Hello, is there a finished and marketed product? Mod. both bands has 1.8 / 54 mhz and Vhf 142/148 mhz.
Thanks for info and price.
Hi , I am not selling an amplifier (Only some parts). Case and Firmaware available immediately, the remaining modules are made to order the lead time is 2 months. For a complete assembly you must buy some parts available on Ebay AliExpress, Ebay. The firmware and the casing can be adapted to the modules of W6PQL.COM and EB104
Awesome post! Keep up the great work! 🙂
Do you sell the Mercury III amplifier as a kit? If so, what is the price?
Thank you, Rick, KC3DR.
All parts for the complete assembly will not be available, therefore it is not a KIT, only parts separately))
Hi. Can you send a price list for the parts and lead times. Heard this amp discussed on 80m and seems to have gotten glowing remarks. Best wishes.
Parts and prices available immediately here
Hi have you a price list and delivery availability?
Best 73 – Gordon GI6FZI
Unfortunately there are no parts available
cuando crees que estarán disponibles los kit completos ?
realmente me parece un excelente producto y quiero comprar uno armado o un kit completo para armar la nueva version III
te felicito un lineal muy bien diseñado y actual y lo mas importante todos los compradores están satisfechos ….
Hola Eduardo, mi trabajo principal me toma toda la semana, e dedicado el fin de semana y los tiempos libres para emprender este proyecto . Tardare 2 meces en tener una de estas piezas listas
It exclusively your opinion
Looking for pricing and availability of parts.
Parts not available up to 2 months
For all readers, i am one of the many happy and satisfied customers using a Mercury III for a year now.
I use it every day at full power of 1200W driven by an IC7610 with just 40W output and the IM products at that level is always -37 db.
Reports received are that my TX is very narrow with no splatters at all.
It works warm at long periods of TX. Never hot
Fan is very quite and automatic band switching is very fast with just one PTT press.
I have owned in the past the Expert 1.3K and also the PalStar 1K and by far this kit works much better besides that it look nicer
How do I buy parts for modules?
buenas tardes estoy interesado en el amplificar me gustaria si pudiera tener una llamada con tigo por favor 9195249030 gracias
Como puedo adquirir un kit? kenny, no veo como puedo comunicarme con vosotros.
I will like to know, how to order this amplifier, ship to Miami , Florida.

Hi, What type of 50V power supply will fit in the case? I’m assuming you will need at least 40A.
Hi, the Case is compatible with Power Supply of communication servers, you can use ETP-48100 server (53 Volt, 57 amps)
I wish to bye the full board set but can’t change my address do you ship to the UK?
Your (built controller board) shows out of stock, is it possible to purchase the built controller board? Of course I plan to purchase all the other PCB’s but would like a complete controller board.
I understand that you do not sell a complete kit. Is there a reference or article/website that would help me understand what I need to order and do in order to construct a functional unit? I have built a K2/100 but would need some guidance on the approach and details of assembling such a unit as well as modifying the software.
Hi Gary, exactly, it is not a full kit, I can help you build the parts that I described on the website, but you need an Arduino Nano module and load firmware. Soldering and assembling all mechanical parts are required (not SMD). Soon I will upload more information on how to build your own amplifier to the website, I have a lot of fun but it takes all my free time. 73 KM3KM
I look forward to seeing the additional information
I seriously love your blog.. Excellent colors & theme.
Did you create this site yourself? Please reply back as I’m
trying to create my own personal website and would like to find
out where you got this from or exactly what the theme is
Keep up the good work!
Hi Emanuel, I myself have created everything, if you need help I can share links and videos with you about it, thanks
Hello Kenny. Nice Amp kit design. Have been following this for a while. Would appreciate it if you could send me info on the loaded / tested boards you supply as well as info on what other items I need. Are you using the W6PQL RF deck that uses the NXP BLF188XR? I watched the video of Carlos in Costa Rica. He commented the amp is SWR sensitive? I thought the NXP transistor was massively swr insensitive? Is there any issue using this amp with an auto tuner like the MFJ998? I have a SB200 that I did a Utube rebuild vid on about ten years ago. Works great but your amp kit integration looks awesome.

Hi Ralph, good question! I currently use the LDMOS MRF1K50H device. Yes, the LDMOS devices are very robust, they survive very high SWRs, but other components are not designed for this. The capacitors can explode and the toroidal cores will heat up to lose their native properties. Previously, the controller was configured to stop the amplifier when SWR> 2.0, that is, at 1200 watts there is a reflected power of 133 watts. Now change the protection concept for Mismatch antenna,now the controller constantly evaluates the reflected power, if it is> 125 watts REF Power the amplifier stops quickly. Therefore you can work antennas with SWR> 2.0 and work less power. Remember, if the antenna is in bad condition the SWR trips for a few milliseconds and will activate the protection, this can happen in any solid state amplifier with protections. Yes, you can use a tuner, but I recommend you; If you have antennas with SWR> 1.5 try to start with the antenna and then the amplifier, believe me you will have better results))). Thanks for being here .
Thanks Kenny, Makes complete sense. I have my antenna pretty well tuned and plotted. Both are impressive devices. I spent 25 yrs in the semi biz. The NXP MRF 1K50H is also a beast of a part. NXP has committed to a minimum availability of 15 years for the device.That is a life time in the semi biz. I am interested in building one of these so please email me what you can. TNX RG
Ralph, It takes a long time to manually build these modules. I have taken many weekends and free time for this project. I am building some Controller that will be available directly store of the page, many hams ask me for the controller. Then I will take a 2 month break, do you want to wait? .You can buy the W6PQL power unit and Low Pass Filter, I am sure they are very good, you can adapt the KM3KM Controller with W6PQL modules. Thank you
Kenny, I am in no rush. Have been contemplating a solid state amp for years. What’s a few more months. Your design is awesome.
Sounds like you need a pick and place machine, an IR reflow oven and 48 hour days.
Please put me in the cue for a set of boards when you are going to start the next build.
Let me know. Thanks for your effort.
