K3 QRPp
Locked
 
|
assuming a k3 and it is fully loaded;
If I want to operate at say, 1 watt I believe all I have to do is adjust the power out and it will go from 100mw to 120W using the main antenna 1 or 2. If that is true, how does one select and use less that that? If one uses the BNC out on the transverter board KXV3, how does one select this and also adjust the power out & receiving antenna?

Set up the transverter band per page 39 in the manual (latest rev D-2). Use the XVTR OUT connector for the Tx output. Be sure to run the transmit calibrations routine from the K3 Utility for the milliwatt output. See the help in K3 Utility for details. If you want to force the radio to use milliwatt level output on the KXV3 without first setting up a transverter band, then set CONFIG:KXV3 TEST.

In reply to this post by KK7P
Lyle & Dave,
Thank you so much for your explanations. I realize all the efforts I have put in towards my 150 meter radial field had to work in my favor. I am on the ocean and my back yard is a salt water marsh. I use the first tall tree at the marsh's edge as the support for my 160 meter inverted-L. It is electrically long and I use doorknobs at the feed point to give me a 1:1 match at 1.830. I have 60 some 130' radials laid out with 1/2 of them on the marsh and the rest on the bog beside it. I have the same kind of L attached to the radial plate for 80M and in the center of the plate is attached a butternut HF9V. The get selected via an Ameritron remote coax switch. FWIW, I do extremely well on low bands with this for I'm forever hearing in contests how powerful my signal is yet I always adhere to less than 1500W out. CW I set at around 1,100 watts out in a contest just so I know my score is guaranteed to be legit. Several days ago I worked at the K3 stated 100mw level and was amazed by how many replies I was able to get on 160M & 80M. I had started out at 5W and gotten several replies and then when I received a 579 from Wisconsin on 160, I dropped to the lowest the scale offered at 100mw and he gave me a 459. I called more CQs at 100mw and worked a NC, IA and MI back to back, to back. I wanted to go lower and try 10mw, even 1mw if possible but was not sure how to do this without possibly transmitting into the wrong output. I am on the road at the moment but will try your suggestions when I get back. Amazing what an advantageous antenna system will do. I entered the SSB contest for two hours last night just to give people some contacts/multipliers. The C6 I worked said he'd heard me earlier and took the time to tell me several sentences worth how powerful my signal was. The same for several VE stations and one from WV. I know the antenna is big in those reports but I also wonder how much using the K3 with it's compression played a part as well?

Propagation was pretty darn good too...
worked a Mn station running 5 watts who was 30 over in Tn. Folks were telling me I was pegging the needle running 100 watts. Really wasn't expecting those lind of comments, nor the DX worked either. QRP is surprisingly effective on 160 with a decent antenna, and sometimes without... 72, Julius n2wn

Hi Julius
What is your decent antenna, may I ask? Do you use rx antennas too?

Hi David,
I have a combo Tee. It has about 72' of vertical aluminum (2.5" tapering to 1.5") with a two wire sloping tophat. They slope down about 10 to 15 degrees, uneven to the nearest tall trees. The base of the antenna is about 10' away from the corner of the house and maybe 20 from the operating desk... I do have a short beverage. It's 330' long made from coax, meant to be bi-directional, but on seems to work towards EU. I don't use it a lot as my QTH is reasonably quiet. It does help in contests and in noise. Rx antenna(s) is probably my weak spot, can't put up a longer beverage, and recently the neighbors calves have found the wires on the beverage ummm tasty :o( I have plans for a new antenna using an AB-621 as the base for a slightly taller (82') and thicker (6" tapering to 3") vertical section. I have a lot of radials, ranging from 10' to 120', with most being around 40 to 60' long.

For anyone considering trying QRP(p) operation, don't be put off by
tales of super antennas. Yes, a good antenna always helps, and if you have an unusually good setup, by all means take advantage of it. But surprising results can be had with strictly average setups. This weekend, I achieved a new personal best miles-per-watt record (Oregon to Ohio, about 21510 miles/watt) with my K3 on 30m at 100mW using my Butternut HF6V antenna (ground mounted with 16 short radials.) I know that's nowhere near any real records, but for casual QRP-ing that involved nothing more than turning the power knob down, it was a kick. 73 -- Joe KB8AP On Mar 2, 2009, at 6:59 AM, Julius Fazekas n2wn wrote: > > Propagation was pretty darn good too... > > worked a Mn station running 5 watts who was 30 over in Tn. > > Folks were telling me I was pegging the needle running 100 watts. > Really > wasn't expecting those lind of comments, nor the DX worked either. > > QRP is surprisingly effective on 160 with a decent antenna, and > sometimes > without... > > 72, > Julius > n2wn > Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |
