We will be on the band at sunset to George, AA7JV Is this correct?: Baker Island time is UTC-12, so at local sunset on June 27, it is already June 28, UTC. On the USA west coast, it is very late on June 27. Are the dates on the web site in terms of Baker Island local time/date? BTW, are you sure you have to wait until sunset?

Topband: Baker Island DXpedition on 160
Hello TopBanders, KH1/KH7Z will be active on 160 from Baker Island from June 27 to July 6 (note that dates are tentative and may change -- please visit http://baker2018.net/ for updates). Given the time of the year, KH1 is likely to be challenging for most. In addition to the less then perfect time of the year, we are limited to a maximum antenna height of 43 feet. But, we do have a new antenna for 160 meters we will stand it in the salt-water to maximize its performance. We will also have a couple of DHDL receiving antennas with high performance pre-amplifiers. In other words, we will do our absolute best to overcome the handicaps that we were dealt. Our TX frequency will be 1822.5 to being with and we will be listening up. NA stations should call above 1825.0 to avoid the stronger JA callers, who are limited to below 1825.0 Our sunset will be at 07:45 UTC. We will be on the band at sunset to fully take advantage of the 1 1/2 hours of common darkness with the NA East Coast. During that time the sun will be still up in Japan, so we will be able to focus on NA and SA. West coast stations will have more than 4 hours of common darkness with us, they should have a decent chance of putting KH1 in the log. After the West Coast sunrise, from about 12:45 UTC onward, JA, UA0 and SE Asia, as well as ZL/VK, will have an exclusive shot at us. During this time we may move down to give the JA-s more room. EU will be,,,well ...difficult. We will stay on the air throughout each sunrise, working as far west as possible. GL and CU, George, AA7JV PS: Donations are the life-blood of DXpeditions and this one is no exception. _ Topband Reflector Archives - http://www.contesting.com/_topband
Topband: Summer Stew Perry Topband Challenge - this weekend
A final reminder that the summer Stew Perry contest is happening this weekend. After being silent in March, I am hoping to get K7RAT back on the air in time to hand out some QSOs. Will likely be a tree supported wire of some kind at the new QTH. Rules and previous results are here: http://www.kkn.net/stew Remember the brand new Stew Perry Quatre Seasons Award!! This special award - which will likely consist of a plaque - will be presented to the single-op participant who accumulates the highest total of points over the four events for a given year. This is the second event for 2018 - so you can add to your score from March. Your points will be counted regardless of which power category you enter. Note that the low power entry has a 1.5X multiplier and the QRP one has a 3X multiplier. You figure out which category will help your overall total at the end of the year.

Re: Topband: cutting coax stubs for 80 meter 4-square
Maybe my "Zoom" model is different from yours but I opened up my AA-55 Zoom and found the connector to be rather securely mounted. So much so that I reconsidered my idea of replacing the SO239 with a type N. Not that it isn't doable, just that it was more trouble than I wanted to bother with at the time.

I am thinking that RE realizes they have a weak mechanical mounting, relying on solder. I think I will revise my advice: 1. Always use a DC block 2. Carefully attach a short flexible coax jumper and leave in place. Calibrate it out. Then connect the DUT to the end of the jumper. No mechanical stress on the UHF.
