content: I got my ham license. Yay. I am still limited to UHF/VHF though.Currently I only have two 5W dual band handhelds, a Baofeng UV-5R and a Baofeng DM-1801, with the latter being a FM+DMR rig loaded with OpenGD77 firmware. And I have no access to roof for antenna, so reception is awkward at best.73 de BH4FHO.

content: Quote from: radiolistener on December 22, 2020, 05:04:44 pmCost to HAM license in China is province/municipality-dependent. In Shanghai, where I live, the cost is free. China is an ITU Region 3 country. The call sign prefix of mainland China and Taiwan is B. Hong Kong retains her ex-British Empire prefix VR, while Macau has XX.The HAM licensing system has been overhauled in 2013 to address shortcomings exposed in the 2008 earthquake: the simplification of class system, and the removal of Morse from tests, both of which hindered the expansion of HAM circles. There is also tighter integration between HAM clubs and local emergency authorities in the revised rules. A then-recently set up station in Lushan County under the new rules greatly helped with the rescue efforts when the 2014 quake struck, since that station, operating on car alternator power, was the sole way of communication between that county and outside world after communication cables were cut in the quake.The current system has three levels: classes A through C. Class A is the beginners’ class, roughly equivalent to the FCC Technician class, permits transmission in all HAM bands above 30MHz at a maximum power of 25W. Class B, the intermediate class that is roughly equivalent to FCC General class, permits bands lower than 30MHz at 100W on top of Class A. Class C, the top class roughly equivalent to FCC Amateur Extra class, permits 1kW on sub-30MHz. There is no limit on what mode one can use on each permitted bands, as long as your local HAM club and radio authority have access to the documentations, and no crypto is involved.As of callsigns, it is now a lifetime assignment, as it no longer reflects your license class as it used to in the pre-2013 system. I shall forever be known as BH4FHO on the airwaves regardless of my license upgrades.73 de BH4FHO.

content: Congrats! Now onto class B and C.On a side note, the FCC is considering opening up portions of HF bands other than 10m to allow Technician class access to FT8/JS8. I personally think that would be great, would be a perfect funnel for popularizing HF and encourage Technicians to get a General/Extra license and operate on HF.

content: Quote from: cdev on January 10, 2021, 10:46:23 pmHam community varies from place to place in China. Here in Shanghai it is mostly the elderly and the geeks, predominantly males, taking up ham as a hobby. I am not sure about other provinces since my reception do not allow me access to farther away repeaters.It is reasonably popular in Shanghai to use digital modes like DMR and Yaesu System Fusion. I am even considering building a YSF codec module myself (STM32F405 + I2S codec + a lot of DSP code in C) for a Kenwood TK-8100 I fixed up and modded for amateur band. (It would be weird to see a Kenwood blasting out signals encoded for Yaesu.)Quote from: blueskull on December 23, 2020, 01:59:24 amQuote from: mrf245 on January 11, 2021, 08:26:10 amI think the two of you are within VHF/UHF QSO range, according to the QTHR indicated in your callsigns. Have you two tried talking already, maybe over a repeater?

content: Quote from: bson on January 10, 2021, 07:29:15 pmLikely not. Taking the class B exam requires one having class A certificate for at least 6 months. And taking class C requires operating a class B station for two years. I am about to head to the States before the next Shanghai class B exam can happen, so I am likely stuck at class A for now. OTOH I will be taking FCC General class to get a similar spectrum access while in the States.

content: The DBJ2 is a dual band antenna that works well is fairly easy to construct - and has some fairly good gain for what it is.Its omnidirectional and made out of that old style 300 ohm twinlead and a short stub made of coaxial cable.You could make a small hook for your ceiling and only hook it to it when its in use, letting it hang. Nearby objects detune it a lot. You'll have to make it a tiny bit larger because your band is slightly lower than the US band. The original version (inside a specific Lowes SKU of PVC pipe) is extremely popular in California because it works quite well and also has the benefit of costing almost nothing to make..But, if you live in a steel framed building, unless you have a balcony or very large windows, your options will probably be even more limited. But if you have just a little bit of space, something like this makes a nice antenna, especially if you are up a bit. Make sure its vertical because its pattern puts most of the signal around the horizon.Quote from: blueskull on January 14, 2021, 05:55:22 am

content: WA5VJB makes a PCB material log periodic that works well on 440 Mhz and is quite compact. I have one here and use it to listen to repeaters in this area. its quite directional. I taped mine to a piece of posterboard to protect it and make it easier to handle. I would guess it has around 9DB gain and the 70 cm band. It also works on higher bands. It was a good value at around $15. It covers 400-1000 MHz.It would likely vastly extend the range of a HT like the Baofengs. It would seem to me to be almost a sure bet it would be useful to you your new hobby. If you use 440 .Its listed herehttps://www.wa5vjb.com/products1.htmland you can find it for less if you look. I paid about $15 on ebay. I would not mount it outside because it catches a lot of wind outdoors and in a strong wind, the PCB traces would get broken. But indoors it works great.
