ham radio with a drone

I recently got a Wouxun KG-UV8D+. This radio has cross-band capability. My aim was to lift it up using my DJI Spark drone to make long distance contacts, or hit distant repeater that I can’t usually hit from my home. Unfortunately the radio as is, is too heavy. Looking on-line, it looks like the DJI Spark can lift about 150gr.

So, I stripped down the radio, removing all plastics and battery, and replacing the antenna with a smaller one. For power I used two small 300mAh LiPo batteries connected in series.

Wouxun KG-D901. Nigdy więcej.

Witajcie.

Dziś postanowiłem, że że chętnie wypróbuję nowe radio DMR + FM od Wouxuna. Skusiłem się troszkę w miarę udaną konstrukcją TYTERA MD-380, ale radość szybko przeistoczyła się we łzy wściekłości.

Co do samego wyglądu i materiału z jakiego wykonane jest to radio to nie mogę powiedzieć nic złego. Jak na ryżowca to jest fantastycznie. Problemy pojawiają się zaraz po włączeniu.

1. Pierwsze wrażenie

Jak każdy krótkofalowiec lubię szybko rozpakować nowe radyjko i zaliczyć pierwszą łączność. Od tej łączności zaczyna się sympatia do radia albo i nie. Wouxun KG-D901 to FM oraz DMR na jednym pokładzie i właśnie od FM chciałem zacząć. Ustawienie QRG lokalnego przemiennika nie jest trudne, ale ustawienie CTCSS to już przegięcie w kombinowaniu. Bez kabla i softu nie podchodźcie do tego radia. Pomyślałem sobie ja, że skoro tak to może prościej będzie pogadać w DMR, schemat podobny. Ustawiona częstotliwość, CC, slot i już .... i uja... nie działa. No coś nie trybi i koniec. Oczywiście bez softu nie wpiszecie swojego znaku aby był widoczny w sieci DMR. Na szczęście mój kolega Arek SQ7SCC z naszej grupy przemiennikowej zaopatrzony był w stosowny kabelek i na dalsze czynności udałem się do niego. Program ze strony producenta działa poprawnie z tym trx, radio jest czytane bardzo szybko. Sam soft podobny jest bardzo do oprogramowania Motoroli MOTOTRBO zatem jeśli ktoś ma odrobinę pojęcia o programowaniu radyjek dmr poradzi sobie bez problemu.

2. Czemu nigdy więcej ??

Zacznijmy od tego, że radio posiada po 16 kanałów pamięci w każdej strefie ( ZONE ) co jest zupełnie naturalne w radiach dmr. Nie mniej jednak ten model wouxuna może mieć maksymalnie 2 strefy co daje 32 kanały, ale to nie koniec nieporozumień. Zone 1 jest strefą z kanałami DMR a Zone 2 jest do analogu, a zatem można mieć max 16 kanałów DMR i 16 anali. Co za wełniana istota to wymyśliła ?? Nawet nie da się wpisać wszystkich repów cyfrowych w SP !!!

Nie można dodać kolejnej strefy ponieważ nie pozwala na to oprogramowanie producenta

Być może to kwestia softu i kiedyś coś poprawią, ale na dziś w moim radio tak to wygląda. Poniżej zrzut ekranu z tego.

Kolejny zonk czai się w liście kontaktów. W każdym radiu jakie mam czyli HYTERA, MOTOROLA czy nawet TYTERA można i trzeba wręcz wpisywać listę kontaktów. Tutaj możliwa jest ta funkcja, ale... kanały do listy można dodawać wyłącznie jako grupowe, a zatem 260, 2607,260042 itd... ok, ale już 2607002 czyli wywołanie Arka SQ7SCC jako kontaktu indywidualnego wpisać się nawet nie da bo program jako “name” czyli nazwę wyświetlanego kontaktu przewiduje wyłącznie 5 znaków zamiast 6 lub więcej a zatem arek będzie się wyświetlał jako SQ7SC zamiast SCC.

