I have all of my licenses, starting with a Novice in 1964.

Re: Topband: Preamplifiers
You might consider building a W7IUV preamp. It is a very easy to build boradband preamp that you can build using double sided circuit board in which you can easily cut in the pattern on one side of the circuit board using a Dremel tool, and the opposite side is the ground plane. I created a website to document my builds of this preamp, and here is my website URL in which I provide the artwork for the circuit board, along with parts placement. On my website I also provide a link to the W7IUV website where you can find the most current schematic. http://sites.google.com/site/rxpreamps/ This preamp can handle very strong input signals without being harmed. Gain approximately 20 to 22 dB. 73, Don (wd8dsb) On Mon, Feb 2, 2015 at 4:08 PM, Andy YO3JR andyru...@gmail.com wrote: Hi, Can someone recommend me a good preamplifier for the beverage antennas on 80/160m?

Re: Topband: Remote Operation
Hi, While I agree in principle I question whether the receiver and it's location have legal identification requirements. In the U.S.A. at least, receivers and their operators are NOT licensed. Transmitters and transmitter operation are. One guideline I saw suggested a remote receiver - located in a quiet area - should be in the same grid square as the associated transmitter. A rule like that is from a contest or certificate sponsor and not from a regulatory agency like our FCC. There have always been and will always be 'cheaters'. They know who they are. 73, Bill KU8H On 02/02/2015 12:07 AM, m.r. wrote: To me the remote operation ethics have always been clear, and still are. It makes absolutely NO difference where the operator is sitting. The contact is between the two physical stations. Any station - remotely controlled or not - must identify legally under the rules of the county in which the RF transmitter and receiver are located. This includes properly identifying the zone, state, section, grid square, whatever the current activity requires. When it is just the country, that must also be clear. In this case, if OE1AZS was using the W4ABC station, he could legally identify in two ways, Just W4ABC, or W4/OE1AZS. It is NOT legal for a transmitter in the W4 district of the US to be identified ONLY as OE1AZS. It does not matter if the person, OE1AZS, is sitting at the knobs at W4ABC, or is sitting at home controlling the W4ABC station by remote control. But, folks who can, will cheat just to be first in a log. They really only cheat themselves, to the DX station, its just one more contact Claming the contact for DXCC or any other kind of award credit is cheating.

Re: Topband: Remote Operation
Absolutly agree, It makes absolutely NO difference where the operator is sitting. The contact is between the two physical stations. I send same statement few days ago, and its VERY CLEAR, except someone deliberatly dont want to make it clear Callsign is assigned to HAM for Station, and Station have physical / geographic Location , Latitude/Longitude... if Op not operating from that location, then there is /p /m /mm /am etc, / ctry pfx if in other ctry, and its perfect system then only question remain is how far RX Antenna/ Antennas can be from TX , as we taking TX Location as Station location (is remote Acces by dedicated IP Link, public Interent, RF Link, make no diffrence at all...) All this is self understandable, so I think no need for any wide discussion, I just repeat my Opinoin 73 all dado E74AW -Original Message- From: Topband [mailto:topband-boun...@contesting.com] On Behalf Of m.r.

Z10043 used here. It's sold by Jack Smith K8ZOA who is an instrumentation and test engineer - which means all of his stuff is wrung out to the max. In the preamp business, there are a lot of loosely defined claims but with Jack's preamps, if you want a specific or special test performed on your unit (for example, trimmed for optimal NF) he can arrange it. 73/jeff/ac0c www.ac0c.com alpha-charlie-zero-charlie -Original Message- From: donov...@starpower.net Sent: Tuesday, February 03, 2015 9:10 AM To: topband Cc: andyru...@gmail.com Subject: Re: Topband: Preamplifiers Hi Andy , I use preamps from three different manufacturers in my station : - DX Engineering RPA-1 $143.95 - Clifton Labs Z10043 (or Z10042) Norton Preamp $100.00 (with enclosure) - Advanced Receiver Research P1-30/20VD $69.95 I use W3LPL bandpass filters in front of every preamp because of the extreme out-of-band signal levels in my multi-multi station.

Re: Topband: Remote Operation
Hi, I just pulled my last license (now expired) from the desk drawer and looked at it. It refers to my primary station and has the physical address. I'm pretty sure my current license will bear the same information. It's up for renewal and maybe the new one will be different. Other parts of the rules regulate our emitted signals and NOT our received signals. I have read and/or heard that in some other countries receivers were or are regulated. Therefore - YMMV. 73, Bill KU8H On 02/02/2015 10:18 AM, Tod wrote: US hams who were licensed in the 50's will remember that you got a separate Operator's license and Station license.
