From Dave G3YMC Just to remind you that Derek G3GRO will be giving his 136 talk at the Bracknell Club Wednesday 13th October, 8pm at Coopers Hill Centre, Crowthorne Rd. North, Bracknell. All are welc
Apologies for putting this on the reflector. I have had a request from Heinz OE5EEP for sourcing information on Philips 376 capacitors. Unfortunately all mails to his address ([email protected]) are get
From Dave G3YMC Many thanks for all of you who took the time to transmit for us on Wednesday evening during Derek G3GRO's talk at the Bracknell Club. In fact we were so engrossed listening to Derek t
From Dave G3YMC "Meinen Glueckwunsch! Es ist erstaunlich, aber ich liege offensichtlich in einer toten Zone um SM6PXJ. Ausser einigen Bruchstuecken habe ich noch nie etwas von ihm gehoert. Im Gegensa
From Dave G3YMC I agree with the comments of Rik and others that we should not be too restrictive on bandplanning, although accept that some form of planning is a good idea. With the use of specialis
From Dave G3YMC Many thanks for the information on CFH obtained from VE1FTL by Alan. Now at least we know a little more about it. As Jon says it seems off the air at the moment (it would now be quite
From Dave G3YMC <Some rambling...... <If the ERP from the VE on 137 is 20% of 10kW, that equals about 2kW ERP. <I can't remember what the best signal to noise is on the signal. Would 10dB <be about r
From Dave G3YMC A couple of corrections to Alan's recent mail We are told the height of the mast at CFH is 600 feet (not 200 ft). That is a bit a different. I do not have an accurate locator for CFH
From Dave G3YMC <From Peter Dodd, G3LDO <I hope to do some tests from GB2CPM tomorrow, Friday 28th and Sunday <31st of this month. I was listening on 136 all day Friday from 6.30 local and heard noth
From Dave G3YMC 1. Currently (Friday evening and Saturday) there is extremely bad thunder static on 136, worse that I would expect at this time of year, and this makes QSOs very difficult. Perhaps th
From Dave G3YMC For information I have used plastic electrical conduit, oval shaped and cheaply available in various sizes, as spacers for open wire feeder. I do not know how this plastic would cope
From Dave G3YMC The mails from Laurie and Rik on this subject are interesting. They show a reflection layer for sky wave at some 60-80km, with a first hop skip distance a little under 2000km. Perahps
From Dave G3YMC I am also among a few other active operators who prefer normal CW, and view with a slight scepticism the claims made by QRS operators of the merits of that mode. However I accept that
From Dave G3YMC I also heard TF1IT at several times on New Year's Day. He was on (or close to) the Ropex frequency but as far as I know did not work anybody. Ron called him a few times later in the d
From Dave G3YMC Following the reports from Alan I can confirm CFH in Halifax, Nova Scotia, was on this morning on 137.0 RTTY. I did not hear it last night when I checked before going to bed, but I se
From Dave G3YMC Just to comment that the CFH transmission on 137.0 has been transmitting RTTY or similar data traffic (its normal mode) and NOT fax. Fax is very characteristic and can be easily recog
From Dave G3YMC Some more points of musing. G0MRF asks what the signal to noise ratio is for CFH. Noise varies enormously between different QTHs, however the signal I receive from CFH during the nigh
From Dave G3YMC G3KEV suggests that loops are very inferior to verticals on 136. He may be right, but experience here is not as pessimistic as he would suggest. I use a loop as a means of getting a s
From Dave G3YMC Mal yesterday and today gave a very detailed signal report on CFH during daylight hours, and his reports, in particular on hearing it at 1530 today, agree largely with the reception h
From Dave G3YMC Friday night was activity night on 73kHz, with more stations on the band at the same time than I have ever known! Rugby was transmitting a different sort of data and the sideband nois
