Topband: sunrise peak

Hi I have never yet observed a sunrise peak from HS0ZIA. In fact the band usually goes completely dead here to EU (to my NW) about an hour before my local SR.  73 Bob _ Topband Reflector Archives - http://www.contesting.com/_topband

Re: Topband: VU2GSM webSDR use

Thanks for posting this Steve - much that has been puzzling me is now clear. Remote SDRs, bizarre DXCC "entities", lists, skeds, FT8 etc are why I stopped pursuing awards a long long time ago. But to each his merry own...73 On Sunday, January 14, 2018, 11:00:15 PM GMT+7, Steve Babcock

Topband: HS0ZIA

Hi HS0ZIA is now CL until May. I logged 294 unique calls in the last 6 weeks of part time activity (I do not live at the station) on 160m outside of any contest activity and those who seem to want another QSO every day, mostly in EU and AS. I spent most of the SP test listening for the big

Re: Topband: FT8 - the end of 160m old school DXing? (long)

Agree completely Steve. I was going to build a 2m EME station until I learned that computer to computer Qs were the only thing going on there these daysnot for me.  73 Bob HS0ZIA From: Steve Ireland To: Topband reflector Sent:

Topband: Top-Beam Systems

Hi does anyone know if Top-Beam Systems is still a going concern? I placed and paid for an order over 6 months ago and the company has not responded to my email inquiring about the status of my order. Thanks 73 Bob HS0ZIA _ Topband Reflector Archives -

Re: Topband: 160 4 square

Well I ordered one about half a year ago so if it ever comes I will be able to compare it directly with my HiZ 8 circle array and get a definitive answer. We have no local noise here only propagated tropical QRN. 73 Bob HS0ZIA Sent from Yahoo Mail on Android On Mon, Aug 28, 2017 at 18:56,

Re: Topband: Relocation to mountainous area

Hi Mark Put down as many non resonant ground or elevated radials as you can. You can do nothing about the far field pseudo Brewster angle. The Hi Z manual states the recommended deviation in element elevation but I suspect it will work OK. 73  GL Sent from Yahoo Mail on Android On Sun, Aug

Topband: tower vertical

Hi I have decided to put up a 40m tower to use as a transmitting vertical for 1.8mHz out away from in between our other towers and where I can run 1/4 wave radials all the way around, and will probably use locally available 12" steel sections with a conical-type pin base. I would like to

Re: Topband: 60' or 70' spacing on Hi-Z 4/8 element RX array

Hi Gary We plan to set up ours with 60' spacing for best 40m performance, and with just 10' elements.. When it is done we will be able to compare the performance on 80 and 160 with our monoband 8 circles. I agree that power gain is not important, particularly in our high QRN environment. AFAIK

Topband: IC7300 Hack

Hi guys the Thai NBTC has allowed a special factory version of the IC 7300 with 6m tx disabled to be legalized for use in HS (the first modern radio in decades) but I just discovered that this version also has the bottom 10 kHz of 160 disabled tx as well per EU I guess. Anyone know if it is

Topband: HiZ 8 circle array 1st impression

Hi we finally got our HiZ 80 and 160m arrays up and running and the performance appears to be as advertised. We used 6m guyed steel tubes mounted on PVC insulators for the 160m elements and 3m wires inside PVC for the concentric 80m array. Each element has a 1m copper clad ground rod in good

Topband: safely sharing an RX antenna

Hi I was thinking about using a 3dB splitter and tuning the band with our second K3 using our HiZ monoband 8 circle while we were calling CQ in the Stew. The center of the array is located 105 meters from the xmit vertical, uses 20' elements, the included preamp and 100m of RG6 transmission

Re: Topband: Why do rodents eat coax?

Hi Dave I am currently rebuilding the RX antennas after rodents chewed meter-long sections of flooded RG6 away to the center wire before it was even operational. Now putting all the cables into PVC pipe laying on top of the ground -  over 300 meters of flanged pipe sliding over the cables one

Topband: vertical balun

Hi we have a 30m top loaded monopole with the feed point about 2m above a large ground radial field. Right now we are feeding it through a 4:1 balun (not a unun) with 12.5 ohms on the balanced side, and the SWR is 1.4 with no matching network. Is this balun acting as a common mode choke? Do we

Topband: Snap and seal F connectors

Hi unfortunately our rx array was destroyed by rodents chewing away the RG6 cable so It's going to need rebuilding with PVC conduit. Does anyone know if snap and seal F connectors can be re-used? TIA Bob HS0ZIA _ Topband Reflector Archives - http://www.contesting.com/_topband

Topband: 9 kHz heterodyne BCI

Hi we just got QRV on 160 right before the SP and noticed AM BCI at 1800 kHz and every 9 kHZ  up from there. Since 9 kHz is the BC channel spacing here I suspect two adjacent stations are mixing. Somehow somewhere. Maybe here in my station, one of the BC stations or somewhere else?

Re: Topband: Rig Question

Well I have one of the earlier K3s ~#1000, that was never modified, never had a software upgrade and got quite a few unsolicited reports of good audio, the few times I ever went on SSB outside a contest. Using the Heil headset they sell with it. It's finally gone back to the factory since for
