Unexpected Frequency Offset with Filter
Dr Thomas A Clark
At Dayton I got an INRAD 500 Hz CW filter to tighten up the passband
for PSK31 use. Here I am using the Menu #26 DIG=PSK31-U mode, so the filter is enabled with #38 FILTER=CW. What I see happen is that when the filter is enabled with NAR, the frequency jumps 30 Hz higher. I have checked and there is no on/off frequency shift in CW or sideband (with #38 set to SSB). Since these filters are passive devices, and since no offset is seen in SSB or CW, this seems to me to be a bug. With PSK31 bandwidths being so narrow, it is a pretty serious flaw. Has anyone else seen this problem? Or, by chance, is there a chance that this apparent bug is in fact an "unadvertised feature" (following the proud tradition of Windoze software)? 73 de Tom, W3IWI (private replies to w3iwi @ amsat.org) |

Loops
Mike Agner
I have been reading about loops in various antenna handbooks.
Not only are they useful at HF, VHF and UHF ops can use them very effectivly (unfortunatly my balcony is too small for a 20 meter loop, and it has a metal screened door...drat!)...

never been able to work a single station yet using the '817 without having the MP-1 sticking out the window and good grounding. Out of four hotel stops, my only success was with a sixth floor ledge in Cannes with a most convenient small copper water pipe running along the ledge onto which I could clamp. I did have a view of the ocean 10 blocks away but was next to a busy highway. Worked 19 countries in nearly as many QSO's down to 2.5 w on both phone and cw on 10 and 15m, even getting some 59 reports and a 20-minute solid copy ragchew on 10m SSB with Israel. I work in an office in Tokyo on the 32nd floor of a building with a great view looking north but have a window which doesn't open and I suspect is heavily leaded. I run a packet station on UHF and can connect with digipeters 50km away, but HF is worthless as there's no way to ground anything. I've tried all sorts of configurations inside the office next to the window with the MP-1, ATX, etc. Any suggestions would be greatly appreciated on how to devise something that might work here at the hi-rise QTH. 73, Steven K7USJ 7J1AIL -----Original Message-----

research on the subject locate the 1985 book by Ted Hart, W5QTR or the June/1986 issue of QST. In addition to it's small size, the extremely hi Q (approximately 500) provides fantastic front end selectivity and adjacent frequency strong signal rejection. The overall noise floor is about 1/4th that of a vertical. In March I published a product review for Wayne Green Publication on the MFJ 1786 loop antenna. Aside of it's somewhat high price, it is a very very good antenna. If you decide to build your own, you will need to very mechanical inclined with allot of metal working shop tools. ----- Original Message -----

Repeater Offset shows both -+ ??
Can't figure out what's going on as I have one memory channel for a
local repeater that was originally set with - offset now showing offset as both -+. The transmit is still on the - but the icon shows both -+. Other repeater offsets set in memory have not changed and show either - or +. When I punch the A button under RPT nothing happens on this channel...works ok on other memory channels. Second strange thing (or maybe I haven't been paying attention!) other than using RIT my VFO will only register 20hz changes in display when tuning...with the RIT it will register to the 10hz. OK, have I gone batty? Is it time I took a holiday from this little rig? 73 Lynn Hilborn VE3CSS |

I don't know about everyone else saying they were quoted a price of $669 USD at HRO. When I checked on Friday AM HRO was selling them for $639 UDS each!? So I got one, paid cash, and my printed sales slip shows the price I was quoted above. Maybe they were selling so fast they jacked the price up to match the vendor in the next booth, which was quoting a price of $669 USD each, later on. Hummm? The highest price I was quoted was $760 USD from Michigan Radio. When I said I could get one from HRO much cheaper I was told, by a sales agent at the vendor's booth, that they were "selling old stock, and not the model with the current factory changes". I checked at the Yaesu booth and was told that was completely untrue. Looks like Dayton's Hamvention is not the place for the careless shopper if they want to save money. 8->> Leland C.

USER REPORT: DX, ANTENNAS (MP-1), ETC!!! Long Post...
I have been using my FT817 for several weeks and wanted to post some
feedback to the group, especially with regard to my field trials of the MP-1 antenna, etc. My goal with the 817 is two fold: a QRP WAS and a QRP WAC, so my comments and evaluation will come from that perspective. This past weekend from my QTH in the SF Bay area I was able to work the following states and DX: S.C*, AZ*, TX*, CO*, ME, OH, WA*, AR, VK2*, VK3*, VK4*, ZL1, VE6, and VE7* (* multiple QSO's). I was using either my MP-1 set up in my backyard or a multi band shortened 40-10M dipole mounted at 10' AGL. ALL CONTACTS VIA SSB. I worked 40 / 20 and 15M. Working a VK from my QTH is total of 7,845 miles, or 1500+ miles per watt. (***I just missed a ZF--he couldn't get my call correct so he didn't go down in the log...next time.) I worked the ZL1 and the Maine QSO on the same night! In all cases the 10' high dipole greatly out performed the MP-1 regardless of band. I even tried the cardboard box trick that Vern suggested to reduce hard coupling with the ground. I was using a Z-11 tuner, however I was able to get a "no bar" SWR intication from the 817 by carefully hand tuning the loading coil with out the Z-11 on all bands I worked. Signal reports were generally +S3 better with the dipole even at only 10'. Feedback about the 817 was very consistent: Great audio. R/S reports ranged from 5 /1 to 5 /9++. My recommendation for phone mode is to be very aware of the mic. gain levels..I needed to run at a setting of "70" to get good deflection on the PWR meter on the 817. I received no reports of flat topping or over mod. on my audio with this setting, however. I made all my DX QSO's responding to CQ's or "tail ending" and logged a total of 6 VK's that I contacted in one call to their CQ in about 90 min. Bagging DX on one call running QRP is absolutely thrilling. Without exception Hams have been very supportive of my QRP efforts and more than once I received a call from others eager to really see if I was just running 5 watts. BTW..The VK guys love to work a QRP QSO. I plan to conduct a similar side by side test this weekend in preperation for gettting my field day set up finalized. Right now the dipole is looking real good. I have also been doing extensive testing of Mark Smith's RATS CAT GUI. I like this application a lot, more on RATS on another post. ( have no financial affiliation with Kingsmith software, etc., etc...). Like to hear about similar DX / WAS success from others. Thanks in advance. :harry |
