With 3 kW and 22 element log periodic up 50 feet which itself was up 50 feet over salt water, your problem was HEARING the other station.
Tell us what difficult DX you worked with it? KPH on 4 MHz at noon?

No the LPA was about 25 feet above the flying bridge. The BOOM was 50 feet long. It had a frequency range of 6 to 30 MHz. As with all LP’s the higher in frequency you use it the better the gain of the antenna. We had problems with getting it on 6 MHz as far as SWR goes. So we made up a 6 MHz dipole inverted V and hung it from under the radar mast at the apex. These LP antennas are the same as KHT used in Cedar Rapids, Iowa and was said to be around $12K each. KHT used the SAC Air Force base in Cedar Rapids with government agreement to keep the Collins HF gear operational. They had another antenna farm in Newport Beach, CA that they could remote to if need be. All of the antennas were LPA, the same one we used. If I remember correctly I think there were 4 or 5 separate LPA’s at Newport Beach on separate towers.
As far as difficulty hearing stations was no problem. Night communications were mostly on 8 or 6 MHz to SFO. While on station during daytime communications 12 or 16 MHz were used for SFO.
We had a Pacific navigation chart with a rose on it in the radio room. When we were going to use the LP we would call the bridge and get our heading, then transpose the heading to point the LP to SFO. Never a problem.
Just a side note, we were told we would be on our own if things went awry and the USS Midway aircraft carrier would be our back up. We found out that the Midway was in Yokosuka, Japan. The Midway was the ship I was on in the Navy…..go figure. We were on our own!

Fill me in Eric, did you see the transmitters and LP antennas?
Dick
Eric – I am not questing your input but I am curious as to what they were using for transmitters? Thanks

Hi Joel,
Yes we were advised of the possible contact with the Chazhma/UMGT. After they made radar contact with us and came close to our ship, I had the LP turned to Pearl Harbor and all the transmitters up and on standby. I had called them on 500, 2182, 8 MHz and no answers to any of my calls. This went on for some time and I wanted Pearl Harbor to know they had made visual contact with us. Finally my last call to the Chazhma I asked if blinking light would be okay. The Third Mate made contact with the light and that is when we set up the 2182 QSO. I had my partner awaken to come into the radio room and briefed him what was going on. I had to go up to the forward navigation house to get on 2182. We kept all the 2182 equipment up there since it would not be used that often. We did have SSB equipment back in the after house if needed. The lowest frequency we had programed was 4 MHz, so that is why I had to go forward for the 2182 QSO.
I was the only one to make contact via radio with the Chazhma/UMGT and needless to say it was a very precarious time. For we didn’t know what their intensions were. I have a copy of the communications but it is very difficult to understand. For one they had very bad modulation and very deep base audio. Our Navy Captain was really upset with them at the time and had to be calmed down. After all he was a nuke submarine Captain. I have pictures of the Chazhma and the later support SB-10 boat. It was believed the SB-10 was a supply/repair boat for their submarines.
Yes I have been on many merchant vessels when the mate would call up to help them read blinking light from another ship, mostly a Navy ship.
I have had that unclassified report for some time now. It is pretty good and of course there are other things that is not in there but that is understandable.
I was told a long time ago that the SSB station KHT in Cedar Rapids, Iowa was contracted as a limited communications station manly to keep the USAF SAC HF equipment operational. I do not know where the SAC base is but we have used it quite frequently when I sailed for Exxon. Even for a limited station to have all the LPA antennas and towers in Newport Beach for remoting to is a stretch as far as cost. Do you have any information as to why KMI was a limited communication station?

Thanks for the info Eric, maybe someone who maybe worked there could fill us in.
Thanks

Hey David – that is my mistake. It should have been KHT not KMI. Yes they would run phone patches to our office when I was with Exxon. I know Global Marine used them as well. I used to hear the drill ships in the Gulf of Mexico sending in their progress reports using KHT. I don’t remember who or where I heard that they were a limited coast station and that they were contracted basically to keep the HF Collins gear operational for the USAF SAC Bases. When I made the transit around the Magellan Straits on an Exxon ship we still could raise them for communications. This was in the late 70’s. I will see if I can get more information on the subject.

Yes Joel – there were as far as I can remember 3 or 4 vans below decks next to the control room that the various spooks were located. The CIA was in constant contact with the White House at the time during the mission. So I am sure the Navy spooks copied the message from Pearl.
The intel groups used satellite for their coms. Yes there were satellite communications in those days 1974.

Suit yourself OM – but I talked to the Iron Boot and I have in writing as such. Maybe next time OM I will get your approval first.
