Good evening.I wonder if anyone can tell me what is acceptable phase error in 432mhz phaselines.The sky is the limit of course but what percentage of difference is good or qualified as very good.
I have cut following sofar (to my reference phase line).0116%.1616%.5477%
The .5% seems too big error to me.The 0.0116% looks to be very good to me.Its just 50khz difference with my 432.100mhz line.
Any thoughts?

I am happy to announce that 06/05/17 at 2142 utc we have been able to
make the first 3cm EME QSO between two SA stations.

Hello All,
Can anybody help or inform me on how to order a pair of these encoders?
Are they still available?
I get zero response from the manufacturier. Made several efforts to contact.

Sri guys,
I overlooked the word feed being still concerned on the whole path from the previous emails.
Excuse me , pls !

Hi Ingolf,
just in short.
Cross-polarization discrimination (we used term XPD in the DUBUS 3&4/2014) on the bounced 3cm signal does show about 6dB on CP and about 11dB on LP when we suppose that the whole Moon's disk is illuminated.That is obvious case for dishes small than about 4m.
It does mean that about -6.5dB and/or -10.5dB of incident power is lost in cross-polarisation, i.e. in opposite sense of CP or in cross-polarized LP signal. That respond to a loss of about 1.1dB at CP and about 0.4dB at LP.
The difference of about 1.1 - 0.4 = 0.7 dB is what you have asked for.
It is the maximum benefit of LP over CP when you can fully compensate the mutual spatial off-set, i.e. rotate polarisation on one of the both ends (stations).
Hope it helps.

Hi Peter.How much additional loss do you estimate there to be in an 10 GHz CP feed compared to a LP feed?In your opinion, what is the reason for this additional loss?73 / Ingolf, SM6FHZ

Hi Vlada I found the conditions quite good I had roaring echo during the weekend.
I have also given the CP/LIN some thoughts and I get by using V pol and twist in case of need. Problem is no one get their CP Feeds near the performance of Lin feeds. There are additional losses in the CP feeds. Furthermore when one design a feed it is almost not fitting 100% illumination wise. Specially in Offset dishes that can be felt. Also dimensions are quite critical on 3cm making a good Circular Feed.
I would need a waveguide Feed for Andrew/channelmaster dish.
I am sure it will be hard to get all to agree on the topic.
Agreed power is insane at JLW and at my Station. Well my TWTA is a Class A TWT and does like making max power out in the feed. Otherwise it is just dissipated in the TWT. It draws 3000W from the 230V when PTT. It delives around 750W on the flange but big loss in feeder system.
Why alligator power ???. Well it makes everybody able to hear a signal from the moon same as the Beacon but only better as there Is actually a person behind.
I try to infect as many as possible to this challenging part of our hobby. Hearing a signal from the moon makes them want more.
Even my own kids are very amazed when I let them say a few words and hear them back from the Moon :o).
Vlada it is stations like you that makes the band a success as it is always possible to work you.
By the way soon I be QROO on 5.7Ghz also I just got the Waveguide feeder so will make 500W where around 300W will hit my Feed horn that actually is CP :O)
Have a nice day both of you.

Hi Dominique,
first sincere congrats to 1st CW 3cm QSO.
However something still to think about as the both OZ1LPR and SP6JLW have huge TX power.
Have you ever found ours 50W signal during the contest ?
FYI, we made 32 CW QSOs.
E.g. we made also random CW QSO with OK2AQ with 1.2m dish and similar power (close to 50W at max) at spread of 120Hz, but with linear polarisation !
Seems, these 3dB is terrible difference in real ether !
Probably, we shall live with LP vs CP troubles for some years and for many it is not as easy to swap it.

Hello All
Yesterday I wkd my 1st. 3cm EME QSO withOZ1LPR. It took almost 45 minutes to complete due to my small signal. Later I had another chance with SP6JLW, - same proceedure taking 30 minutes.. Easy copy at HB9BBD.No chatroom arrangement or internet stuff, real EME in CW.Thank you guys for this great fun!
Rig at HB9BBD: 1M offset dish, CIRCULAR POL, 50W, home made LNA 0.65dB NF.

Gary N8CQ's standalone tracking system uses a small touchscreen display and doesn't require a PC. Works with a variety of encoders. Inquire with him via email.

Slawek,
I've been reading the e-mail recently of digital encoders. I am
thinking to install two pair for both 2m and 6m eme arrays and cost of
the HH-12 is very much better. I wonder what az-el pc boards are
used or usable with the HH-12? Trying to keep costs down for this
but want to have auto-tracking sw compatibility.
Would be nice to have LCD angle display separate from computer display
for manual tracking.
Currently using Ham rotators with 5 degree resolution analog displays
which are not eme friendly and use linear actuators for elevation which
take using a comparison chart for angle. Digital encoders much
better way to do this.

Hello Rein,
I have talked to my friend Georg yet. He is a non english speaker and in

He is a retired ham and not a company.
Anyway: I can help you. 2 encoders including postage to USA are 72 Euro
total. Additional encoder is for 29 Euro possible.
If you like to buy contact me directly please. We can do a transfer via
paypal. I will not have any money on that action, but manage money and
translation for DF1SR.
I am using those encoders on my 8m dish with big succes.

This weekend I fitted my new feed, SM6FHZ design for my 2.4m offset, together with an improved modified LNB. After more adjustment of feed position I now get 12.75dB sun noise SF74 and moon noise 1.2dB and CS/ Ground 4.4dB. I copied the following stations over the weekend. PA0BAT, SP6JLW, HB9Q, ES5PC, OF2DG, HB9BHU, OK1KIR, OZ1LPR, IK2RTI, OK1CA, DL7YC, YO2BCT, DL0EF and VE4MA and I could see OK1DFC on JT. I’m quite pleased with that result and I now believe I have a working antenna system and will press on with the tracking and Tx side of the system.
