这个电源能支持百瓦短波机吗
不能,低功率可以

terrific job 73 from kb2uew
这个电源短波机能用吗?测试过没有?
可以,我用在705和817ND、818 上
I bet you do quite well DX wise at 20 floors up with QRP power of the IC-705..
It can be used, but there is a problem. Although the vehicle antenna is well matched, but the efficiency is limited, this operation is not recommended. I am just a temporary play plan. In the long run, it is still better to use a long line of fishing rods.
How much drive does it need to give 100Watt output? What power could you expect from 2.5Watts drive from an FT 817?
If the input is about 2.5W, the output can reach about 65W-75W, and the output can reach about 90W for 3W.
Hi where are you in Guanzhou
感谢分享。
400-470段频率扫描速度,我感觉各大品牌十几年前和现在的产品基本一样,为何不能提高速度?技术瓶颈在哪里?
Nice to see on 0.5 watts of drive you get around 30 watts output. Perfect for what I’m doing...
I am seeing about 100 with a little over a watt in with my 818
Can you show how you wired this up? Did you use the Xiegu CN-20 adapter?
YES
@@BD7PA Did the band switching work?
@@dennisschultz1175 According to the data on the CN-20, auto band switching will be disabled. So like myself we’ll have to switch bands manually. I’m sure somebody will come up with an adapter that will be full functioning in the near future. Seems the CN-20 is nowhere to be found in the States. Even MFJ doesn’t seem to carry this item. Had to order one from Sinotel UK Ltd, and cost around 54 dollars total... I’m going to contact MFJ, and Radioditty, from where I purchased the amp. There might be a much simpler and cheaper way to go!
@@robertmitchum2972 Yes. the simple way would be just to use the PTT and ground on the amp to the 817/818. However, there is some logic and a feedback loop on the CN-20 which lowers the input power from the 817/818 for the best output of the amp. You would lose that if you did not have the CN-20. I am working on a solution to adjust the voltages from the 817/818 to match the band switch inputs on the amp. I am not sure why Xiegu did not address this. MFJ does not import this and does not support it. That means you are on your own in the US. I have 3 emails out to XIegu on this with no response.

What is difference in between XPA-125 and XPA-125B please?
I haven't used the old equipment, nor have I used it. However, the new 125B has good amplification efficiency. It only needs 1-2W to output a large power of about 65%, and 3W can get more than 85% efficiency. In addition, the large screen displays a lot of information, including perfect Input and output parameters, perfect protection, and perfect low pass. That's probably it. Everyone's understanding may be different, just for reference. VY73 de BD7PA
Cannot tell the difference because they are receiving FM radio only.
Ken Chau The performance of receiving short-wave signals is similar.

Did you hook up your AOR AR8600 with ARD300 via IF 10.7Mhz?
Ken Chau Yes
Let’s hear what you picked up.
What is the specification of this mini power supply?
If you leave transceiver at home on mainland, someone can pick up your voice in Hong Kong. Then it is good.
What can this mini power supply provide? Can you upload more details?
Are you living in HK or mainland? Hong Kong has strict rule on all radio communication device. Is the AOR ARD300 a perfect match with AR8600?
Ken Chau Mainland
Ken Chau I am in a good location and can directly receive marine radio signals from Hong Kong
@BD7PA , That’s good!
Great video. Extremely helpful. Thank you
支持一下!

I would like to buy one but the big problem is very slow T/R switching in semi BK mode. It is useless on CW...
Hello. What radio station do you use to connect to the XPA125B test?
Elecraft KX3 please.
I have problem with T/R switching and also with ACC cable. The CN-20 does not work :(
michaelscoofield CN-20 cannot be used with KX3.
OK. The main issue is the T/R switching in semi BK. It is too slow for normal CW operation...:(
