昨天考试今天证书编号就出来了，有关部门的办事效率真是高。求助推荐短波电台以及配套的天线等设备，总预算不超过人民币4950元电台的需求如下： 1. 频率覆盖HF和50MHz 2. 有核准证 3. 功率不超过15W 4. 有频谱图 5. 支持FT8(新手期暂不考虑SSB) 天线的需求： 1. 目前住所没有除室内小环天线之外的架设条件，只考虑能野架的非固定天线 2. 可以接受成品天线和diy天线，但至少有一个全尺寸成品天线做保底其他设备： 1. 天分仪、天调 2. 电源由于没有在二手平台上购物的经验，以上设备优先考虑购买全新，大家有没有比较好的设备推荐？谢谢！

感觉可以上891 + 电源 + GP，不过**很极限**，得找到优惠的价格才行我当时入手全新891的价格约4500，所以才会感觉楼主的预算“可行但没什么余量” 估算一下，天线大约一两百（我的GP是MA-12，但是这款价格偏高；我其实还不能确定有没有一两百的、做工比较整的成品GP）电源一两百大概也都可以解决

请教友台电源怎么搞，我也是今年的新B，上了一台891和MA-12的天线，但是电源好像帖子不多，不知道怎么搞。。。。 @"BG5CVB"#p101996

@"BI2QGI"#p102004 入门摸个求精，再不行搞带接线柱的服务器电源，线性电源等设备价格上来再说（）

这个预算要有频谱图的，新机设备貌似只能选G90和X6100，电源便宜的方案买改好13.8V的服务器电源，网分买最便宜的VNA拼夕夕180，用小防水盒+5.6拉杆还有一些M10螺丝可以自己DIY GP天线。如果不用频谱和内置天调买891预算应该也勉强够

@"BI2QGI"#p102004 简单一点的话根据你的设备规定的输入电压范围和最大电流，去淘宝找稳压电源，类似于大充电宝。一般是给广场舞音箱和电子琴或者电吉他这种设备供电的。我之前买的这种都是DC接口那个圆口，然后买个DC转你的电台电源接口的线。这种价格会比友台说的服务器电源高一些，但是胜在简单，可以移动，有成品可选。另外我记得之前的帖子有友台做线，加诱骗芯片转type-C口接大功率充电宝的也有。 [upl-image-preview uuid=710d7b1d-5981-4c3c-9946-bbab6989b9a0 url=https://storage.hamcq.cn/2026-08-17/1786952801-714158-20260817154540-68-50.jpg alt={TEXT?}]

G90就很符合啊, 而且还有天调,天调还很给力

找人帮你带7300，电源200就能搞定，天线先搞个端馈，就别算在预算里了。

看了一下价格，这个预算可以买X6100、MA-12再上一个端馈天线还有剩

Passed the exam, new B seeking recommendations for shortwave equipment.

BI4PID

Yesterday's exam results and certificate numbers were released today, which shows a very efficient process by the relevant authorities.
I'm looking for recommendations for shortwave radio and related equipment, such as antennas, with a total budget of no more than 4950 RMB.

The radio station's requirements are as follows:

Frequency coverage: HF and 50 MHz
Certified
Power does not exceed 15W
Includes a spectrum plot.
Support FT8 (SSB not considered for beginners initially)

Antenna requirements:

Currently, my home lacks the infrastructure to install anything other than a small indoor loop antenna. I am only considering non-fixed antennas that can be used for field operation.
We accept both finished antennas and DIY antennas, but at least one full-sized finished antenna must be included as a backup.

Other devices:

Astrophysical instrument, astronomical tuning
Power supply

Since I have no experience buying used equipment, I would prefer to purchase new items. Could anyone recommend some good options? Thank you!

Ethan

BI4PID 好像完全符合的说的是ic705或者ftx1?
好吧。。价格不符合。。😂

G90N + GP antenna

BG5CVB

I think I could go with the 891 + power supply + GP, but...Extremely challengingI need to find a good price.
When I bought a new 891, it cost around 4500 yuan, so I understood why the original poster felt that the budget was "feasible but lacked sufficient funds."
Roughly speaking, an antenna should cost around two hundred (My GP is the MA-12, but this one seems to be priced too high; I'm not even sure if there are any well-made, finished antennas available for around two hundred yuan).
Power sources of around 100-200 watts should be sufficient.