Jak by tego było mało nie można kontaktów indywidualnych przenieść na listę, widoczne są tylko grupowe. Każdy taki kontakt można poprawić wpisując go najpierw z komputera a następnie edytując go ręcznie w radio. Jeśli jednak ktoś przez to przebrnie i podwójnie wpisze i edytuje kilkaset kontaktów w samej SP to chylę czoła, ale dostanie nerwicy jak zaczyta radio poprzez program, na liście zobaczy te kontakty bez ostatniego znaku :)

Następna zagadka to reset do ustawień fabrycznych, jest taka funkcja ale nie działa :) może i coś się resetuje ale na pewno nie ustawienia i nie pamięci. To są na szybko znalezione ogromne jednak błędy w oprogramowaniu tego radia. Kolejną wnerwiającą kwestią jest odbiornik. Z tego samego miejsca 3 inne radia dmr w tym jeden chińczyk odbierały nasze przemienniki DMR w SP7 bez żadnego problemu a Wouxun KG-D901 jak zaczarowany - milczy jak grób. Zmiana anten pomogła nieznacznie na plus co oznacza, że albo odbiornik jest fabrycznie padnięty albo ten typ tak ma i woli się nie przemęczać. W drodze do domu próba w direct na FM. Odległość od korespondenta max 2 km w lini prostej, anteny się widzą i ręczniak dostaje jakiś zgrzytów w odbiorniku, coś w nim warczy i odsłuch to męka. TX jest chyba porządne bo dostawałem raporty od kolegów innych dzielnic i słyszeli mnie dobrze, ale ja musiałem włączyć DSP w uchu aby domyśleć się co mówią.

3. Podsumowanie.

Jak dla mnie Wouxun podpadł za sprawą beznadziejnego softu w radio oraz do programowania. To żenada i powinno to zostać bardzo szybko poprawione bo to radio nie nadaje się na teraz dla krótkofalowca. Straszny odbiornik - wiem, że tam za wiele nie ma, ale na litość uszu, przecież muszę coś słyszeć chcąc zrobić łączność. Jak dla mnie porażka po całości i nie zamierzam im dawać więcej szansy. MD-380 jako bezpośrednia konkurencja pokonuje tego KG-D901 malutkim paluszkiem oferując chociażby experymentalny soft, który działa doskonale. Na dzień dzisiejszy nie polecam kolegom zakupu tego radia, to FM z ograniczoną ilością kanałów i opcją DMR.

Antenna Feedback:

I didn’t want to make this post as it detracts from what we do. The sheer response from people regarding radios, antenna combinations and what they use was fascinating but also enlightening. We also had emails from hardworking folks that have bought fake items from Ebay and had damage to their radios as a result. I’ve since purposely purchased some of the fakes and had people send us some of the Antennas they have, so we can get a closer look.

I cannot stress this enough, fake antennas are a real problem, and you should never buy an antenna from Ebay unless it’s a known store with an actual physical address incase of problems. Stick with stores that have their own independent online presence to make a purchase so you have someone to go back to if things go wrong. Genuine Antennas from Diamond cost £15-100, they are pre-tuned and SWR to 1.1:1 or 1.5:1 by the manufacturer. The fakes we tested started at 4:1, radio damage could easily occur at this level.

For the purposes of testing it should be noted we used an old radio given to us. This way we can use stock antenna testing to compare results and the SWR of the antenna at four watts. We used this as a base to compare, with a standard, albeit old, from the box set up, we can hit a repeater some 4 miles away. The signal strength on the stock antenna is about half of the LCD scale. Not overly scientific for this, but it shows real world use and some people may just find that simpler.

The first item drawn is a stubby Antenna claiming to be made by Diamond. The actual version made by Diamond is an RH-3 which is terminated in a BNC connector, or the SRH805 which is an SMA male. (I’m not aware of an ‘S’ suffix on this antenna but may refer to a Female SMA version.) The real antenna itself looks like a plain black dome with a single gold band around it and the quality of the real unit is superior in feel as well as the way it looks. The lettering also on the genuine article is a clear font with an airplane motif. There is no gain on these antennas, they are made to work in a shorter range. The fake antenna had a high SWR on it from the onset and the transmission range was half a kilometre. That’s not great performance but the high SWR is going to have an effect. This could not hit the repeater, and if I am open about this, I don’t think the genuine item would have done so either. It’s beyond the capabilities of the antenna at a mere 4 watts. The fake item can be bought for as little as £2.50 including postage, that should speak volumes on an antenna that retails when genuine for over £20. If something seems too good to be true, it often really is. Even if you used this clone antenna on a scanner, the results are just as terrible overall.

Next out of the bag was a ‘stock replacement antenna for Baofeng or Wouxun’. I cannot genuinely get over how low a quality this replacement ‘duck’ antenna is. It’s so poorly made it arrived damaged in the mail. The 3.25” antenna has a paper seal on the bottom that denotes UHF 400-470 MHz and the lettering is faded from new. The internals of the antenna were not even assembled correctly and it’s held together with PVA glue that is not enough to hold it into the outer shield. This is nothing more than an SMA male screw one end with a 55mm copper spring on the other. I thought this would cause real radio damage so tested this one last. Reception was poor, the repeater could not be hit and in testing the actual distance for quality transmit was a little over half a kilometre. I would say that it’s what you get bundled with some cheap import radios but that’s unfair to the cheap and nasty import radios. They actually have better quality antennas than this. Overall the performance was marginally better than the above antenna, but I would not want to use this for extended periods of time. Key time on this was kept low to prevent radio damage with a 5 second key maximum. As a scanner antenna, I really do think you would be better off with a paperclip as the performance was poor. Although hailed as a direct stock replacement for Baofeng and Wouxun, the Baofeng uses SMA female antennas while the Wouxun uses SMA male, it won’t work with both.

Next out of the bag is a Nagoya typically sold as a NA771 or similar variant. This is where this gets really interesting as the Nagoya Website has these listed as fakes from the onset with details of what to look for. The biggest fact to note is that the antenna has printed on it Made In China. This is a fake for sure and one of the biggest clues. ALL Nagoya antennas are made in Thailand as that is where the factory is located, even the Nagoya website shares this fact. The packaging itself also shows a spelling error and labelled ‘Flexiable Spring Whip’. The hologram and other tag information is a sticker and not printed onto the packaging directly as per the genuine article. The vinyl used to package the product feels thin, the corners are not cut as rounded and even the antenna itself does not display the correct logo with its trademark triangle in the ‘A’. These are typically also sold by a drop ship importers under many accounts on Ebay. ‘One warehouse to con them all’ as someone said by email. (Labelled as DUS International imports, Greenford, UB18 7HK, UK) They can be bought for £2-5 and the genuine one costs around £10-15 and is very different. Even the antenna shape itself is different on the genuine article. The SWR was strange. With the antenna straight it was a little over 4:1 and with a flex it crept up. I’m not sure if it’s damaged/faulty but it was variable. In testing it got the repeater to activate which was a first from the fakes, but the receive signal was poor at one bar at best. In real world use testing the range was over a kilometre but the quality of the signal was low. As a scanner antenna it works fine, it does not excel at it but it is functional. The flex of the antenna can leave it leaning over with the radio stood as it never quite seems to support itself.

Our large genuine Diamond antenna on the test radio produced full bars on the repeater by comparison, the performance difference is clear.

Our best advice is do not buy antennas from Ebay. You are most likely not getting the bargain you had hoped for. For the US, purchase from PowerWerx to be sure it’s a genuine product with excellent support. For the UK/EU try RadioWorld for antennas. This way you know you are buying a genuine item and have support if anything is wrong. A radio can be a large investment, Ebay for its sins is not the place to scrimp on second rate antennas that will affect the lifespan of your radio to save a few bucks. I’d never buy a second hand radio from Ebay either, you simply don’t know how it’s been treated or even if it’s been keyed with no antenna, poor SWR for long term use etc. If you need a radio, buy it new and buy it from a dealer so you can go back and knock on the door if things are wrong.

The antenna list we use is all from Diamond and we can verify the usage of them first hand. For portable discreet carry we adopted the Diamond SRHF10 flexiduck. For mobile operations and vehicle use the Diamond SRH771 and a new comer which fits between the two is the Diamond SRH 815S. This is a 6” super flexi antenna with some real gain to it hitting the repeater in two areas which is a real surprise. Once you get past the thinness of it, it’s a real performer but it does require investment due to the price.

We have been asked about what type of microphones we use and our other accessories. This is not really our area of expertise but we have merely followed it through as a request for our loyal customers and fans. Please do not email asking for more information. For those that wanted information on the Wouxun KG-UV9D, we do have one and use it. The software is still early days for the radio so most of the features given are not yet able to be utilized due to the software lacking its function and control. The airband monitoring is a nice addition but the go to radio is still the KG-UV8D as it’s a real workhorse that performs, something the 9D has yet to prove itself in.
