wound around a toroid core provides a wider bandwidth RF-Choke. You can see the number of turns and frame/toroid here.

Emergency contact What is emergency contact? Emergency contact is an alternative method of communication that can be used when a socially critical method of communication no longer works and thus exposes the public to danger. Download SSA's translation of the IARU Emergency Contact Guide FRO is an important player when it comes to emergency communications, visit their website here. Öland's Radioamatörer has a very interesting project about emergency communications, which you can read about here. Under construction