BI2QGI

Could you please advise on how to handle the power supply for my station? I'm a new ham this year and have set up an 891 and MA-12 antenna, but I haven't found much information about powering it. I'm not sure how to proceed.

BG5CVB

BG5CVB Oh, and by the way, after seeing the subsequent replies, I'd like to add a few more points.

The spectrum of 891: 891 has a spectrum, but it's made up of individual pixels, and the resolution is impressive. It's not useful for strong or weak signals; it's essentially a waste of space. Therefore, the main poster considers that other radio stations with better spectrum diagrams are perfectly fine.
Regarding Tian Dao: If you're not aiming for absolute precision, and just want something quick and easy, consider borrowing a friend's expertise. You can pre-determine your GP's resonant points in each band (similar to how MA-12 works) and mark them clearly. This way, when setting it up next time, you only need to make minor adjustments (or even skip the adjustment altogether). This will also save you the hassle of having to calculate the Tian Dao manually.

BG5CVB 是成都m哥卖的那个天线吗

BG4QBF

Please check out the x6100.

BG5VMD

BI2QGI If you're just starting out and want to get a basic understanding, I recommend trying a simple power supply first. If that doesn't work, then consider purchasing a server power supply with terminal blocks and other related equipment, and we can discuss the pricing at that point ( ).

BG6XXW

BI2QGI In simpler terms, based on the input voltage range and maximum current specified for your equipment, find a stable power supply on Taobao that is similar to a large power bank. These are typically used to power devices like karaoke speakers and electronic keyboards or electric guitars. The ones I bought previously all have DC connectors (round ports), and then I purchased a DC-to-your-radio's power adapter cable. These will be more expensive than the server power supply mentioned by "friend station," but they are simpler, portable, and readily available as finished products. Additionally, I remember seeing posts from "friend stations" where they sold cables that convert Type-C ports to connect large power banks.

BG5CVB

BI2QGI Initially, I didn't know either. I bought a fake outdoor battery from someone on Taobao. However, the store is now closed, and I haven't used that battery since.
Currently, I am using the "Qingjing" power supply from Teacher 5AG. While some enthusiasts have mentioned that "Qingjing" can damage audio equipment, my experience so far has been positive.

BG7MGW

This budget should include a spectrum analyzer. The new equipment seems to only allow for the G90 and X6100 models. For the power supply, I recommend buying a cheaper 13.8V server power supply. For the network interface card (NIC), I suggest purchasing the cheapest VNA from a DIY supplier for around 180 yuan. You can also use a small waterproof box, a 5.6-inch puller, and some M10 screws to build your own GP antenna. If you don't need a spectrum analyzer or an internal antenna tuner, a budget of 891 yuan should be sufficient.

BA7NNC-JOE

The G90 is perfect, and it also has Sky Command, which is very powerful.

BG7NOD

Find someone to help you with the 7300, and you can get a power supply for around $200. Also, don't include the antenna in your budget; just get a basic one.

BI4PID

I checked the prices, and with this budget, I can buy an X6100, a MA-12, and an additional directional antenna.

BH1LAF

主要还要能上证，大证申请时间长，小证比较方便

BI4PID

BH1LAF Indeed, I prefer to use the Shanghai Stock Exchange, so I mainly consider devices priced at less than 15,000 yuan.

prfvvv

The price of 4950 seems very strange; why not 5000?

BI4PID

prfvvv The expenses related to attending this exam, such as transportation costs, have been removed.

Liridice

BI4PID If it's permitted locally to use new B devices with a cost of 15,000 or more, then there's no need to buy devices costing less than 15,000.

Azunyan

It's recommended to use the G90N and X6100, as the housings for long-term FT8 operation can get very hot.

BI4PID

Azunyan 看了一下G90
感觉相比X6100支持的频段要少一些，而且需要另外买电池，FT8模式也不如X6100方便

BH9BZB

Get it all in one go: FT891 + MA-12GP, avoid making a mistake!

BI4PID

BH9BZB FT891+MA12天线就超预算了，X6100+MA12就刚好在预算范围内
