I recently furnished my station with old Yaesu Musen FT-707 HF transceiver and starting to explore the HF bands. I have only a very elementary question and I think for those experienced hams they can help me out. my question is : What is ALC or Automatic Level Control? How it works? Please help. I apologize for my ignorance.

What would be the best antenna for Local work and for DX work, Horizontal Dipole or Inverted Vee? Why?

Any further info about Comet CWA 1000 3.5/7/14/21/28MHz Trapped Dipole? Is this a good wire antenna? Any experienced hams already used the Comet CWA 1000 3.5/7/14/21/28MHz Trapped Dipole? Any advice. Many thanks and Happy Holidays to All!

To KB1LKR,

Hi!

I haven't tried to phone them but I already sent an email iquiry regarding B & W model 430 HF Broadband "no-tune" antenna. Anyway, many thanks oldman for the advice, 73.

To W5CPT,

Hi!

I would like to see it. Please send me a copy to my email: dw1uby@gmail.com .

Excited to see it.

Many thanks.

Many thanks for the wonderful advice. I almost brought myself to that store in Raon, City of Manila and buy Diamond HF Broadband "No-tune" Folded Dipole. I don't like HF verticals since I used it to my CB radio then. I don't like the performance. I used a Lazy H before for my CB radio. Now from 2-meter operation now I migrated to HF (now my call is DW1UBY). Anyway, going back to B & W model 430, yes the old man told me he "can make me an exact replica of B & W model 430 HF broadband (multiband) "no-tune" wire antenna". According to him, he has the exact antenna specifications/dimensions etc. in order to construct that "mystery antenna". Some old hams in my locality told me that B & W model 430 was a post-World War II era military antenna used by the American Military (I don't know.... I doubt it!). Right now I'm still using my Yaesu FT-707 HF transceiver with 35 feet of UTP wires connected to the positive (the center of SO-239) so that I can hear DX stations. Still I'm listening on the HF bands and feared of transmitting my old Yaesu Musen radio (because I am using a cheap 3A regulated power supply; it takes only 1.2A - 1.5A for receive.)Yet, I'm still lucky to have you and I respect your "rule of thumb" advice to me. I hope my barefoot signal will be heard soon if I got a 30-35A new regulated power supply, a modest tuner and a better antenna. HF really rocks! Best regards and 73.

I recently owned an old Yaesu FT-707 HF SSB/CW/AM transceiver and right now, I'm using wire strands of CAT 5e as an antenna. I used it for about 3 days from now and I would like to know an antenna something Greek to me. I cannot find this kind of antenna on the net. Here's my question: I would like to know if anyone here has an info regarding Barker Williamson model 430 HF antenna? What it looks like? Operating freq? What are the specifications? How long is it? Is there anyone can discuss further about this antenna?

Thank you for helping me. I found the radio expensive to me and it cost around Php4000.00, I want that old radio but what I have only Php1500.00. Right now I am using a 2nd hand Icom 02N HT, connected to a homebrew 6db vertical and used it as a base station radio. I don't want to sell this radio because this is my very first radio since I started in Amateur Radio. Right now, I'm practicing sending & receiving Morse Code through tapping my fingers in a old plywood and do the code. Also, I used to read old newspapers and try to decode every character in my head. I am glad I can copy at 8 WPM. I wish I can have that old radio so that I can enjoy HF, in phone or in cw modes. I really envy you Americans because you have everything. Again, many thanks for the info.

Guys,

Good day! Is there anyone from the group have an detailed info regarding URC-187 Tranceiver Set? Please tell me. Many thanks and best regards.

what ham antenna design for a 144 MhZ? Any designs from directional to omnidirectional antennas?
