Re: Topband: your opinion about ICE RF limiter

I have used one for many years and it saved the front end of a TS 830s when an elevated radial drooped and touched a beverage antenna. I have used it on my FT1000mp since 1993 with no failures or additional noise noticed. Well worth the money and the piece of mind it brings Dan W8CAR

I use one between my K3 and 160 meter flag antenna for receive. No attenuation at all in received signal and no worries now about too much RF getting back into the K3 from the receive ant line. I second what Dan, W8CAR said. Peace of mind, (small insurance to pay to protect your expensive HF

Felipe, maybe you will have problems buying at ICE right now. I use to have KD9SV products and I am very happy with them. Front end saver http://www.radio-ware.com/products/fes.htm 73, Jorge CX6VM/CW5W -Mensaje original- De: towertalk-boun...@contesting.com

When saturated - it does cause broadband diode noise. http://www.iceradioproducts.com/reconly.html And the text says: Circuit uses a multi-stage design of transformer saturation coupling and current limiters. The best I can get out of this is that when the transformers saturate,

Have you studied what IARU says about the 160 m bandplan? To summarize: SSB is allowed all over the place! We can never expect ITU or even the national authorities to take action in order to divide this band into segments. With the present statements from IARU any narrow band mode is allowed

Woke up about 6:00 a.m. California time, stumble to the rig, and was very pleased to hear lots of strong signals out of Asia and Russia ... Du1, RU0, JA, 9M6, etc. The signals were from S1 to S9. Some I thought were Stateside until I heard their call sign. The 160 season is not over yet. In

Here some info on loading coils and current distribution in loaded resonant antennas. http://www.k3bu.us/loadingcoils.htm In the nutshell: efficiency is roughly proportional to the area under the current curve along the radiator. It is better to have loading coil or top loading than distributed
