Re: [Elecraft] KX3 booster

Petr, The KXPA100 was designed specifically for this purpose. It is rugged, high performance, fully integrated with the KX3, and very reliable. With PIN diode T/R switching and a fanless design (very large heat sink), it's like having a 100 watt KX3. Also makes a great mobile amp, with

Re: [Elecraft] KX3 booster

Gordon, many thanks. I know about it but it is 50W only. (at the best) I am looking for something to give full standard 100W out as same as other barefoot transceivers. So idea was to have in portable QTH my KX3 reduced to clean 5W out boosted to 100W out which is corresponding to conservative

Re: [Elecraft] KX3 booster

I have found the HardRock 50 amp/tuner kit to be great.  I have used it with a K2 and Apache Labs ANAN-10e, both QRP rigs. See: It is a kit, but relatively easy to build, especially compared to a K2, or even a K1. Gordon -

Re: [Elecraft] KX3 booster

Jim, thanks for info. In fact I spurned the RM Italy for the same reason. Maybe the solution is here: http://www.jumaradio.com/juma-pa100/ ...but Juma has not the kit in stock for long time. Also the price is a bit above the budget. - 73 - Petr, OK1RP "Apple & Elecraft freak"

Re: [Elecraft] KX3 booster

The model that DXE is selling is a VHF amp.  Note the disclaimer for the HF model -  RM Italy KL 405v HF Linear Amplifier with Fan "Export Only: This Model is not for sale in US, we only ship to the address outside of US." Needless to say, I would not run my call through one of these amps.

Re: [Elecraft] KX3 booster

About 5 years ago I had been using HLA300 with my KX3/ RF VOX was disabled and PTT circuit was modified. Some LPF were available in HLA300 then. It worked OK until final transistors died. Could not find identical substitute and had to resort to different transistors which resulted in less

Hi all, I would like to ask if someone is tested or even using some 100W-150W non-Elecraft booster for KX3? I am looking for something cheap but reliable and found this small toy: http://www.rmitaly.us/index.php?main_page=product_info_id=128 The big disadvantage is that T/R switching is RF VOX
